while that for urea is CH N,0. But regarding the two
bodies as derivatives of the double atoms of water and
ammonia respectively, or as the hydrate and amide of
carbonyl, these formulæ become (CO)”H,02, corresponding
to H2O2, and (CO)"H N, corresponding to H N, respec-
tively. Accordingly, the representation of urea as a com-
pound of carbonic acid and ammonia with elimination of
water, or as a variety of carbonic acid in which certain
elements of water are replaced by the corresponding
elements of ammonia, is shown in these almost identical
equations :
