By observa-tion of the position of equilibrium of an empirically graduated instrumentcalled an hydrometer, when immersed in the material. I. This method is carried out with the pycnometer, or specific gravitybottle, shown in Fig. 325. The weight of the bottle when clean and dry isobtained. It is then filled with distilled water, the ground glass stopper isinserted, and the excess water forced out through the side tube. It is wellto reduce the temperature of the water, or other material, below the tem-perature at which the observation is to be made. On gradually reachingthis temperature, a little liquid wiU exude from the side tube, which may beremoved with a piece of absorbent paper. The c
