Curiosities of Medical Experience
Part 12
While water was thus freely drunk, wine was not disregarded; but the various articles with which it was adulterated, must have rendered it any thing but a delectable potation according to our received ideas. Thus we see the Greeks putting salt and sea-water in theirs; at other times dissolving mastic and myrrha, or infusing wormwood, in their choicest Falernian. Like modern tasters, however, they knew the method of developing the _bouquet_ by warmth; and, to appreciate the flavour, they frequently added hot water. That wines of a resinous taste were esteemed, appears from Martial:
Resinata bibis vina, Falerna fugis.
But we may conclude that, according to our modern taste, their boasted wines did not equal ours either in flavour or in delicacy.
The ancients however were very careful in the preparation of their bread, justly called the "staff of life," as constituting one of the most wholesome and nutritious parts of our food. The Athenian bakers bore the palm in the confection of this article. Archestratus recommended the wheaten bread of Athens and the barley meal of Lesbos, which their poets asserted was supplied to the gods. The Grecian millet bread was also in great repute, while delicious bread was also made with the _Zea_, the _Triticum Spella_ of Linnæus and the _Far_ of the Romans. A species of wheat called _Tiphe_ was also much esteemed. Brown bread was made of a grain called _Olyra_, and it was with loaves of this description that Homer's heroes fed their horses.
It appears that great attention was paid to the kneeding and the boulting: unboulted meal was called _Syncomista_, and when finely boulted in a woollen cloth, _Semidalis_. The most approved method of baking was in the _Cribanus_ or _Clibanus_, an earthen or iron vessel, which they surrounded with charcoal. Bread according to its superior or inferior quality was consecrated to various divinities. Thus the goddesses used the _Homoros_, and Hecate was served with the _Hemiantium_, but we are unacquainted with the preparation of these varieties. The flour of barley was used by the _Canephoræ_, or virgins that bore the sacred baskets in the festivals of Ceres, to sprinkle themselves. Bread according to its particular kind was served up in various ways; wheaten bread was brought to table upon fresh leaves; barley bread upon a layer of reeds. At the feasts of Ceres and Proserpine, a large loaf was kneeded and baked by the ladies of Delos, called _Achaïnas_ which gave the name to the festival, instituted most probably in Achaia, to commemorate the invention of bread, which Ceres taught to Eumelus, a citizen of Patræ.
Barley for the preparation of bread was used long before wheat or any other sort of corn, and hence Artemidorus calls it _Antiquissimum in cibis_. It was also given to the athletæ who were thence called _Hordearii_. In latter times it was chiefly given to cattle, although used by the poorer classes. Barley bread was also issued to soldiers as a punishment, the loss of wheaten bread being considered a great privation. Vegetius tells us that soldiers who had been guilty of any offence were thus punished--"_hordeum pro frumentuo cogebantur accipere_." In the second Punic war we find Marcellus sentencing the cohorts that had lost their standards to this infliction. Suetonius also informs us that Augustus only allowed barley to the troops that had misbehaved in action. _Cohortes, si quæ cepissent, loco, decimatas hordeo pavit._ But there is reason to believe that under the head of bread were included various kinds of cakes, many of which were prepared with honey, some of them were called _Placentæ omnigenæ_, and were prepared by bakers who bore the name of _pistores dulciarii_. This honied bread or cake it appears, was frequently resorted to, as in the present day, to quiet troublesome children as well as to please the taste of fastidious patients. Thus Martial:
Leniat ut fauces medicus, quas aspera vexat Assiduè tussis, Parthenopæ tibi Mella dari, nucleosque jubet dulcesque placentas. Est quidquid pueros non sinit esse truces, At tu non cessas totis tussire diebus Non est hæc tussis, Parthenopæ gula est.
The bread made of spring wheat was called _Collabus_, and the Athenians considered a toasted _Collabus_ eaten with a slice of a pig's belly, the very best cure for a surfeit occasioned by an excess in anchovies, especially the Phalerian ones, which were deemed fit for the gods.
