normally was caused by some toxic principle in the soybean, and in 

 order to throw more light on this point the following experiment was 

 planned. It was conducted in an airy, well-lighted basement room of 

 the Kentucky Agricultural Experiment Station. 



Two lots of chicks, designated "A" and "B," consisting of 12 and 11 

 White Leghorn chicks, respectively, were selected entirely at random 

 and fed rations composed of equal parts of soybeans, oats, wheat, ship 

 stuff, sunflower seed, and cracked corn, supplemented by sour skim milk, 

 sprouted oats, shredded cabbage, grit, and oyster shell. The food of lot 

 A was given to them in the usual manner of feeding. In the case of lot 

 B the grains were ground together, well mixed with a small quantity of 

 distilled water, and baked in an electric oven. The temperature of the 

 oven was kept at 420° F., and the mixture was frequently stirred. The 

 baked feed was ground and fed to lot B in the same way as was the 

 uncooked mixture to lot A. Table I gives the weights of the chicks, 

 their increase in weight, and the number surviving each week.
