Sixty per cent of velvet beans used to supply the water-soluble vitamin 

 allowed only a very small amount of growth (fig. 14).

Fig. II. — Gain in weight of lot 70 on ration of velvet beans, 30 per cent; No. 32 salts, 4 per cent; casein, 

 12 per cent; and dextrin, 64 per cent. The dextrin carried alcoholic extract of 10 gm. ether-extracted wheat 

 embryo. Y indicates point at which young were littered. 



In order to determine whether the water-soluble vitamin was destroyed 

 during the process of autoclaving, 40 per cent velvet beans was fed un- 

 cooked. Very little growth resulted, nor was there any improvement