Fragments of bread it appears were used instead of napkins to wipe the fingers on. These were called _Apomygdaliæ_, with which Aristophanes fed his sausage-makers. These dainty bits were usually thrown to dogs.
The cooks of the ancients appear to have been much more consummate in their art than our modern practitioners. Athenæus records various descriptions of their incomparable science. A new dish immortalized its inventor, and transmitted his name to posterity. Apicius's cakes were called Apicians; and Aristoxenes had attained such perfection in curing hams, that the glorious appellation of Aristoxenians was bestowed upon them. Philosophers and poets gloried in their culinary science; the pleasures of the table were the subject of their writings and their conversation. Archestratus tells us with delight, that, although various delicacies can only be enjoyed in their proper season, yet we can talk about them with watering mouths all the year round.
One of these illustrious ministers of luxury attained such a degree of enviable perfection, that he could serve up a pig boiled on one side and roasted on the other, and moreover stuffed with all possible delicacies, without the incision through which these dainties were introduced being perceived. Supplicated to explain this wonderful secret, he swore solemnly by the manes of all the heroes who fell at Marathon, or conquered at Salamis, that he would not reveal this sacred mystery for one year. When the happy day arrived and he was no longer bound by his vows, he condescended to inform his anxious hearers, that the animal had been bled to death by a wound under the shoulder, through which the entrails were extracted; and afterwards hanging up the victim by the legs, the stuffing was crammed down his throat. One half of the pig was then covered with a thick paste, seasoned with wine and oil, put into a brass oven, and gently and tenderly roasted: when the skin was brown and crisp, our hero proceeded to boil the other moiety; the paste was then removed, and the boiled and roasted grunter triumphantly served up.
So refined was the taste of the ancient _bons vivans_, that Montanus, according to Juvenal, would proclaim, at the first bite, whether an oyster was of English produce or not. Sandwich is believed to have been the favoured spot whence Rome imported her oysters and other shell-fish. Shrimps and prawns must have been in great estimation, since we find Apicius quitting his residence at Minturnæ, upon hearing that the shrimps of Africa were finer than those he could procure in Campania. He instantly set sail for the happy coast, despite a gale of wind: after encountering a desperate storm, he reached the wished-for land of promise; but alas!--the fishermen displayed the largest prawns they could collect, and to his cruel disappointment, they could not vie, either in delicacy or beauty, with those of Minturnæ. He immediately ordered his pilot to steer a homeward course, and left Africa's shore with ineffable contempt.
These ingenious gluttons had recourse to every experiment that could add to their enjoyment. Philoxenus, and many others, used to accustom themselves to swallow hot water, that they might be able to attack scalding dishes before less fireproof guests would dare to taste them.
Sinon maintained that cookery was the basis of all arts and sciences: natural philosophy taught us the seasoning of dishes; architecture directed the construction of stoves and chimneys; the fine arts, the beautiful symmetry of each dish; and the principles of war were applied to the drilling and marshalling of cooks, confectioners, and scullions, posting proper sentries to watch the fires, and videttes to keep off idle intruders. That man is a "cooking animal" is considered one of his proudest attributes, and a proper bill of fare may be considered as the _ne plus ultra_ of human genius!
It may be easily imagined that when good living became a science, _sponging_ upon the wealthy _Amphitryons_ became an art amongst the needy _bons vivants_, and parasites, as in the present day, were ever seen fawning and cringing for their dinner. These sycophants stuck so close to their patrons, that they were called shadows. Thus Horace:
----Quos Moecenas adduxerat umbras.
They were also called flies, [Greek: gyias], by the Greeks, and _Muscæ_ by the Romans; no doubt from their constant buzzing about the object of their devotion. Plautus calls an entertainment free from these despicable guests, _Hospitium sine muscis_. Horus Apollo tells us that in Egypt a fly was the symbol of an impudent fellow; because, although driven away, it will constantly return. We have, however, reason to believe that the term _parasite_ was originally applied to the followers of princes, Patroclus was the parasite of Achilles, and Memnon of Idomeneus; it was only in later times that the appellation was given to despicable characters and "_trencher friends_."
