After all bubbles of gashave disappeared the eudiometer is transferred to a cylinder filledwith water and thoroughly immersed. After twenty to thirtyminutes the level of the liquid in the tube and that of the outsidewater are equalized and the reading taken. The temperature ofthe water being likewise noted, the volume of the gas is correctedand the corresponding amount of urea calculated. Squibbs Method.—This method, like that of Doremus, may behighly recommended to the practitioner for its simplicity. Theapparatus (Fig. 90) consists of two ordinary medicine-bottles, A and Fig. Squibbs ureometer. B. In A the nitrogen is evolved. B is closed by a doubly perforatedrubber stopper, a straight tube passing through the upper apertureand connecting with the bottle A. Another tube, bent downwardand carrying a clamp, as seen in the figure, leads to a graduatedcylinder, E. B contains a sufficient amount of water for the benttube to dip into; 25 to 30 of the hypobromite solution and a CHEMISTRY OF THE URINE. 363 small tube containing 2 of urine (diluted if necessary, accordingto the specific gravity) are placed in A, the clamp at E being rubber stopper is now firmly inserted and E opened, when afew drops of water, which may be disregarded, will escape. Thegraduated cylinder is then placed beneath the outflow-tube and thebottle A inclined. The nitrogen collecting in B displaces its ownvolume oi water, which flows ou
