Nov. is, 1915 Gossypol , the Toxic Substance in Cottonseed Meal 287 
(7) Methods for rendering cottonseed kernels nontoxic depend upon 
extracting the gossypol or changing it to physiologically inert forms by 
oxidation or by precipitation. 
(8) The smallest amount of gossypol administered intraperitoneally 
by us and found fatal to rabbits was 0.24 gm. of crystalline gossypol 
acetate per kilo of live weight.
