DISEASES OF THE NERVOUS SYSTEM.

FITS

24th Feb. 1814.--A pug was accustomed to howl frequently when his young master played on the flute. If the higher notes were sounded, he would leap on his master's lap, look in his face, and howl vehemently. To-day the young man purposely blew the shrillest sound that he could. The dog, after howling three or four times, began to run round the room, and over the tables and chairs, barking incessantly. This he continued more than an hour.

When I saw him all consciousness of surrounding objects was gone. He was still running feebly, but barking might and main.

I dashed a basin of cold water in his face, and he dropped as if he had been shot. He lay motionless nearly a minute, and then began to struggle and to bark; another cup of water was dashed in his face, and he lay quite motionless during two minutes or more. In the mean time I had got a grain each of calomel and tartar emetic, which I put on his tongue, and washed it down with a little water. He began to recover, and again began to yelp, although much softer; but, in about a quarter of an hour, sickness commenced, and he ceased his noise. He vomited three or four times, and lay frightened and quiet. A physic-ball was given him in the evening, and on the following morning.

On the next day the young man put open the door, and sat himself down, and began to prepare the flute; the dog was out in a moment, and did not return during a couple of hours. On the following day he made his escape again, and so the matter went on; but before the expiration of the week, his master might play the flute if he pleased.

TURNSIDE, OR GIDDINESS.

This is a singular disease prevalent among cattle, but only occasionally seen in the dog. He becomes listless, dull, off his food, and scarcely recognises any surrounding object. He has no fit, but he wanders about the room fur several hours at a time, generally or almost invariably in the same direction, and with his head on one side. At first he carefully avoids the objects that are in his way; but by degrees his mental faculties become impaired; his sense of vision is confused or lost, and he blunders against everything: in fact, if uninterrupted, he would continue his strange perambulation incessantly, until he was fairly worn out and died in convulsions.

I used to consider the complaint to be uniformly fatal. I have resorted to every remedial measure that the case could suggest. I have bled, and physicked and setoned, and blistered, and used the moxa; but all without avail, for not in a single case did I save my patient.

No opportunity of 'post-mortem' examination was lost. In some cases I have found spicula projecting from the inner plate of the skull, and pressing upon or even penetrating the dura mater. I know not why the dog should be more subject to these irregularities of cranial surface than any of our other patients; but decidedly he is so, and where they have pressed upon the brain, there has been injection of the membranes, and sometimes effusion between them.

In some cases I have found effusion without this external pressure, and, in some cases, but comparatively few, there has not been any perceptible lesion. Hydatids have been found in the different passages leading to the cranium, but they have not penetrated.

I used to recommend that the dog should be destroyed; but I met with two or three favourable cases, and, after that, I determined to try every measure that could possibly be serviceable. I bled, and physicked, and inserted setons, and tried to prevent the utter exhaustion of the animal. When he was unable longer to perform his circumvolutions, and found that he was foiled, he laid himself down, and by degrees resumed his former habits. He was sadly impatient and noisy; but in a few cases he was cured.

[We have seen but two or three cases of this disease in dogs, are led to believe that it is quite uncommon with our domestic animals. One case in a valuable setter came on suddenly, and without any apparent cause (except perhaps over-feeding), and terminated fatally in the course of a few days.--L.]

EPILEPSY

in the dog assumes a most fatal character. It is an accompaniment, or a consequence, of almost every other disease. When the puppy is undergoing the process of dentition, the irritation produced by the pressure of the tooth, as it penetrates the gum, leads on to epilepsy. When he is going through the stages of distemper, with a very little bad treatment, or in spite of the best, fits occur. The degree of intestinal irritation which is caused by worms, is marked by an attack of epilepsy. If the usual exercise be neglected for a few days, and the dog is taken out, and suffered to range as he likes, the accumulation of excitability is expended in a fit.

The dog is, without doubt, the most intellectual animal. He is the companion and the friend of man: he exhibits, and is debased by some of his vices; but, to a greater degree than many will allow, he exhibits all the intelligence and the virtues of the biped. In proportion to his bulk, the weight of his brain far exceeds that of any other quadruped--the very smallest animals alone being excepted, in whom there must be a certain accumulation of medullary matter in order to give origin to the nerves of every system, as numerous in the minutest as in him of greatest bulk.

As it has been said of the human being that great power and exertion of the mental faculties are sometimes connected with a tendency to epilepsy, and, as violent emotions of joy or of grief have been known to be followed by it, I can readily account for its occurrence in the young dog, when frightened at the chiding of his master, or by the dread of a punishment which he was conscious that he had deserved. Then, too, I can understand that, when breaking loose from long confinement, he ranges in all the exuberance of joy; and especially when he flushes almost his first covey, and the game falls dead before him, his mental powers are quite overcome, and he falls into an epileptic fit.

