Two adult sheep were used similarly; one was fed i pound of commercial 
cottonseed meal daily, the other the same quantity autoclaved. The 
sheep were kept on green pasture for 90 days, but since no ill effects 
were noted in either at the end of that time, the experiment was discon¬ 
tinued. This experiment was repeated, feeding two sheep, as in the previ¬ 
ous experiment, except that the animals were kept in a dry lot and fed 
dry alfalfa and prairie hay as roughage. At the end of 90 days these 
sheep showed no ill effects. 
These experiments seem to show (1) that autoclaving cottonseed meal 
destroys the poison peculiar to it and (2) that different lots of the meal con¬ 
tain different amounts of the poison. Further work will have to be done 
to determine whether it is the high temperature that destroys the poison 
or oxidation by the oxygen of the air during the drying.
