Not all the uric acid formed in the body may be expected to appear, as such, in the excretions, for much of it is probably converted into urea; the uric acid of the urine has perhaps reached the kidneys without passing through the liver. Hippuric acid is a nitrogenous waste product which appears in human urine in small quantities only; it is more abundant in the urine of the hcrbivora, and, in the case of man, may be increased by eating vegetables, more especially fruits, which contain aromatic substances that are oxidized in the body, with the formation of ben-zoic acid. Hippuric acid appears in the urine, to a certain extent, even during starvation, and cannot therefore be entirely derived from food; aromatic compounds must originate in small quantities from the metabolism of proteids, and be converted into benzoic acid. The benzole acid, whether it be formed from food or from body proteids, is combined by the kidney with glycocol to form hippuric acid, and thus excreted. It appears, then, that urea is not an immediate product of proteid metabolism, but that intermediate substances are formed, such as creatin, ammonium salts, possibly amido-acids, etc. It is certain that glycocol may be formed in the body, for the administration of ben-zoic acid results in the appearance of hippuric acid in the urine. As in the case of the nitrogenous, so in the case of the carbonaceous half of proteid, decomposition into the final waste products, carbon dioxid and water, is not immediate. Indeed, after a meal consisting of proteids, the excretion as urea of an amount of nitrogen corresponding to that administered...
