th.e volumes of theliquids displaced by it are inversely proportional totheir specific gravities. Instead of a rod constructed as described, ah instru-ment called a hydrometer is generally employed to takeadvantage of this principle in determining the specificgravities of liquids. The common… … SPECIFIC GRAVITY. 151 liquid (Fig. 122).