The treatment of epilepsy in the dog is simple, yet often misunderstood. It is connected with distemper in its early stage. It is the produce of inflammation of the mucous passages generally, which an emetic and a purgative will probably, by their direct medicinal effect, relieve, and free the digestive passages from some source of irritation, and by their mechanical action unburthen the respiratory ones.

When it is symptomatic of a weak state of the constitution, or connected with the after stages of distemper, the emeto-purgative must be succeeded by an anodyne, or, at least, by that which will strengthen, but not irritate the patient.

A seton is an admirable auxiliary in epilepsy connected with distemper; it is a counter-irritant and a derivative, and its effects are a salutary discharge, under the influence of which inflammation elsewhere will gradually abate.

I should, however, be cautious of bleeding in distemper fits. I should be fearful of it even in an early stage, because I well know that the acute form of that general mucous inflammation soon passes over, and is succeeded by a debility, from the depression of which I cannot always rouse my patient. When the fits proceed from dentition, I lance the jaws, and give an emetic, and follow it up with cooling purgative medicine. When they are caused by irregular and excessive exercise, I open the bowels and make my exercise more regular and equable. When they arise from excitation, I expose my patient more cautiously to the influence of those things which make so much impression on his little but susceptible mind.

If the fit has resisted other means, bleeding should be resorted to. A fit in other animals is generally connected with dangerous determination of blood to the head, and bleeding is imperative. A fit in the dog may be the consequence of sudden surprise and irritation. If I had the means I should see whether I could not break the charm; whether I could not get rid of the disturbance, by suddenly affecting the nervous system, and the system generally, in another way. I would seize him by the nape of the neck, and, with all my force, dash a little cold water in his face. The shock of this has often dispersed the epileptic agency, as it were by magic. I would give an emeto-purgative; a grain or a grain and a half of calomel and the same quantity of tartar emetic: I would soothe and coax the poor animal. Then,--and if I saw it at the beginning, I would do it early,--if the fit was more dependent upon, or was beginning to be connected with, determination of blood to the head, and not on any temporary cause of excitation or irritation, I would bleed freely from the jugular.

The following singular case of epilepsy is narrated by M.W. Leblanc:

A dog of small size, three years old, was very subject to those epileptic fits that are so frequent among dogs. After a considerable period, the fits would cease, and the animal recover the appearance of perfect health; but the more he advanced in age the more frequent were the fits, which is contrary to that which usually happens.

The last fit was a very strong one, and was followed by peculiar symptoms. The animal became dispirited. The eyes lost their usual lively appearance, and the eyelids were often closed. The dog was very drowsy, and, during sleep, there were observed, from time to time, spasmodic movements, principally of the head and chest. 'He always lay down on the left side'. When he walked, he had a marked propensity to turn to the left.

M. Leblanc employed purgatives, a seton to the back part of the neck, and the application of the cautery to the left side of the forehead; but nothing would stop the progress of the disease, and he died in the course of two months after the last fit. The nearer he approached his end the smaller were the circles that he took; and, in the latter part of his existence, he did little more than turn as if he were on a pivot, and, when the time arrived that he could walk no more, he used to lay himself down on the right side.

On the 'post-mortem' examination, a remarkable thickness of the meninges was found on almost the whole of the left lobe of the brain. The dura mater, the two leaves of the arachnoid membrane, and the pia mater did not constitute more than one membrane of the usual thickness, and presented a somewhat yellow colouring. The cerebral substance of the left lobe appeared to be a little firmer than that of the right lobe. The fissures of the cerebral devolutions were much less deep than those of the other side The red vessels which ran in the fissures were of smaller size, and in some places could scarcely be discovered.

[Confinement, over-feeding, blows on the head or spine, drying up of old ulcers, repelling of cutaneous affections, or, in fact, anything that is liable to derange the general health of the animal, will produce epileptic fits.

We formerly had a beagle hound of very active temperament, which we were necessarily obliged to keep much confined while in the city; and to restrain her from running too wildly when taken into the streets, we were in the habit of coupling her with a greyhound of much milder disposition. Not being willing to submit lamely to this unpleasant check upon her liberty, she was ever making fruitless attempts to escape, either by thrusting herself forwards, or obstinately pulling backwards. These efforts resulted on several occasions in fits, produced by congestion of the brain, owing to the pressure of the collar on the neck, thereby interrupting the circulation, and inducing an influx of blood to those parts. We were ultimately obliged to abandon this method of restraint, which nearly proved fatal to our much-admired beagle: she being suddenly seized with one of these fits on a hot summer's day in one of our principal thoroughfares, the crowd of ignorant bystanders concluded it to be a case of rabies, and nothing but my taking her up in my arms, and carrying her from the scene of action, saved her from falling a victim to their ignorance.