Our Shakspeare had adopted the term of the ancients, as appears in the following passages:
In such as you, That creep like _shadows_ by him, and do sigh At each his needless heavings.
And again--
Feast-won, fast-lost, one cloud of winter showers. These _flies_ are couched.
While climate points out the most suitable articles of food, it exercises a singular influence over their qualities and properties, more especially in vegetable substances. We find plants which are poisonous in some countries, edible and wholesome in others. Next to climate, culture and soil modify plants to a singular degree: flowers which yield a powerful perfume in some latitudes, are inodorous in others; and, according to climate, their aroma is pleasant or distressing. A striking proof of this fact can be adduced from the well-known effects of perfumes in Rome; where the inhabitants, especially females, cannot support the scent even of the rose, which has been known to produce syncope, illustrating the poet's line to
Die of a rose in aromatic pain.
This variety in the action of vegetable substances is more particularly observable in such as are considered medicinal. Opium, narcotics, and various drugs, are more powerful in warm climates than in northern regions. The Italian physicians express astonishment at the comparatively large doses prescribed by our practitioners.
Cultivation brings forth singular intermediate productions; and by its magic power we have seen the coriaceous and bitter almond transformed into the luscious peach, the sloe converted into the delicious plum, and the common crab transformed into the golden pippin. The same facts are observed in vegetables; the celery sprung from the nauseous and bitter _apium graveolens_, and the colewort, is metamorphosed into the cabbage and the cauliflower. All cruciform plants degenerate within the tropics, but acquire increased energies in cold countries.
Recent experiments in Germany have demonstrated that in times of scarcity, the wood of several trees may be converted into a nutritious substance. The fibres of the beech, birch, lime, poplar, fir, and various other trees, when dried, ground, and sifted into an impalpable powder, constitute a very palatable article of food. If cold water be poured on this ligneous flour, enclosed in a linen bag, it becomes milky, and considerable pressure and kneading is required to express the amylaceous or starchy part of it. Professor Von Buch, in his travels through Norway and Lapland, has fully described the Norwegian _barke bröd_. We find the savages scattered along the coast of the great austral continent mixing up a paste of the bark of the gum-tree with the ants and the other insects, with their larvæ, which they find in it. Ground dried fish and fish-bones have from time immemorial been converted into bread; Arrianus tells us that Nearchus found several nations on the shores of the Red Sea living upon a bread of this description.
It is thus evident that all substances from the animal and vegetable kingdom appear to afford more or less nutriment, provided that they contain no elements unlike the animal matter of the being they are intended to nourish. All others are either medicinal or poisonous. Food may be considered nourishing in the ratio of its easy digestion or solution. Magendie attributes the nutritious principle to the greater or lesser proportion of nitrogen or azote. According to his view of the subject, the substances that contain little or no nitrogen are the saccharine and acid fruits, oils, fats, butter, mucilaginous vegetables, refined sugar, starch, gum, vegetable mucus, and vegetable gelatin. The different kinds of corn, rice and potatoes, are elements of the same kind. The azotical aliments, on the contrary, are vegetable albumen, gluten, and those principles which are met with in the seeds, stems and leaves of grasses and herbs, the seeds of leguminous plants, such as peas and beans, and most animal substances, with the exception of fat.
To this doctrine, it was objected, that animals who feed upon substances containing little nitrogen, and the field negroes, who consume large quantities of sugar, might be adduced as an exception. Magendie replies, that almost all the vegetables consumed by man and animals contain more or less nitrogen--that this element enters in large quantity in the composition of impure sugar--and lastly, that the nations whose principal food consists in rice, maize, or potatoes, consume at the same time milk and cheese.
