382 Report oF THE CHEMIST OF THE 
approximate relative cost of each pound of combined sulphur 
in solution on the basis of ten doliars for 50 gallons. In a so- 
lution containing about 24 per ct. of combined sulphur, each 
pound of sulphur costs 8 cents when 50 gallons sell for ten 
dollars. We can, therefore, estimate what the relative cost of 
50 gallons is when the solution contains more or less sulphur 
than about 24 per ct. The various data here referred to are 
presented in the following table. These figures are given for 
sake of making comparison and not with any reference to 
actual market values.

COMPOSITION OF COMMERCIAL PREPARATIONS. 
In Table XV are given the percentages of sulphur in different 
forms and of calcium in combination as sulphides which were 
found to be present in the samples examined. In the case of 
samples E—G, the percentages are based on the whole mixture, 
sediment and solution. In the other cases there was no ap- 
preciable amount of sediment.