If the disease appears dependent upon plethora the result of confinement and gross living, the animal must be reduced by bleeding and purging, low diet, and exercise. If, however, the malady proceeds from weakness, as is sometimes the case in bitches while suckling a large litter, it will be necessary to relieve her of some of the pups, and supply her with the most nutritious diet, as also administer tonic balls; the following will answer.

[Symbol: Rx]: Extract of Gentian, Quassia, ââ (each) grs. V, made into two pills, and one or two given morning and evening;

or,

[Symbol: Rx]: Powdered Columbo. Carbonate of Iron, ââ, grs. V, made into two pills, and one given morning and evening, or more frequently if desirable.

A seton placed in the poll will often prevent these attacks, particularly when depending upon slight cerebral irritation, accompanying distemper and mange. Blisters and frictions to the spine are also serviceable.--L.]

CHOREA.

This is an irregular reception or distribution of nervous power--a convulsive involuntary twitching of some muscle or set of muscles. It is an occasional consequence of distemper that has been unusually severe or imperfectly treated, and sometimes it is seen even after that disease has existed in its mildest form.

[This nervous affection, more commonly known as St. Vitus' dance, is not a rare disease, and we doubt not that examples of it have been seen by most of our readers, more particularly in young dogs affected with distemper.

This malady is characterized by sudden involuntary twitchings of the different muscles of the body, the disease being sometimes confined to one limb, sometimes to two, and frequently pervades the whole system, giving the dog a distressing and painful appearance. These involuntary motions, it is very true, are generally restricted during sleep, although in old chronic cases of long standing they often continue in full activity without any remission whatever. The disease is not attended with fever, and all the functions generally remain for a considerable time unimpaired.--L.]

It first appears in one leg or shoulder, and is long, or perhaps entirely, confined to that limb. There is a singular spasmodic jerking action of the limb. It looks like a series of pulsations, and averages from forty to sixty in a minute. Oftener, perhaps, than otherwise, both legs are similarly affected. When the animal is lying down, the legs are convulsed in the way that I have described, and when he stands there is a pulsating depressing or sinking of the head and neck. In some cases, the muscles of the neck are the principal seat of the disease, or some muscle of the face; the temporal muscle beating like an artery; the masseter opening and closing the mouth, the muscles of the eyelid, and, in a few cases, those of the eye itself being affected. These convulsive movements generally, yet not uniformly, cease during sleep, but that sleep is often very much disturbed. If the case is neglected, and the dog is in a debilitated state, this spasmodic action steals over the whole frame, and he lies extended with every limb in constant and spasmodic action.

In the majority of cases, such an expenditure of nervous and muscular power slowly destroys the strength of the animal, and he dies a mere skeleton; or the disease assumes the character of epilepsy, or it quiets down into true palsy.

In the most favourable cases, no curative means having been used, the dog regains his flesh and general strength; but the chorea continues, the spasmodic action, however, being much lessened. At other times, it seems to have disappeared; but it is ready to return when the animal is excited or attacked by other disease. In a variety of instances, there is the irritable temper which accompanies chorea in the human being, and most certainly when the disease has been extensive and confirmed.

Chorea, neglected or improperly treated, or too frequently pursuing its natural course, degenerates into paralysis agitans. There is a tremulous or violent motion of almost every limb. The spasms are not relaxed, but are even increased during sleep, and when the animal awakes, he rises with agitation and alarm. There is not a limb under the perfect control of the will; there is not a moment's respite; the constitution soon sinks, and the animal dies. No person should be induced to undertake the cure of such a case: the owner should be persuaded to permit a speedy termination to a life which no skill can render comfortable.

Chorea is oftenest observed in young dogs, and especially after distemper; and it seems to depend on a certain degree of primary or sympathetic inflammatory affection of the brain.

Chorea is often very plainly a consequence of debility: either the distribution of nervous power is irregular, or the muscles have lost their power of being readily acted upon, or have acquired a state of morbid irritability. The latter is the most frequent state. Their action is irregular and spasmodic, and it resembles the struggles of expiring nature far more than the great and uniform action of health. It is not the chorea that used to be described, in which there was an irresistible impulse to excessive action, and which was best combated by complete muscular exhaustion; but the foundation of this disease is palpable debility.

[Rickets, bad feeding, cold and damp housing, worms in the alimentary canal, mange, and other chronic affections, are all forerunners of this malady.--L.]

