ITS SEEDS AS THEY APPEAR IN COMMERCE. 25 



Cacao-red occurs as a coloring matter in small amount. It is 

 rendered dark by alkalies. 



Theobromine, the active principle of the cocoa-bean, consti- 

 tutes less than one per cent of the weight of the seeds, but it 

 varies greatly in amount in different seeds, ranging from -^^ of 

 one per cent in some, to a trifle over one per cent in others. 



The ash left on completely burning cocoa-beans is not far from 

 four per cent. Its composition is substantially that of the ash 

 of seeds of other plants. 



Cocoa-butter, or oil, constitutes not far from fifty per cent of 

 good cocoa-beans. The oil is remarkable for its freedom from 

 rancidity and its very bland character. Its uses are innumerable.
