pig receiving cotton seed meal notified us that it was 

 time for the experiment to close. The pigs in the other 

 pens remained healthy. All were butchered as soon as 

 the exj>eriment was stopped, and samples of fat were 

 taken and rendered into lard. 



Up to the tim|e of the death of one pig and the evident 

 unthriftiness of another, the pigs in Lot V, averaging at 

 the middle of the period 59.4 pounds per head in weight, 

 had each consumed since the seventh of November 5.4 

 pounds of cotton seed meal. This is equivalent to saying 

 that toxic effects were evident when for each 100 pounds 

 of average live weight 9.2 of cotton seed meal had been 

 consumed. During the experiment proper the average 

 daily consumption of cotton seed meal was .25 of a 

 pounds per 100 pounds of live weight It will be re- 

 called that when the same mixture was fed in an earlier 

 experiment to somewhat larger, but young shoats, the 

 daily consumption of .41 of a pound per 100 pounds 

 live weight resulted fatally. In a still earlier experi- 

 ment with still larger shoats, cotton seed meal was 

 consumed at the rate of .61 of a pound daily per 100 

 pounds of live weight, for 35 days; no immediate con- 

 spicuous injury resulted, and observations on subse- 

 quent effects were prevented by the disposition made of 

 the pigs.