In the treatment of chorea there must be no bleeding, no excessive purgation, but aperients or alteratives, merely sufficient to keep the fæces in a pultaceous state, so as to carry off any source of irritation to the intestinal canal, and particularly some species of worms, too frequent sources of irritation there. To these should be added nutritious food, gentle exercise, tonic medicines, and general comforts. Counter-irritants may be applied--such as blisters over the head, and setons, extending from poll to poll--the application of turpentine, or the tincture of cantharides; but all of these will frequently be of no effect, and occasionally a rapid and fearful increase of irritability will ensue: antispasmodics are in this case of no use, and narcotics are altogether powerless. As for tonics, iron and gentian have been serviceable to a certain extent, but they have never cured the complaint. The nitrate of silver will be the sheet-anchor of the practitioner, and if early used will seldom deceive him. It should be combined with ginger, and given morning and night, in doses varying from one-sixth to one-third of a grain, according to the size of the dog.

The condition and strength of the dog, and the season of the year, will be our best guides. If the patient has not lost much flesh, and is not losing it at the time that we have to do with him, and has few symptoms of general debility, and spring or summer are approaching we may with tolerable confidence predict a cure; but, if he has been rapidly losing ground, and is doing so still, and staggers about and falls, there is no medicine that will restore him.

5th October, 1840.--A pointer, eighteen months old, had had the distemper, but not severely, and was apparently recovering when he suddenly lost all voluntary power over his limbs. He was unable to get up, and his legs were in constant, rapid, and violent motion. This continued three days, during which he had refused all food, when, the dog being in the country, my advice was asked. I ordered a strong emetic to be given to him, and after that a dose of Epsom salts, the insertion of a seton, and, in addition to this, our usual tonic was to be given twice every day. His food to consist chiefly of good strong soup, which was to be forced upon him in a sufficient quantity.

In two days he was able to get up and stagger about, although frequently falling. His appetite returned. He continued to improve, and most rapidly gained strength and especially flesh. A very peculiar, high-lifting, clambering, and uncertain motion of the legs remained, with an apparent defect of sight, for he ran against almost everything.

In six weeks the seton was removed, and the dog remained in the same state until the 7th of December. The uncertain clambering motion was now increasing, and likewise the defect of sight. He ran against almost every person and every thing. The cornea was transparent, the iris contracted, there was no opacity of the lens, or pink tint of the retina, but a peculiar glassy appearance, as unconscious of everything around it. An emetic was given, and, after that, an ounce of sulphate of magnesia.

8th. He was dreadfully ill after taking the salts; perhaps they were not genuine. For two days he panted sadly, refused his food, and vomited that which was forced upon him. His muzzle was hot; he could scarcely stand; he lost flesh very rapidly. An emetic was given immediately, and a distemper-ball daily.

16th. He soon began rapidly to recover, until he was in nearly the same state as before, except that the sight was apparently more deficient. The sulphate of magnesia was given every fourth day, and another seton inserted.

21st. He continued the medicine, and evidently improved, the sight returning, and the spasms being considerably less. The distemper-ball was continued.

4th January, 1841.--The spasms were better; but the vision did not improve. In the afternoon he fell into a momentary fit. He almost immediately rose again, and proceeded as if nothing had happened. An ounce of Epson salts was given, and then the tonic balls as before.

22d. The spasms were lessened, the clambering gait nearly ceased, but the vision was not improved. The seton was removed, and only an additional dose of salts given.

27th. The spasms suddenly and very considerably increased. The left side appeared now to be particularly affected. The left leg before and behind were most spasmed, the right scarcely at all so. The vision of the left eye was quite gone. The dog had been taken to Mr. Alexander's, the oculist, who attributed the affection of the eye and the general spasmodic disease to some pressure on the brain, and recommended the trial of copious and repeated bleeding.

28th. The dog was dull; the spasms appeared to have somewhat increased and decidedly to affect the left side. Fever-balls were ordered to be given.

29th. Considerable change took place. At three o'clock this morning I was disturbed by a noise in the hospital. The poor fellow was in a violent fit. Water was dashed in his face, and a strong emetic given; but it was not until seven o'clock that the fit had ceased; he lay until eleven o'clock, when the involuntary spasms were almost suspended. When he was placed on his feet, he immediately fell; he then gradually revived and staggered about. His master brought a physician to see him, who adopted Mr. Alexander's idea and urged bleeding. Ten ounces of blood were immediately taken; the dog refused to eat.

1st February.--The strength of the animal was not impaired, but the spasms were more violent, and he lay or wandered about stupid and almost unconscious. I subtracted eight ounces more of blood.

2d. The spasms were fully as violent, and no amendment in the vision. Eight ounces more of blood were subtracted without benefit. A fever-ball was ordered to be given.

3d. No amendment; but the bleeding having been carried to its full extent, I again resorted to the tonic balls, which were given morning and night. The dog was well fed and the seton replaced.

