BULLETIN 666, IT. S. DEPARTMENT OF AGRICULTURE. 



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 having 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.
