bility is largely accounted for, however, by the water-soluble 
alkalies which have been added to the treated cocoas. This fact is 
shown by the percentage of water-soluble material less the ash of the 
water-soluble material, in which determination the untreated cocoas 
vary from 23.54 to 30.11 per cent, with an average of 25.53 per cent, 
while the treated cocoas vary from 19.58 to 28.93 per cent, with an 
average of 24.66 per cent, the untreated cocoas havmg a maximum 
percentage 1.18 higher than the maximum of the treated cocoas, a 
minimum percentage 3.96, and an average percentage 0.87 higher. 
There are eight samples of the alkali-treated cocoas which are less © 
than the minimum of the untreated cocoas.