5th. A very considerable amendment is evident.

9th. The spasms rapidly subsided and almost disappeared. Vision was not perfectly restored; but the dog evidently saw with his left eye. He was taken away, and tonic balls sent with him and ordered to be continued.

6th March.--The dog had improved in strength and no spasmodic affection remained; he likewise evidently saw with his left eye. The tonic-balls had been discontinued for a week, and his master hoped that all would turn out well, when suddenly, while at home, he was seized with a fit that lasted ten minutes. A strong emetic was given, which brought up a vast quantity of undigested food. A strong purging-ball was given to him in the evening.

13th. The dog had lain slightly spasmed for two or three days, when they all at once ceased, and the animal appeared as well as before. Suddenly he was taken with another fit, and again a vast quantity of food was vomited. These spasms remained two days, but on the 21st the fit returned with the same discharge of food. Courses of purgatives were then determined on. A strong dose of sulphate of magnesia was given every third day. After four doses had been given, it was impossible to force any more upon him. The syrup of buckthorn was tried, but the fourth dose of that it was impossible to give. The dog was then sent into the country; no fit occurred, but there were occasional spasms.

23d September.--He was brought back to town, and I saw him. During the last month he had had many fits. His owner at length consented that the actual cautery should be applied to his head. The searing-iron for doctoring was used, and applied red-hot to the centre of the head. It was exceedingly difficult so to confine the dog as to make the application effectual, without destroying the skin.

Under the influence of the sudden violent pain, he wandered about for more than two hours, and then the spasms returned with greater force than usual. He refused all food.

We determined to try the cautery to its full extent. We chained him up in the morning, and penetrated through the skin with the budding-iron. The spasms were dreadfully violent, and he was scarcely able to walk or to stand. This gradually subsided, and then he began to run round and round, and that increased to an extraordinary velocity: he would then lie for a while with every limb in action. The owner then yielded to all our wishes, and he was destroyed with prussic acid. No morbid appearance presented itself in the brain; but, on the inner plate of the right parietal bone, near the sagittal suture, were two projections, one-sixth of an inch in length, and armed with numerous minute spicula. There was no peculiar inflammation or vascularity of any other part of the brain.

[We once cured a case quite accidentally, by throwing a pup into a cold stream of water, and making him swim ashore; we do not recommend the plan, although we should be willing to try it again with one of our own dogs. The animal should be forced to swim till nearly exhausted, and wrapped up in blankets on coming out of the water. The intense alarm created in the pup, together with the violent struggle and coldness of the water, all act as revulsives to the disease, which, if purely nervous, may be overcome by these powerful agents.

If the dog be weak, and the stomach deranged, the following tonic balls will answer a good purpose:

[Symbol: Rx]: Carbonate of Iron.

Ground Ginger, ââ, grs. X, made into two pills, one given morning and evening, or more frequently according to the age or size of the animal.--L.]

RHEUMATISM AND PALSY.

I do not know any animal so subject to 'rheumatism' as the dog, nor any one in which, if it is early and properly treated, it is so manageable.

[We agree with our author, that the canine family are exceedingly liable to inflammation of the fibrous and muscular structures of the body, and there is no disease from which they suffer more, both in their youth and old age, than rheumatism. No particular species of dogs are more subject to its attacks than others, all being alike victims to its ravages. Mr. Blaine remarks, that the bowels always sympathize with other parts of the body suffering under this disease, and that inflammation will always be found existing in the abdominal viscera, if rheumatism be present, and the lower bowels will be attended with a painful torpor, which he designates as rheumatic colic. We ourselves noticed, that old setters particularly, when suffering from this disease, are frequently attacked with an acute diarrhoea, or suffer from obstinate constipation attended by griping pains, but did not know that this state of things was so uniform an accompaniment to the other affection. There are two varieties of rheumatism, the 'acute' and 'chronic', both of which are attended with either general fever or local inflammation. The attacks usually come on rather suddenly, the joints swell, the pulse becomes full and tense, the parts tender, and the eyes blood-shot, the stomach deranged, and the bowels costive. Severe lancinating pain runs through the articulation, and along the course of the larger muscles, the tongue is coated, the muzzle hot and dry, and the poor animal howls with agony. The breathing becomes laboured, all food is rejected, and if you attempt to move the sufferer he sends forth piteous cries of distress. 'The causes' of this serious affection are very numerous; among the most usual and active agents may be enumerated, exposure to atmospherical vicissitudes, remaining wet and idle after coming from the water, damp kennels, suppressed perspiration, metastasis of eruptive diseases, luxurious living, laziness and over-feeding. These and many other causes are all busy in the production of this disease. Duck dogs on the Chesapeake, we have noticed as often suffering from this affection, owing no doubt to the great exposure they are obliged to endure; but few of them arrive at old age without being martyrs to the chronic form. 'Chronic rheumatism', generally the result of the other form of disease, is most usually met with in old dogs: it is attended with little fever, although the local inflammation and swelling is sometimes considerable. The pain is often stationary in one shoulder or loin, at other times shifts about suddenly to other portions of the body. The muscles are tender and the joints stiff, the animal seems lame till he becomes healed, and limber when all appearance of the disease vanishes. In old cases the limbs become so much enlarged, and the joints so swollen, that the dog is rendered perfectly useless, and consequently increases his sufferings by idleness. 'This form of the disease is known as gout.'

