_To Make Magic Photographs._--Take, in the first place, an ordinary print--a card-picture, for instance--on albumen paper, beneath the negative in the usual way, and, when sufficiently printed, let it be carefully washed in the dark room, so as to remove all the free nitrate of silver, etc. Now immerse it in the following solution, also in the dark room: saturated solution bichloride of mercury (corrosive sublimate), one ounce; hydrochloric acid, one drachm. The saturated solution is previously prepared by putting into water more bichloride of mercury than it will dissolve by shaking in about twelve hours. The print will gradually be bleached in this liquid, in the ordinary meaning of the word--that is, it will disappear; but the fact is, the print is still there--its color alone is changed, a double salt having been formed of mercury and silver, which is white, as many of our readers, who have been in the habit of intensifying with a mercurial salt, are aware. As soon as the print has quite disappeared, the paper is thoroughly washed and dried in the dark room; it is also preserved between folds of orange-colored paper, in order to keep it from the action of light, for the surface is still in some measure sensitive to light. The bleaching of the print--that is, its conversion into a white salt--is effected more quickly by keeping it in motion in the mercurial solution. As we said before, the print has not been bleached in reality--the substance which originally formed it is still there, together with a new substance, a salt of mercury. But the two salts of silver and mercury may be easily brought out and made visible by several solutions, such as sulphide of ammonium, solution of hydrosulphuric acid; in fact, any of the soluble sulphides, ammonia and hyposulphite of soda. The latter salt is used in preference to the others. Small pieces of blotting-paper, therefore, of the same size as the prints, are cut out and steeped in a saturated solution of hyposulphite of soda and then dried. The magic photographs are packed as before stated, between folds of orange-colored paper; the papers dipped in hyposulphite of soda are the developers, and may be packed between two sheets of common writing-paper. The development of the image is effected in the following manner: place the albumen paper which contains the whitened print on a pane of glass, print side upward; on this lay the dry piece of blotting-paper that has been previously dipped in hyposulphite of soda. Moisten the latter thoroughly, then place over it a pane of glass, and upon this a weight, to bring the two pieces of paper into intimate contact. In a very short time the picture will appear in all its original detail, and of a sepia tone.

_Writing on the Arm._--The conjurer's explanation was a great lesson in "spiritualism." I next asked him to elucidate the trick of writing on the arm. On the occasion of my visit to Mr. Forster, when the raps indicated the second pellet, he required the "spirit" present to write the initials on his bare arm. Mr. Forster placed his arm under the table for a moment, then rested it in front of a lamp burning on the table, and quickly rolled up the sleeve of his coat. The skin was without stain or mark. He passed his hand over it once or twice, and the initials of the names I had written on the second pellet seemed to grow on the arm in letters of crimson. "It's a trick I do every night. It goes with the audience like steam," said the conjurer. "Very simple. Well, suppose a name. What name would you like?" "Henry Clay," I replied. Down went the conjurer's arm under the table. In a few seconds he raised it and exposed the bare forearm without mark upon it. He doubled up his fist tightly so as to bring the muscles of the arm to the surface, and rubbed the skin smartly with his open hand. The letters "H. C." soon appeared upon it in well-defined writing of a deep red color. "There you have it, gentlemen; that's the blood-red writing. Very simple. All you have to do is take a lucifer match, and write on your arm with the wrong end of it. If you moisten the skin with a little salt water first, all the better. Then wet the palm of the other hand, rub your arm with it. Send up the muscles and the blood-red writing will come out. It will fade away in less than no time. If you look under the table, you will see that I have a little piece of pointed wood. I can move my arm under that and write the letters without using the other hand. But that's a trick which wants practice."

