Chart CVIII. Chart CIX. 



Chart CX. 



Chart CXI. 



Charts CVIII (rat 214, female), CIX (rat 219, male), CX (rat 220, 

 male), and CXI (rat 213, male) show the failure to induce more than 

 slight growth when gliadin forms the sole protein of the dietary, even under 

 conditions in which most other proteins have been found effective. That 

 the failure to grow is not due to insufficient food intake is evident. The 

 character of the diets is given in the table below.
