Obviously, in order to ascertain the percentage yield of the 
sugar introduced, it was necessary to ascertain the quantity of 
available sugar in the process before and after the run. The 
data in Tables III and IV give this information as “available 
sugar,” and the values indicated signify the yield of 100-per-cent 
sugar which the amount of sugar in process was capable of 
producing on a basis of 40-per-cent molasses.

The difference between 3,455 and 1,973, or 1,482 kilograms, 
represents the amount of 100-per-cent sugar extracted from 
the sugar in the process which was not introduced during the 
run. Therefore, this difference of 1,482 must be deducted from 
the total yield of 12,866 kilograms, leaving 11,382 kilograms as 
actual yield from the sugar introduced during the run. The 
figures in Table V summarize the results so far obtained.