_Electrical Psychology._--The most easy and direct mode to produce electro psychological communication is to take the individual by the hand, in the same manner as though you were going to shake hands. Press your thumb on the _Ulnar nerve_, which spreads its branches to the ring and little finger, an inch above the knuckle, and in range of the ring finger. Lay the ball of the thumb flat so as to cover the minute branches of this nerve of motion and sensation. When you first take him by the hand, request him to place his eyes upon yours, and to keep them fixed, so that he may see every emotion of your mind expressed in the countenance. Continue this pressure for a half a minute or more. Then request him to close his eyes, and with your fingers gently brush downward several times over the eyelids. Throughout the whole process feel within yourself a fixed determination to close them, so as to express that determination fully in your countenance and manner. Then place your hand on the top of his head and press your thumb firmly on the organ of Individuality, bearing partially downward, and with the other thumb still pressing the ulnar nerve, tell him--_you can not open your eyes!_ Remember, that your manner, your expression of countenance, your motions, and your language must all be of the most positive character. If he succeed in opening his eyes, try it once or twice more, because impressions, whether physical or mental, continue to deepen by repetition. In case, however, that you cannot close his eyes, nor see any effect produced upon them, you should cease making any further efforts, because you have now fairly tested that his mind and body both stand in a positive relation as it regards the doctrine of impressions. If you succeed in closing the subject's eyes by the above mode, you may then request him to put his hands on his head, or in any other position you choose, and tell him, _you can not stir_ them! In case you succeed, request him to be seated, and tell him, _you can not rise!_ If you are successful in this, request him to put his hands in motion, and tell him, _you can not stop them!_ If you succeed, request him to walk the floor, and tell him, _you can not cease walking!_ And so you may continue to perform experiments involving muscular motion and paralysis of any kind that may occur to your mind, till you can completely control him, in arresting or moving all the voluntary parts of his system.

_How to Make Persons at a Distance Think of You._--Let it be particularly remembered that "Faith" and concentration of thought are positively needful to accomplish aught in drawing others to you or making them think of you. If you have not the capacity or understanding how to operate an electric telegraph battery, it is no proof that an expert and competent person should fail doing so; just so in this case; if faith, meditation, or concentration of thought fail you, then will you also fail to operate upon others. First, you must have an yearning for the person you wish to make think of you; and secondly, you must learn to guess at what time of day or night he may be unemployed, passive, so that he be in a proper state to receive the thought which you dispatch to him. If he should be occupied in any way, so that his nervous forces were needed to complete his task, his "Human Battery," or thought, would not be in a recipient or passive condition, therefore your experiment would fail at that moment. Or if he were under heavy narcotics, liquors, tobacco, or gluttonous influences, he could not be reached at such moments. Or, if he were asleep, and you operated to affect a wakeful mind or thought, you would fail again at the moment. To make a person at a distance think of you, whether you are acquainted with him or not, matters not; I again repeat, find out or guess at what moment he is likely to be passive; by this I mean easy and careless: then, with the most fervent prayer, or yearning of your entire heart, mind, soul and strength, desire he may think of you; and if you wish him to think on any particular topic in relation to you, it is necessary for you to press your hands, when operating on him, on such mental faculties of your head as you wish him to exercise towards you. This demands a meagre knowledge of Phrenology. His "Feeling Nature," or "Propensities," you cannot reach through these operations, but when he once thinks of you, (if he does not know you he imagines such a being as you are,) he can easily afterwards be controlled by you, and he will feel disposed to go in the direction where you are, if circumstances permit, and he is his own master, for, remember, circumstances alter cases. I said, you cannot reach his "Feeling," but only his "Thinking Nature," truly, but after he thinks of you once, his "Feeling Nature," or propensities, may become aroused through his own organization. In conclusion on this topic, let me say, that if you wish the person simply to think of you, one operation may answer; but on the contrary, if you wish him to meet you, or go where you are, all you have to do is to persevere in a lawful and Christian manner to operate, and I assure you, in the course of all natural things, that is, if no accident or very unfavorable circumstances occur, he will make his way towards you, and when he comes within sight, or reaching distance of you, it will be easy to manage him.

