Since it is admitted that the above strengths (a) and (b) 
have given satisfaction in field trials, I have taken these 
strengths as a standard and have calculated the dilution 
necessary in the case of these lime sulphur solutions as 
made by the various formule stated, so that the resultant 
mixtures shall contain the same number of pounds of sul- 
phur per 100 gallons as do the standards chosen, namely 
one volume of the highly concentrated lime-sulphur solution 
with ten volumes of water for winter use, and one volume 
of the highly concentrated lime-sulphur solution with fifty 
volumes of water for summer use. 
These are set forth in Table IV which also gives the 
Specific gravity and degrees Baumé. Underneath will be 
found a table giving the amount in pounds per 100 gallons 
of sulphur in the various forms of combination present in 
these mixtures.
