GROWTH OF ORGANS AS AFFECTED BY THE FEEDING OF SUDAN III 



In order to determine the effect of Sudan III on the growth of 

 the organs, young rats just weaned were treated in the following 

 manner. One or two rats were measured and the weights of the 

 organs determined at the beginning of the experiment. The re- 

 maining rats were examined at different intervals in order to 

 compare the organ weights at later ages with those at the begin- 

 ning of the experiment. At the end of the experiment the rats 

 which had been kept as controls and which were receiving the 

 normal ration were examined together with the last test rats. 



The object of this final procedure was to show the amount of 

 growth the organs should have made had the rats not been sub- 

 jected to the Sudan III diet. The last test group was also util- 

 ized to determine the percentage of water and the lipoids in the 

 organs. The results of these examinations are given in table 2 

 for the younger, and table 3 for the older series.
