58 SCIENTIFIC PRESS. [January 27, 1872. om ESTIC Economy. Animal Food. A late number of the Galaxy has an artiele, by Dr. C. Draper, upon animal food for man. The Doctor does not agree with the vegetation philosophy. We do not kuo¥ but the question of meat or no meat will be one of debate while the world stands. Concerning the influence of climate upon diet, Dr. Draper speaks as follows: a **Gustom and religion have, it is trne, a certain influence over the diet of a nation, put the habits of a people in this respect are, to a great extent, under the control of climate. The inhabitant of a torrid region delights in the fruits and succulent vegetables with which nature bountifally supplies him, and does not care to undergo the fatigue and exertion necessary to obtain animal food, when luscious fruit are ready to fall into his mouth. He lives surronnded by 2 warm, moist atmosphere, he does not require munch heat-making food; the very air is enervating, and why should he exert himself when there is no necessity ? The dwellers in arctic regions, on the contrary, must burn away rapidly in order to keep the temperature of his body at the point required to sustain the processes of life. Animal food therefore becomes the urgent requirement of his existence, and since fat furnishes the greatest amount of heat ina given bulk, he seeks greedily for the blubber of the seal or whale, and a glass of oil is to him far more desirable than the choicest wine of a Comet vintage. “Between these extremes we find the inhabitant of the temperate zone, who, while he declines to partake of the grosser food of his northeru neighbor, agrees with him in his craving for flesh of all kinds, aud prizes especially venison and every species of game. At his table the fruits and vegetables of the southerner also have their place. He occupies the position that nature has intended for his race. He is an omniverous animal and with such a diet, and under favorable skies reaches the highest development of which his kind is capable. It is interesting to notice that when the system has become accustomed to a mixed diet, a total abstinence from either animal or vegetable food causes the disease known as scurvy. It is a popular error to suppose that this condition is the result only of a want of vegetable food. This error has arisen from the fact, that, heretofore, in long voyages, vegetable food has been deficieut in quantity, but we now know that a species of scurvy may arise from a deficiency in the supply of animal food.” Hard and Soft Boiled Eggs. It is understood that eggsare more easily digested if ‘“‘ rare” than “well” done; but which portion of the egg resists digestion —the ‘f white,” which is nearly pure albumen, or the yolk? Lately experiments have been made in this direction with ample opportunity of demonstrating . that healthy gastric juice, which thestomach seeretes for purposes of digestion, will not act readily on firmly coagulated white of egg, eveuif cut in pieces not larger than ordinary peas (and that is as fine as people usually chew their food!), while it acts with facility npon the more brittle yolk. The reason is that the coagulated albumen is very compact and tenacions, and would need to be ‘* ground to powder” to accept the chemical affinities of the gastric jnice. Pour intoa basin boiling water sufficient to cover the eggs, put the eggs into the water and let them remain 10 or 15 minutes, according to circumstances and your own taste; keep the water nearly up to boiling temperature, but don’t boil the eggs. Fresh eggs will cook more quickly than old ones, and of course small ones quicker thau large ones. By this process you will find the yolks well cooked, while the white is left in a condition to digest readily. Morns.—Iu India, both upholsterers and saddlers badly tronbled with moths in their work, especially in the rainy seaSou; and the npholsterers in that conntry follow a series of simple rules by which they entirely avoid the ravages of these pests. They never put on & burlap or cotton covering withoutfirst steeping it in a solution of sulphate of copper, made by dissolving about one ouuce in one gallon of boiling water, aud then quickly drying the material iu the sun or by ahot stove. For over “coverings, especially if of wool, a solution colorless alcohol is frequently used with good effect. The boiling solution of sulphate of copper is often applied to a floor previous to laying a mat or carpet, and inyariably under heavy articles of furniture. Hollow Measure in the United States. The following data with regard to measurements will oftentimes be found convenient for reference: A barrel contains 40 gallons of 321 cubic inches, or 9,240 cubie inches. The normal bushel is the Winchester; this ought to have the diameter in the clear of 1814 inches, to be 5 inches deep, and to have the capacity of 9.25x9.25x 3.14168, or about 2,15014 cubic inches. Abox 24 inches square and 16 inches deep has a capacity of 9,216 cubic inches, or nearly a barrel. A box 1794x15x8 inches contains 2,180 cubic inches, or nearly a bushel. A box 1414x10x74 inches contains 1,075 cubie iuches, or exactly a half bushel. A box 8x8x8 5-12 inches contains 538 cubie inches, or almost exactly a peck or quarter bushel. A box 7x8x4}¢ iuches contains 231 cubic iuches, or 2 gallon. <A box 6x6x824 inches contains 117 cubic inches, or nearly abalf gallon of 115% cubic inches. A box 454x3% inches contains 56 cubic inches, or nearly a pint or quarter gallon (5734 cubic inches.) A New Use for Fresh Eggs. Mr. John Murphy of this city—a gentleman of intelligence and close observation —recently made to us some interesting statements in regard to the value of fresh eggs in affording nourishment to weak animals, that are worth rememberiug by all farmers. He remarked that he had known a young colt which to all appearances was nearly dead, the breath of life being barely perceptible, to be quite instantly revived by giving it one or two fresh eggs. The same results, in several cases to which he was knowing, have followed the administering of eggs to weak calves, and also to feeble and chilled lambs. A remedy so simple, so easy at haud and so effectual in the cases mentiened—which often occur with calves and lambs—should be remembered by all our readers. CornsraLx Syrup.—S. W. Bloom, of Broomstown, Ind., has made frorh common cornstalks a syrup superior in flavor to sorghum, though there was a sorghum flavor discernible. The yield is nearly equal, per acre, to that of sorghum, and does not interfere with the production of green corn for market, from the same stalk. Mechanical Hints. Fine Green Broyze.—First boil the work in a strong solution of potash to get off all the old lacquer and grease; next wash in clear water, after that let the work stand a day or two in a weak solution of nitric acid, then take out, wash, and dry; then coat the article with some good black lead. Polish until you have a good black glossy surface; then put on your yellow lacquer, which, put on a black surface, is your green bronze. Warerrroor Grun.—A glue that will resist both fire and water may be prepared by mixing a handful of quicklime with four ounces of linseed oil, thoroughly levigated, then boiled to a good thickness, and kept in the shade, on tin plates,to dry. Itmay be rendered fit for nse by boiling it over a fire in the ordinary manner. American Furniture Asroap.—During the week ending Dec. 12th, there was exported from the port of New York five cases of redwood to Stittin; two pianos and seven huudred and fifty fine packages of furniture, valued at $9,932, to Peru; eleven boxes of furniture and one hundred logs of maple to London; seven packages of furniture to the British West Indies; twenty-five logs of maple to Havre; twentynine packages of furniture, valued at $1,510 to Hayti; fourteen cases of furniture ‘to Central America; eleven packages of furniture to New Grenada; three packages of furniture to Venezuela, and_ thirty-four packages of furniture to Brazil. Ou the 14th of the same month, eight cases of furniture were shipped from New York to Constantinople; fifteen cases to Havaua; nineteen packages of furniture to Poiut a Petre; one hundred cases of furuiture to Rio Janeiro; seveu packages of furniture, one piano aud eight cases of oil cloth to Vera Cruz. Ou the 16th, one hundred cases of furniture, shipped from New York to Bombay, and ten hundred and sixty seven packages of corrosive snblimate dissolved in patent . of furniture to Sydney.
