It will be seen that this refuse material contained rather more than 
20 per cent, of oil, and in round numbers 15 per cent, of albuminous 
compounds, and therefore possessed valuable feeding properties. 
3. Cotton-Cakc. — The accompanying- woodcut (Fig. 14) re- 
presents the appearance of cotton-seed 
under the microscope. Cotton-seed can be Fig. 14. — Cotton-seed, 
readily identified by the reddish-brown external coat, with 
colour and peculiar structure of its husks. fibres. 
Undecorticated cotton-cake is full of ^rfffi"^^^ 
husk^, inasmuch as most samples of cot- jj^M i j^W"' 
ton-seed contain over 40 per cent, and 
some rather more than 50 per cent, of I^^M iSHSKt 
husk. It has a greenish colour when .y. 
fresh, and turns brown when the cake \jLig em^^^::j,Mim 
is kept for some time. Decorticated 
cotton-cake is made from the shelled seed 
or kernel, which varies in size in different 
samples, and is seldom larger than a ^ uo Diameters, 
large raisin pip. 
The following average analyses show that decorticated cotton- 
cake is very rich in albuminous compounds, in which respect it 
closely resembles decorticated earth-nut-cake. It differs from 
the latter by being much richer in oil, and on the whole is pre- 
ferable to earth-nut-cake as a feeding material : —
