COMMERCIAL COCOA 



CALCULATED ON THE HUSKED SAMPLES 



As previously mentioned some buyers take into con- 

 sideration the proportion of shell present in estimating 

 the value of cocoa. 



The proportion of the shells and the mean \veight of 

 the beans of different cocoas have been determined 

 by Brayning (Journal d' Agriculture Tropicale, p. 31, 

 July 1901), as follows : 



The varying proportions of particular constituents, 

 which different investigators have found in cocoa from 

 the same country of origin, are probably due to the 

 different methods of cultivation and preparation adopted, 

 as well as to the examination of more than one variety of 

 beans.