_How to Make Large Noses Small._--Dr. Cid, an inventive surgeon of Paris, noticed that elderly people, who for a long time have worn eyeglasses supported on the nose by a spring, are apt to have this organ long and thin. This he attributes to the compression which the spring exerts on the arteries by which the nose is nourished. The idea occurred to him that the hint could be made useful. Not long afterward, a young lady of fifteen years consulted him, to see if he could restore to moderate dimensions her nose, which was large, fleshy, and unsightly. The trait, he found, was hereditary in her family, as her mother and sister were similarly afflicted. This was discouraging, as hereditary peculiarities are particularly obstinate. But the doctor determined to try his method; he took exact measurements, and had constructed for her a "lunette pince-nez"--a spring and pad for compressing the artery--which she wore at night and whenever she could conveniently in daytime. In three weeks a consolatory diminution was evident, and in three months the young lady was quite satisfied with the improvement in her features.

_Jockey Tricks._--_How to make a horse appear as though he was badly Foundered._--Take a fine wire and fasten it tight around the fetlock, between the foot and the heel, and smooth the hair over it. In twenty minutes the horse will show lameness.--Do not leave it on over nine hours.--_To make a horse lame._--Take a single hair from his tail, put it through the eye of a needle, then lift the front leg, and press the skin between the outer and the middle tendon or cord, and shove the needle through, cut off the hair each side and let the foot down; the horse will go lame in twenty minutes.--_How to make a horse stand by his food and not take it._--Grease the front teeth and the roof of the mouth with common beef tallow, and he will not eat until you wash it out; this in conjunction with the above will consummate a complete founder.--_How to cure a horse from the crib or sucking wind._--Saw between the upper teeth to the gums.--_How to put a young countenance on a horse._--Make a small incision in the sunken place over the eye, insert the point of a goose quill and blow it up; close the external wound with thread and it is done.--_To cover up the heaves._--Drench the horse with one-fourth pound of common bird shot, and he will not heave until they pass through him.--_To make a horse appear as if he had the glanders._--Melt four ounces of fresh butter and pour it into his ear.--_To distinguish between distemper and glanders._--The discharge from the nose in glanders will sink in water; in distemper it floats.--_How to make a true pulling horse baulk._--Take tincture of cantharides one ounce, and corrosive sublimate one drachm; mix, and bathe his shoulder at night.--_How to nerve a horse that is lame._--Make a small incision about half way from the knee to the joint on the outside of the leg, and at the back part of the shin bone you will find a small white tendon or cord, cut it off and close the external wound with a stitch, and he will walk off on the hardest pavement and not limp a particle.

_To Bore Holes in Glass._--Any hard steel tool will cut glass with great facility when kept freely wet with camphor dissolved in turpentine. A drill-bow may be used, or even the hand alone. A hole bored may be readily enlarged by a round file. The ragged edges of glass vessels may also be thus easily smoothed by a flat file. Flat window glass can readily be sawed by a watch spring saw by aid of this solution. In short, the most brittle glass can be wrought almost as easily as brass by the use of cutting tools kept constantly moist with camphorized oil of turpentine.

_To Etch upon Glass._--Procure several thick, clear pieces of crown glass, and immerse them in melted wax, so that each may receive a complete coating, or pour over them a solution of wax in benzine. When perfectly cold draw on them, with a fine steel point, flowers, trees, houses, portraits, etc. Whatever parts of the drawing are intended to be corroded with the acid, should be perfectly free from the least particle of wax. When all these drawings are finished the pieces of glass must be immersed one by one in a square leaden box or receiver, where they are to be submitted to the action of hydrofluoric acid gas, made by acting on powdered fluor-spar by concentrated sulphuric acid.

FARMERS' DEPARTMENT.

_How to get New Varieties of Potatoes._--When the vines are done growing and are turned brown; the seed is ripe: then take the balls and string with a large needle and strong thread; hang them in a dry place where they will gradually dry and mature, without danger or injury from frost. In the month of April, soak the ball for several hours from the pulp; when washed and dried, they are fit for sowing in rows, in a bed well prepared in the garden; they will sprout in a fortnight; they must be attended to like other vegetables. When about two inches high, they may be thinned and transplanted into rows. As they increase in size, they should be hilled. In the autumn many of them will be of the size of a walnut, and from that to a pea. In the following spring they should be planted in hills, placing the large ones together,--they will in the second season attain their full size, and will exhibit several varieties of form, and may then be selected to suit the judgment of the cultivator. I would prefer gathering the balls from potatoes of a good kind. The first crops from seeds thus obtained will be productive, and will continue so for many years, gradually deteriorating, until they will need a renewal by the process.

