It is a powerful base, able to drive ammonium out of its combinations, and may be recognised by] its crystalline form, which belongs to the oblique rhombic system as shown in Fig. 78. Fig. 78.—Kreatinin. To detect the presence ofkreatinin add to the urine a few drops of pale red solution of nitro-prusside of sodium, and then, drop by drop, a dilute solution of caustic potash, when a ruby-red colour is struck, varying in intensity according to the amount of kreatinin present. The colour soon passes into a straw-yellow tint. The quantity of kreatinin in the urine of twenty-four hours varies in health from -5 gramme to 1 gramme, or from 7 to 15 grains. It is derived from the kreatin of the