To support his theory, this physiologist had recourse to various curious experiments on dogs, whom he fed with substances which contained no nitrogen. During the first seven or eight days, the animals were brisk and active, and took their food and drink as usual. In the course of the second week they began to get thin, although their appetite continued good, and they took daily between six and eight ounces of sugar. The emaciation increased during the third week; they became feeble, lost their appetite and activity, and at the same time ulcers appeared in the cornea of their eyes. The animals still continued to eat three or four ounces of sugar daily, but, nevertheless, became at length so feeble as to be incapable of motion, and died on a day varying from the 31st to the 34th: and it must be recollected that dogs will live the same length of time without any food.
The same were the results where dogs were fed upon gum, and butter; when they were fed with olive oil and water the phenomena were the same, with the exception of ulceration of the cornea.
In Denmark, a diet of bread and water for a month is considered equivalent to the punishment of death. Dr. Stark died in consequence of experiments which he instituted on himself to ascertain the effects of a sugar diet.
Muller has justly observed that these experiments of Magendie have thrown considerable light on the causes and the mode of treatment of the gout and calculous disorders. The subjects of these diseases are generally persons who live well and eat largely of animal food; most urinary calculi, gravelly deposits, the gouty concretions, and the perspiration of gouty persons, contain an abundance of uric acid, a substance in which nitrogen is contained in a large proportion. Thus, by diminishing the proportion of azotical substance in the food, the gout and gravelly deposits may be prevented.
The experiments of Tiedemann and Gmelin have confirmed those of Magendie, whose curious observations on the necessity of varying diet I shall transcribe.
1. A dog fed on white bread, wheat, and water, did not live more than fifty days.
2. Another dog, who was kept on brown soldiers' bread did not suffer.
3. Rabbits and guineapigs who were fed solely on any one of the following substances--oats, barley, cabbage, and carrots,--died of inanition in fifteen days; but they did not suffer when these substances were given simultaneously or in succession.
4. An ass fed on dry rice, and afterwards on boiled rice, lived only fifteen days; a cock, on the contrary, was fed with boiled rice for several months with no ill consequence.
5. Dogs fed with cheese alone, or hard eggs, lived for a long time; but they became feeble and lost their hair.
6. Rodent animals will live a very long time on muscular substances.
7. After an animal has been fed for a long period on one kind of aliment, which, if continued, will not support life, allowing it the former customary food will not save it: he will eat eagerly, but will die as soon as if he had continued to be restricted to the article of food which was first given him.
Dr. Paris is of opinion that all that these experiments tend to prove is, that animals cannot exist upon highly-concentrated aliment. Horses fed on concentrated aliment are liable to various disorders, originating from diseased action of the stomach and liver, broken wind, staggers, blindness, &c.
Professor Muller has given an excellent definition of indigestion. "It is a state of the digestive organs in which either they do not secrete the fluid destined for the solution of the aliment, or they are in such a condition of irritability or atony, that by the mechanical irritation of the food, painful sensations and irregular motions are exerted."
But the most curious experiments made on the changes which the food undergoes in the stomach, according to the greater or lesser facility with which it is digested, were those of Dr. Beaumont. This physiologist had the rare opportunity of investigating this subject in a patient of the name of St. Martin, who came under his care in consequence of a gun-shot wound, which left a considerable opening in the stomach, which, when empty, could be explored to the depth of five or six inches by artificial distention. The food and the drink could in this manner be seen to enter it. This enabled him to keep an interesting journal and table, showing the time required for the digestion of different kinds of food, which were taken with bread or vegetables, or both. The following are some of his interesting observations:
_Experiment 33._ At 1 o'clock St. Martin dined on roast beef, bread, and potatoes--in half an hour examined the contents of the stomach, found what he had eaten reduced to a mass resembling thick porridge. At 2 o'clock, nearly all chymified--a few distinct particles of food still to be seen. At half-past four, chymification complete. At 6 o'clock nothing in the stomach but a little gastric juice tinged with bile.