_To Destroy Rats._--Fill any deep smooth vessel of considerable capacity to within six inches of the top with water, cover the surface with bran, and set the vessel in a place most frequented by these pests. In attempting to get at the bran they will fall in and be drowned. Several dozen have been taken by this simple method at a time.

_To Kill Rats in Barn and Rick._--Melt hog's lard in a bottle plunged in water of temperature of 150 degrees Fahrenheit: introduce into it half an ounce of phosphorus for every pound of lard; then add a pint of proof spirits or whiskey; cork the bottle firmly after its contents have been to 150 degrees, taking it out of the water and agitating till the phosphorus becomes uniformly diffused, making a milky looking fluid. The spirit may be poured off on the liquor cooling; and you then have a fatty compound, which, after being warmed gently, may be incorporated with a mixture of wheat flour, or sugar, flavored with oil of rhodium, or oil of anise-seed, etc., and the dough, on being made into pellets, should be laid at the rat holes; being luminous in the dark, and agreeable both to the palates and noses, it is readily eaten, and proves certainly fatal. The rats issue from their holes and seek for water to quench their burning thirst, and they commonly die near the water.

_Rat Poison._--Flour, six pounds; sugar, one pound; sulphur, four pounds; phosphorus, four pounds.

_To Banish and Prevent Mosquitoes from Biting._--Dilute a little of the oil of thyme with sweet oil, and dip pieces of paper in it. Hang in your room, or rub a little on the hands and face when going to bed.

_To Keep Milk Sweet in the Hottest Weather._--Put a spoonful of horse-radish in a pan of milk; this will keep it sweet for several days longer than without.

RECIPES FOR HORSES.

_Blistering Liniment._--Powdered Spanish flies, one ounce; spirits turpentine, six ounces. Rub on the belly for pain in the bowels, or on the surface for internal inflammation.

_Cathartic Powder._--To cleanse out horses in the spring, making them sleek and healthy; black sulphuret of antimony, nitre, and sulphur, each equal parts. Mix well together, and give a tablespoonful every morning.

_Cough Ball for Horses._--Pulverized ipecac, three-quarters of an ounce; camphor, two ounces; squills, half an ounce. Mix with honey to form into mass, and divide into eight balls. Give one every morning.

_Diuretic Balls._--Castile soap scraped fine, powdered resin, each three teaspoonfuls; powdered nitre, four teaspoonfuls; oil of juniper, one small teaspoonful; honey, a sufficient quantity to make into a ball.

_To prevent Horses being Teased by Flies._--Boil three handfuls of walnut leaves in three quarts of water; sponge the horse (before going out of the stable) between and upon the ears, neck and flank.

_To Prevent Botts._--Mix a little wood-ashes with their drink daily. This effectually preserves horses against the botts.

_Liniment for Galled Backs of Horses._--White lead moistened with milk. When milk cannot be procured, oil may be substituted. One or two ounces will last two months or more.

_Remedy for Strains in Horses._--Take whiskey, one half pint: camphor, one ounce; sharp vinegar, one pint. Mix. Bathe the parts affected.

_Another._--Take opodeldoc, warm it, and rub the strained part two or three times a day.

_Lotion for Blows, Bruises, Sprains, etc._--One part laudanum, two parts oil origanum, four parts water ammonia, four parts oil of turpentine, four parts camphor, thirty-two parts spirits of wine. Put them into a bottle, and shake them until mixed.

_Fever Ball._--Emetic tartar and camphor, each half an ounce; nitre, two ounces. Mix with linseed meal and molasses to make eight balls. Give one twice a day.

_Liniment for Sprains, Swellings, etc._--Aqua ammonia, spirits camphor, each, two ounces; oil origanum and laudanum, each, half an ounce. Mix.

_Lotion for Mange._--Boil two ounces tobacco in one quart water: strain; add sulphur and soft soap, each, two ounces.

