Urea [CO(]SrH2)2].—Urea is of importance to the medical man because its amount is dependent on the amount of the metabolism of the proteid constituents of the food and those of the body. Its sudden diminution in the urine of a case of Bright's disease (the diet being constant) is of far more dan- gerous import than an increase of albumin. It is as well to become acquainted with its general characters first. It is the diamide of carbonic acid (COg) or carbamide.* From urine it *Altliougli this is now denied, for although isomeric with carbamide the reactions are not those of an amide (Allen.)
