    and expose them to the same high temperature. After they have been made anhydrous let each be dissolved separately in 572 grains of pure water, when it will be found that the different solutions remain of the same hulk as the water was previously to the salt being dissolved in it, and each solution would fill a bottle capable of containing only 572 grains of pure water. The first solution wrould con¬ sist of 572 grains of water + 52 grains of solid matter = 624 grains ;—the second solution 572 grains of water + 104 grains of solid matter =676 grains;—and the third 572 grains of water + 156 grains of solid matter = 728 grains. But if the Sulphate of Magnesia was taken in its ordinary state, and 100 grains dissolved in 572 grains of pure water, the water of crystallization in the salt would increase the hulk of the water by 48 grain measures, and the solution would consist of 572 + 48 grains of water + 52 grains of solid mat¬ ter = 672 grains—a solution of 200 grains of the same salt would consist of 572 + 96 grains of water +104 grains of solid matter = 772 grains— and a solution of 300 grains of the salt would con¬ sist of 572 + 144 grains of water +156 grains of solid matter = 872 grains. The solid matter would go into the pores ol the water.
