EXPLANATION OF CHARTS 



The following charts show the identification numbers of the guinea pigs, 

 the rates of growth, and the number of weeks' duration of experimental 

 feeding. 



The numbers above the growth curves are the identification numbers of 

 the animals; the weights of the guinea pigs are shown by the figures on 

 the axes of ordinates; the number of weeks of experimentation is indicated 

 by the numbers on the axes of abscissae. An arrowhead terminating the 

 growth curve indicates the death of the animal in question. If the arrow- 

 head is lacking, the animal was still living at the end of the experiment.
