On the preservation of meat by the use of chemical agents, or antiseptics, much ingenuity has been expended by scientific men. The best known antiseptic is chloride of sodium, or common salt, which has been employed for the preservation of animal substances from a very early period. It is likely always to remain in. use, either simply or in conjunction ^vith an; after-process of drj-ing or smoking, or with both combined. The fact is that many substances treated with conmion salt are extremely tasty and palatable — ham and bacon, for example — and the cost of the process is exceedingly trifling. It should be remembered, however, that salt by itseK is only a temporary preserva- tive agent, and is dietetically to be objected to on the ground that it extracts the soluble con^ stitiT^ntf, of meat, makes it hard and indiges- tible, and thus deprives it of its stimulating and nutritive constituents. From the eating of large quantities of salt meat without the proper quantity of vegetables to coimteract its effects, it is well known tliat scorbutic (U.-eases ensue. Besides common salt, other saline substances have been employed for the preservation of PRE (650) PRE meat ; for example, saltpetre, acetate of am- I monia, sulphate of potash, and muriate of ammonia. The smoking of meat or fish by exposure to the vapour of peat, wood, Sec, is chemically subjecting them to the action of the creosote of the empyreumatic oil of the smoke. The preservation of provisions by means of salt, sugar, spices, vinegar, spirit, and fumiga- tion by burning wood, have the drawback of i being partly chemical additions to food, and also of inducing chemical changes, which, to a certain extent, influence the digestibility of the i article. Salt, also, as we have hinted, draws 1 out from the meat some of its chief nourishing constituents. Liebig, in his " Chemistry of Food," remarks: — "It is universally knowTi that in the salting of meat the flesh is rubbed and sprinkled with dry salt, and that where the salt and meat are in contact a brine is formed, amounting in bulk to one-third of the fluid contained in the raw flesh. I have ascertained that this brine contains the chief constituents of a concentrated soup, or infu- sion of meat, and that therefore, in the process of salting, the composition of the flesh is changed, and this, too, in a much greater degree than occurs in boiling. In boiling, the highly nutritious albumen remains in the mass of the flesh ; but in salting, the albumen is separated from the flesh ; for when the brine from salted meat is heated to boiling, a large quantity of albumen separates as a coagulum.
