control diets of com meal or soybean meal and molasses instead of cot¬ 
tonseed meal. On cottonseed products the rabbits showed varying be¬ 
havior, from being made sick (diarrhea) on one or two doses of raw kernels 
to consuming the ether-extracted kernels without noticeable harm for 75 
to 200 days. Toward various cottonseed meals the rabbits also showed 
varying reactions. Some meals not thoroughly cooked were refused in 
less than a week, while other meals were eaten for more than three or 
four weeks before the rabbits became sick. The same general results 
were observed in these as in the rat experiments. The ether-extracted 
raw kernels were least toxic of all, but the rabbits were rather sensitive 
even to them, and occasionally became sick after long feeding periods 
when fed at the rate of 1 per cent of body weight daily, the usual rate of 
feeding. This is apparently due to incomplete extraction of the kernels 
(Table II).
