Without giving the detailed analytical data, it will suffice 
for our purpose to indicate the changes in the form of pounds 
of constituents in 50 gallons of dilute mixture with and with- 
out addition of lime. Four different concentrated solutions of 
the lime-sulphur wash were diluted and treated in the manner 
indicated. The solutions used were free from sediment. In the 
table following, we give the results in such form as to show 
what changes occurred in the soluble sulphur compounds.

In Table XI the amounts of sulphur in various compounds 
is given in pounds for 50 gallons of diluted solution, first with- 
out lime and then after addition of lime in each case. The 
mixtures contained in any given case the same amount of total 
sulphur, of course, before and after treatment with lime, the 
amount of sulphur in the different experiments varying from 
13.10 to 14.40 pounds in 50 gallons of diluted mixture. There 
is also given in each case the amount of sulphide sulphur, 
thiosulphate sulphur and free sulphur, or sulphur in sediment, 
before and after treatment with lime. We also give the per- 
centage of total sulphur in these three different forms before 
and after treatment with lime. In the last column, we give the 
ratio of calcium to sulphide sulphur before and after treatment 
with lime. To illustrate, we take experiments 19-a and b. In
