"Now, these several nitrogenous and non- nitrogenous constituents of the feod are con- stantly imdergoing change and destruction in ministering to the several necessities of the living animal organisation — as the growth, substance, and waste of the body, its heat, electricity, and muscular force ; and hence the necessity for a frequent supply of food. " The mineral constituents of the body arc not less necessary than the albuminates, fat, and the carbo-hydrates, and equally require to bo renewed in the food consumed. Thus, sulphur and phosphorus are constantly present, com- bined chiefly with the albuminates. Phosphate of lime is found principally in the bones, teeth, and cells and tissues ; phosphate of potash in the tissues and cells ; chloride of sodium in the hquids ; iron in the blood ; and, lastly, carbonic acid, lactic, tartaric, acetic, and some other acids, which are converted in the system into carbonic acid, are requisite to maintain the alkalinity of the body, the loss of which gives rise to scurvy. "Again, the imbibition of a large quantity of water daily is likewise a necessity, in order to endow many of the constituents of the food — especially the albuminates — with certain physical jiroperties, to render them plastic, soluble, or the more readily reducible to a state of solution ; thus aiding absorption, nutrition, and elimination." There is thus, we see, between the composition of the body and the food consumed, whether animal or vegetable, the closest possible re- semblance. Having now seen what kinds of food are needed to keep the body in health, we come to look at the quantities required. The quantities of course vary according to age, weight, and muscular exertion, but it has been determined, by numerous independent inquiries, that the food daily consumed by an adult man of average weight — 140 pounds — in moderate work, should contain about the following quantities of the several classes of food, the figures given being PRO ( 656 ) PRO those of Molesholt, quoted by Parkes in his valuable work on " Practical Hygiene." Di-y Food. Ounces Nitrogen. Carbon, and Grains. Grains. Grains.

" But water, to the e.xtent of between fifty and sixty-nine per cent., is contained in the food consimied, raising the amount to about forty ounces." Now, nearly the whole of the nitrogen and carbon contained in the chief articles of our food may be thus divided and distributed : — T T. AT J. S 16 oz. less one-fifth bone.
