386 REPORT OF THE CHEMIST OF THE 
preparations under discussion that a lime was used containing 
considerable magnesium compounds and other impurities. 
When we consider the character of the compounds found in 
the sediment, there is no reason whatever for believing that 
the value of the mixture is peculiarly enhanced by the presence 
of this insoluble matter; but that, on the other hand, the value 
to the fruit-grower is lessened, because the amount of soluble 
sulphides contained in a barrel is considerably less by reason 
of the presence of the sediment. To what extent the sediment 
constitutes a part of 50 gallons of mixture may be seen from 
the table following:

In sample F the sediment constitutes 20 per ct. (by weight) 
of the contents of a 50 gallon barrel. Such material is 
obviously not economical to purchase when clear solutions, 
free from sediment, containing higher percentages of soluble 
sulphides, are on the market at the same price.