Treatment of 'acute rheumatism'--bleeding largely is very important in this affection, and if followed up with two or three purges of aloes, gamboge, colocynth and calomel will arrest the progress of this disease.

Rx. Extract of Colocynth 3 [Symbol: scruple] i. Calomel grs. x. Powdered Gamboge grs. ii. Socet. Aloes grs. x.

Made into four pills, two to be given at night, and the other the following morning. If these medicines should not be handy, give a large purging ball of aloes, to be followed by a full dose of salts. When the inflammatory action is not sufficiently high to demand depletion, warm bathing, friction and keeping the dog wrapped up in blankets before a fire will generally afford relief. If the pain appear very severe, it will be necessary to repeat the baths at short intervals: great attention must be paid to the state of the bowels: if a diarrhoea supervenes, it must not he checked too suddenly, by the use of astringent medicines, but rather corrected by small doses of oil and magnesia. If constipation attended with colic be the character of the affection, small quantities of oil and turpentine in connexion with warm enemata will be the proper remedies. If paralysis should occur, it will be found very difficult to overcome, but must be treated, after the reduction of inflammation, upon principles laid down under the head of this latter affection. Blisters to the spine, setons, electricity, acupuncturation, &c.

'Treatment of chronic rheumatism'--warm baths are useful, and warm housing absolutely necessary, attention to diet, and an occasional purge of blue mass and aloes, together with electricity, acupuncture, rubefacient applications to the spine, &c.--L.]

A warm bath--perchance a bleeding--a dose or two of the castor-oil mixture, and an embrocation composed of spirit of turpentine, hartshorn, camphorated spirit, and laudanum, will usually remove it in two or three days, unless it is complicated with muscular sprains, or other lesions, such as the 'chest-founder' of kennels.

This chest-founder is a singular complaint, and often a pest in kennels that are built in low situations, and where bad management prevails. Where the huntsman or whippers-in are too often in a hurry to get home, and turn their dogs into the kennel panting and hot; where the beds are not far enough from the floor, or the building, if it should be in a sufficiently elevated situation, has yet a northern aspect and is unsheltered from the blast, chest-founder prevails; and I have known half the pack affected by it after a severe run, the scent breast-high, and the morning unusually cold. It even occasionally passes on into palsy.

The veterinary surgeon will be sometimes consulted respecting this provoking muscular affection. His advice will comprise--dryness, attention to the bowels, attention to the exercise-ground, and perhaps, occasionally, setons--not where the huntsman generally places them, on the withers above, but on the brisket below, and defended from the teeth of the dog by a roller of a very simple construction, passing round the chest between the fore legs and over the front of the shoulders on either side.

The pointer, somewhat too heavy before, and hardly worked, becomes what is called chest-foundered. From his very make it is evident that, in long-continued and considerable exertion, the subscapular muscles will be liable to sprain and inflammation. There will be inflammation of the fasciæ, induration, loss of power, loss of nervous influence and palsy. Cattle, driven far and fast to the market, suffer from the same causes.

[By palsy, we mean a partial or complete loss of the powers of motion or sensation in some portion of the muscular system: this affection is very common to the canine race, and very few of them reach an advanced age without having at some time in their life experienced an attack of this malady.

The loins and hind legs suffer oftener than other parts, in fact we do not recollect ever meeting with paralysis of the fore limbs alone. Although the limbs become perfectly powerless, and are only dragged after the animal by the combined efforts of the fore legs and back, it is seldom that they lose their sensibility.--L.]

Palsy is frequent, as in the dog. However easy it may be to subdue a rheumatic affection, in its early stage, by prompt attention, yet if it is neglected, it very soon simulates, or becomes essentially connected with, or converted into, palsy.