_Ex. 42._ At 8 a.m., breakfast of three hard-boiled eggs, pancakes, and coffee. At half-past eight, found a heterogenous mixture of the articles slightly digested. At a quarter-past ten, no part of breakfast could be seen.
_Ex. 43._ At 2 o'clock same day, dined on roast pig and vegetables. At 3 they were chymified; and at half-past four nothing remained but a little gastric juice.
_Ex. 18_, in a third series. At half-past eight a.m., two drams of fresh fried sausage, in a fine muslin bag, were suspended in the stomach of St. Martin, who immediately afterwards breakfasted on the same kind of sausage, and a piece of broiled mutton, wheaten bread, and a pint of coffee. At half-past eleven, stomach half empty, contents of bag about half diminished. At 2 o'clock p.m., stomach empty and clean, contents of bag all gone with the exception of fifteen grains, consisting of small pieces of cartilaginous and membranous fibres, and the spices of the sausage, which last weighed six grains.
As I have elsewhere observed, various are the theories that have been entertained in regard to digestion, but the experiments of Dr. Beaumont seem to have proved beyond a doubt, that this operation is due to the action of the gastric juice, with which he was enabled to produce artificial digestion. Having obtained one ounce of this solvent from the stomach of his patient, he put into it a solid piece of recently-boiled beef, weighing three drams, and placed the vessel that contained it in a water bath heated to 100°. In forty minutes digestion had commenced on the surface of the meat; in fifty minutes, the fluid was quite opake and cloudy, the external texture began to separate and become loose; in sixty minutes, chyme began to form. At 1 p.m. (two hours after the commencement of the experiment), the cellular substance was destroyed, the muscular fibres loose and floating about in fine small threads very tender and soft. In six hours they were nearly all digested--a few fibres only remaining. After the lapse of ten hours, every part of the meat was completely digested. The artificial digestion by these experiments appears to be but little slower than the natural process--they also demonstrate the influence of the temperature, and the quantity of the solvent secretion. Having obtained from St. Martin two ounces of gastric juice, he divided this quantity into two equal portions, and laid in each an equal quantity of masticated roast beef. One he placed in a water bath at the temperature of 99° Farh.--and left the other exposed to the open air at the temperature of 34°; a third similar portion of meat he kept in a phial, with an ounce of cold water. An hour after the commencement of the experiment, St. Martin had finished his breakfast, which consisted of the same meat with biscuit, butter, and coffee. Two hours after the meat had been put into the phial, the portion in the warm gastric juice was as far advanced in chymification as the food in the stomach; the meat in the cold gastric juice was less acted on, and that in the cold water only slightly macerated. In two hours and forty-five minutes from the time that the experiment was begun, the food in the stomach was completely digested, the stomach empty, while even at the end of six hours the meat in the gastric juice was only half digested. Dr. Beaumont, therefore, having procured 12 drams of fresh gastric juice, added now a portion to each of the phials containing meat and gastric juice, and to a portion of the half-digested food which he had withdrawn from the stomach two hours after the commencement of the experiment, and which had not advanced towards solution. After eight hours' maceration, the portions of meat in the cold gastric juice, and in the cold water, were little changed, but, from the time of the addition of the fresh gastric juice, digestion went on rapidly in the other phials, which were kept at the proper heat, and at the end of 24 hours, the meat which had been withdrawn from the stomach after digestion had commenced, were, with the exception of a piece of meat that had not been masticated, converted into a thickish pulpy mass of a reddish-brown colour: the meat in the warm gastric juice was also digested, though less perfectly, while that in the cold gastric juice was scarcely more acted on than the meat in the water, which was merely macerated. Dr. Beaumont now exposed these two phials containing the meat in cold gastric juice, and meat in water, to the heat of the water bath for 24 hours, and the gastric juice, which when cold had no power on the meat, now digested it; while the meat in the water underwent no change, except that towards the end of the experiment, putrefaction had commenced. The antiseptic properties of the gastric juice were fully demonstrated in several other experiments.
