Excerpt from The Journal of Physical Chemistry, 1910, Vol. 14 The bath was regulated to within C. The method Of procedure was as follows. The picnometers were filled with the solution to be measured at a temperature somewhat lower than 2 Fine rubber tubes, filled with the solution, were then drawn over the capillaries and the whole immersed in the bath with the ends of the rubber tubes coming out of the water. It was found that the temperature Of the solu tion became constant within half an hour. The rubber tubes were then removed, allowing only the capillaries to come above the surface Of the water. The drops were carefully flicked Off, the stoppers put on, the whole apparatus was carefully wiped, and the picnometer hung in the balance case. The water used in this research was distilled from a solu tion Of alkaline permanganate through a block-tin condenser and then redistilled immediately before use. Standing in glass a few days increased sensibly the specific gravity. The air was sucked out Of the solutions by connecting the picnom eter with the vacuum pump. Kahlbaum's dry chemicals and Baker 81 Adamson's acids were used without further purification. A solution Of the material to be investigated was made up stronger than required and analyzed carefully. From these stock solutions there were prepared by dilution the solutions actually employed in the measurements.
