The only practical difference of cost in the foods of the two lots 
is that between the two kinds of cotton-cake, and accordingly we may 
briefly put it that the gain of 2/. lis. on the four bullocks fed with 
decorticated cotton-cake was obtained at the extra cost of 5s. 9c?. 
(5^. 14s. 9(?. minus 5/. 9s. OcZ.), or a net gain of 21. 5s. "id. resulted 
from the use of 1918 lb. of cake, equivalent to a gain of 21. 12s. \Qd. 
on <he use of one ton of cake. Thus, taking only the feeding value 
of the cakes into account, and omitting all reference to manurial 
value, it will be seen that, according to this experiment, decorticated 
cotton-cake may cost 53s. per ton more than undecorticated cotton- 
cake and yet produce an equal feeding effect. 
I have calculated, further, the chemical composition of the 
average daily diet ii^ either ease,