_Purgative Ball._--Aloes, one ounce; cream tartar and castile soap, one quarter of an ounce. Mix with molasses to make a ball.

CONFECTIONERS' DEPARTMENT.

_Ginger Candy._--Boil a pound of clarified sugar until, upon taking a drop of it on a piece of stick, it will become brittle when cold. Mix and stir up with it, for a common article, about a teaspoonful of ground ginger; if for a superior article, instead of the ground ginger add half the white of an egg, beaten up previously with fine sifted loaf sugar, and twenty drops of strong essence of ginger.

_Ginger Lozenges._--Dissolve in one-quarter of a pint of hot water half an ounce of gum arabic; when cold, stir it up with one and a half pounds of loaf sugar, and a spoonful of powdered ginger, or twelve drops of essence of ginger. Roll and beat the whole up into a paste; make it into a flat cake, and punch out the lozenges with a round stamp; dry them near the fire, or in an oven.

_Peppermint Lozenges._--Best powdered white sugar, seven pounds; pure starch, one pound; oil of peppermint to flavor. Mix with mucilage.

_Peppermint, Rose or Hoarhound Candy._--They may be made as lemon candy. Flavor with essence of rose or peppermint or finely powdered hoarhound. Pour it out in a buttered paper, placed in a square tin pan.

_To Clarify Sugar for Candies._--To every pound of sugar, put a large cup of water, and put it in a brass or copper kettle, over a slow fire, for half an hour; pour into it a small quantity of isinglass and gum Arabic, dissolved together. This will cause all impurities to rise to the surface; skim it as it rises. Flavor according to taste.

All kinds of sugar for candy, are boiled as above directed. When boiling loaf sugar, add a tablespoonful of rum or vinegar, to prevent its becoming too brittle whilst making.

Loaf sugar when boiled, by pulling and making into small rolls, and twisting a little, will make what is called little rock, or snow. By pulling loaf sugar after it is boiled, you can make it as white as snow.

_Common Twist Candy._--Boil three pounds of common sugar and one pint of water over a slow fire for half an hour, without skimming. When boiled enough take it off; rub the hands over with butter; take that which is a little cooled, and pull it as you would molasses candy, until it is white; then twist or braid it, and cut it up in strips.

_Fine Peppermint Lozenges._--Best powdered white sugar, 7 pounds; pure starch, 1 pound; oil of peppermint to flavor. Mix with mucilage.

_Everton Taffee._--To make this favorite and wholesome candy, take 1½ pounds of moist sugar, 3 ounces of butter, a teacup and a half of water and one lemon. Boil the sugar, butter, water, and half the rind of the lemon together, and when done--which will be known by dropping into cold water, when it should be quite crisp--let it stand aside till the boiling has ceased, and then stir in the juice of the lemon. Butter a dish, and pour it in about a quarter of an inch in thickness. The fire must be quick, and the taffee stirred all the time.

_Candy Fruit._--Take 1 pound of the best loaf sugar; dip each lump into a bowl of water, and put the sugar into your preserving kettle. Boil it down and skim it until perfectly clear, and in a candying state. When sufficiently boiled, have ready the fruits you wish to preserve. Large white grapes, oranges separated into small pieces, or preserved fruits, taken out of their syrup and dried, are very nice. Dip the fruits into the prepared sugar while it is hot; put them in a cold place; they will soon become hard.

_Popped Corn._--Dipped in boiling molasses and stuck together forms an excellent candy.

_Molasses Candy._--Boil molasses over a moderately hot fire, stirring constantly. When you think it is done, drop a little on a plate, and if sufficiently boiled it will be hard. Add a small quantity of vinegar to render it brittle and any flavoring ingredient you prefer. Pour in buttered tin pans. If nuts are to be added strew them in the pans before pouring out the candy.

_Liquorice Lozenges._--Extract of liquorice, 1 pound, powdered white sugar, 2 pounds. Mix with mucilage made with rosewater.

_Fig Candy._--Take 1 pound of sugar and 1 pint of water, set over a slow fire. When done, add a few drops of vinegar and a lump of butter, and pour into pans in which split figs are laid.
