Fig. 5 .—Graphs showing the effect of various diets on the growth of pigs. Figs fed on peanut meal and 
soybean meal show a decided and regular gain in weight, while those fed with cottonseed meal supple¬ 
mented by other feed made good gains only during the early part of the feeding period. The toxicity of 
the meal is shown by the death of four of the pigs and the sickness of the others before the end of the 
time. 
Whether the fat-soluble vitamines pass into the crude oil to any 
extent is not known. McCollum (5, 6 ) has shown that ether extraction 
of many seeds does not remove it, possibly as it is a combination not
