The data indicate that the specific gravity in the mixture of 
Solution and sediment increased with the increased amount of 
lime used. In the clear solution, the tendency of the specific 
gravity is to increase with increased amounts of lime, indicat- 
ing a greater concentration of solution as noticed later. 
(2) Composition of solution.—In the table following, we give 
the percentages of the important constituents of the clear solu- 
tion. The percentage of calcium in combination with sulphides 
is calculated by subtracting from the total amount of calcium 
in solution the amount of calcium in combination as thiosul- 
phate.
