DISCUSSION 
From the tables here presented it will be found that calculations 
were made by subtracting the weekly weight of each animal from the 
Fig. i.—N o. 41 and 43 belong to Group I, which were fed the basal balanced ration. No. 45 and 46 belong 
to Group II and received 50 parts of ground pumpkin seeds for every 50 parts of the basal balanced ration. 
No. 40 and 42 constitute Group III, which were fed ground pumpkin seeds only. The curves represent 
the growth in body weight of the rats beginning June 1 and ending August 10. The broken lines pas* 
through the points at which the feeding trial of pumpkin seeds started. 
preceding weekly weight of the same animal. The total gain consti¬ 
tuted the algebraic sum of the differences of all the animals in each 
group. The total gain per 100 gm. body weight was obtained by divid-