No animal presents a more striking illustration of the connexion between intestinal irritation and palsy than the dog. He rarely or never has enteritis, even in its mildest form, without some loss of power over the hinder extremities. This may at first arise from the participation of the lumbar muscles with the intestinal irritation; but, if the disease of the bowels continues long, it will be evident enough that it is not pain alone that produces the constrained and incomplete action of the muscles of the hind extremities, but that there is an actual loss of nervous power. A dog is often brought to the veterinary surgeon, with no apparent disease about him except a staggering walk from weakness of the hind limbs. He eats well and is cheerful, and his muzzle is moist and cool; but his belly is tucked up, and there are two longitudinal cords, running parallel to each other, which will scarcely yield to pressure. The surgeon orders the castor-oil mixture twice or thrice daily, until the bowels are well acted upon, and, as soon as that is accomplished, the dog is as strong and as well as ever. Perhaps his hind limbs are dragged behind him; a warm bath is ordered, he is dosed well with the castor-oil mixture, and, if it is a recent case, the animal is well in a few days. In more confirmed palsy, the charge, or plaster on the loins, is added to the action of the aperient on the bowels. The process may be somewhat slow, but it is seldom that the dog does not ultimately and perfectly recover.

It is easy to explain this connexion, although we should have scarcely supposed that it would have been so intimate, had not frequent experience forced it on our observation. The rectum passes through the pelvis. Whatever may be said of that intestine, considering its vertical position in the human being, it is always charged with fæces in the quadruped. It therefore shares more in the effect, whatever that may be, which is produced by the retention of fæces in the intestinal canal, and it shares also in the inflammatory affection of other parts of the canal. Almost in contact with this viscus, or at least passing through the pelvis, are the crural nerves from the lumbar vertebræ, the obtusator running round the rim of the pelvis, the glutal nerve occupying its back, and the sciatic hastening to escape from it. It is not difficult to imagine that these, to a certain degree, will sympathize with the healthy and also the morbid state of the rectum; and that, when it is inert, or asleep, or diseased, they also may be powerless too. Here is something like fact to establish a very important theory, and which should be deeply considered by the sportsman and the surgeon.

[Loss of the contractile power of the sphincters of the bladder and rectum, sometimes attends this disease, and involuntary evacuations are constantly taking place, or costiveness and retention are the consequences.--L.]

Mr. Dupuy has given a valuable account of the knowledge we possess of the diseases of the spinal marrow in our domestic quadrupeds.

He has proved:

1. That in our domestic animals the spinal marrow is scarcely ever affected through the whole of its course.

2. That the dorsal and lumbar regions are the parts oftenest affected.

3. That inflammation of the spinal marrow of these regions always produces palsy, more or less complete, of the abdominal members.

4. That, in some cases, this inflammation is limited to the inferior or superior parts of the spinal marrow, and that there is loss only of feeling or of motion.

5. That sometimes animals die of palsy without any organic lesion.

[Blows on the head, producing effusion on the brain, poisoning by lead, inflammation of the spinal marrow, affections of the nerves, caries of the spine, costiveness and affections of the bowels, are all productive of palsy. If the disease proceeds from rheumatism, or other inflammatory affections, independent of any organic lesion, the disease, if taken early, is not difficult to overcome in the young subject. Warm baths, bleeding, purging, and stimulating applications to the parts and along the spine, will answer. Castor oil and turpentine is a good purge: where the malady depends upon costiveness, purges of aloes should be administered in connexion with warm enemata, stimulating frictions along the spine, and hot baths. Croton oil dropped on the tongue will also be of great benefit: if there should be effusion or compression from fracture of the bones of the cranium, nothing but trephining will be of any service, as we can hardly hope for the absorption of the matter, and the removal of the spicula of bone can alone afford relief to the patient. Paralysis arising from poisoning should be treated as described under the head of mineral poisons. Chronic cases of paralysis arising from want of tone of the nerves and spinal marrow, repeated blistering, introduction of the seton along the spine, electricity, &c., have all been tried with some success.

Strychnia, from its peculiar effects upon the animal economy, and its almost exclusive direction to the nerves of motion, makes it a medicine particularly applicable to the treatment of this disease. It may be given in all stages of the malady, but is most serviceable after the reduction of inflammatory action, and when we are convinced that the disease depends upon want of tone in the motor muscles.

Great care should be had in its administration, as it is a powerful poison in too large doses, to a large dog; commence with a quarter of a grain in pill, three times daily, and gradually increase to a half grain or more if the animal seems to bear it well. But it should be discontinued immediately on the appearance of any constitutional symptoms, such as spasmodic twitchings of the eyelids or muzzle.--L.]

PALSY--MANGE

11th February, 1835.--A Persian bitch, at the Zoological Gardens, who was well yesterday, now staggers as she walks, and has nearly lost the use of her hind legs. Gave a good dose of the castor-oil mixture.

