fattening qualities of decorticated cotton-cake vary exceedingly, 
as will be seen from the following analyses, which I have 
taken at random from the analytical results of a large number 
of cotton-cakes which have passed through my hands during the 
last twelve months.

The preceding analyses show that the proportions of oil in 
decorticated cotton-cake vary from 8| to 22 per cent, and the 
percentage of albuminoids from 38 to 49 per cent. — in round 
numbers. 
A food containing nearly as much as half its weight of 
nitrogenous constituents and only 10 per cent, of oil, pressed 
into a hard cake, is not suitable for herbivorous animals. Such
