Physical laboratory experiments : mechanics, optics and heat. rst, whencompletely filled with water or with the water adjusted tosome reference mark; and second, when the flask containsboth substance and water, the total volume being againadjusted the same as before. From these two weights, to-gether with that of the substance dry, the weight of thewater displaced by the immersed solid can be at once deter-mined. The accuracy of the determination depends on theprecision with which the contents of the flask can be adjustedsuccessively to the same volume. 50 PHYSICAL LABORATORY EXPERLMENTS In Fig. 14 are shown three of the best forms of specificgravity bottles in general use. All are provided with care-fully ground stoppers. The stopper of A has a capillary boreand the water is adjusted so as to com-pletely fill the flask and stopper. In B andC the liquid is adjusted to a reference marketched on the narrow stem. C is providedin addition with a sensitive thermometer,ground to fit the neck of the flask, for indi-cating the temperature of the