18th. She is materially worse and drags her hind legs after her. I would fain put on a charge, but the keeper does not like that her beautiful coat should be spoiled, and wishes to try what gentle exercise will do. She certainly, after she has been coaxed a great deal, will get on her legs and stagger on fifty yards or more. Gave the castor-oil mixture daily.

19th. She is a little stronger, and walks a little better. Continue the mixture. Embrocate well with the rheumatic mixture--sp. tereb., sp. camph., liq. ammon., et tinct. opii--and give gentle exercise.

2d March.--She does improve, although slowly; the charge is therefore postponed. Continue treatment.

30th. She is considerably better. Continue the mixture, and use the embrocation every second day.

10th April--She has mange in the bend of her arm, and on her chest. Use the sulphur ointment and alterative balls, and omit the embrocation and mixture. In less than a week she nearly recovered from her lameness, and ran about almost as well as ever.

30th. She runs about very fairly, but the mange has assumed that character of scurvy which I do not know how to grapple with. Continue the alterative balls, and the ointment.

18th May.--The mange has disappeared, but the palsy is returning; she staggers slightly, and droops behind. Give the castor-oil mixture and use the embrocation.

14th June.--Mange quite gone, but palsy continues to a very considerable degree. I want to use the plaster; but the keeper pleads for a little delay. Continue the treatment.

1st July.--I have at length determined to have recourse to the charge. A piece of thick sheep's leather was fitted lo her loins and haunches. 18th. She appears to be improving, but it is very slowly.

31st. Very little change. The plaster keeps on well: she has no power over her hind limbs; but she eats and drinks as well as ever.

23d August.--No change. Give her half a grain of strychnia, morning and night.

26th That singular secretion of milk, to which the bitch is subject nine weeks after oestrum, is now appearing. Her mammæ are enlarged, and I can squeeze a considerable quantity of milk out of the teats. Give an aloetic pill, and continue the strychnia.

31st. The secretion of milk continues. There is slight enlargement and some heat of the mammæ; but she feeds as well as ever. Increase the dose of strychnia to three-quarters of a grain.

On the following day she was found dead. In making the usual longitudinal incision through the integuments of the abdomen a considerable quantity of milky fluid, mingled with blood, followed the knife. There was very slight enlargement of the teats, but intense inflammation of the whole of the mammary substance. The omentum, and particularly the portion opposite to the external disease, was also inflamed. Besides this there was not a vestige of disease.

This is an interesting case and deserves record. I fear that justice was not done to the animal at the commencement of the paralytic affection. In nineteen cases out of twenty in the dog, the constant but mild stimulus of a charge over the lumbar and sacral regions removes the deeper-seated inflammation of the spinal cord or its membranes, when the palsy is confined to the hind extremities, and has not been sufficiently long established to produce serious change of structure. The charge should have been applied at first. The almost total disappearance of the palsy during the cutaneous disease, which was attended with more than usual inflammation of the integument, is an instructive illustration of the power of counter-irritation, and of what might possibly have been effected in the first case; for much time was lost before the application of the charge, and when at length it was applied, it and the strychnia were powerless.

I consider the following case as exceedingly valuable, at least with reference to the power of strychnia in removing palsy:--

19th August, 1836.--A fine Alpine dog was suddenly attacked with a strange nervous affection. He was continually staggering about and falling. His head was forcibly bent backward and a little on one side, almost to his shoulder. A pound of blood was abstracted, a seton inserted from ear to ear, and eight grains of calomel administered.

21st. He has perfectly lost the use of every limb. He has also amaurosis. perfect blindness, which had not appeared the day before. He hears perfectly, and he eats, and with appetite, when the food is put into his mouth. Gave him two large spoonfuls of the castor-oil mixture daily; this consists of three parts of castor-oil, two of syrup of buck-thorn, and one of syrup of white poppies.

23d. A little better; can lift his head and throw it upon his side, and will still eat when fed. Continue the mixture, and give half a grain of strychnia daily.

24th. Little change.

27th. No change, except that he is rapidly losing flesh. Continue the treatment.

31th. The strychnia increased to three-fourths of a grain morning and night. The castor-oil mixture continued in its full quantity. He was fed well, but there was a sunken, vacant expression of countenance.

2d September.--He can move his head a little, and has some slight motion in his limbs.

4th. He can almost get up. He recognises me for the first time. His appetite, which was never much impaired, has returned: this is to be attributed to strychnia, or the seton, or the daily aperient mixture. They have all, perhaps, been serviceable, but I attribute most to the strychnia; for I have rarely, indeed, seen any dog recover from such an attack. Continue the treatment.

6th. Fast recovering. Medicine as before.

14th. Improving, but not so fast as before. Still continue the treatment.

28th. Going on slowly, but satisfactorily. Remove the seton, but continue the other treatment.

13th October.--Quite well.
