fed in doses of 2 cc., 4 cc., 6 cc., 8 cc., 10 cc., 12 cc., 15 cc., per 

 rat per day. These amounts were fed without regard to the 

 weight of the rat and the same amount was fed throughout 

 the experimental period. The data are summarized in Tables 

 V and VI and Chart I, Figures I and II. 



TABLE V. 

 Diet 94 and unheated milk. 



K. = killed. D. = dead. 



* Since all rats did not live till the end of the experimental period, 

 averages could not be given for the last three weeks. 



(1) 4 rats D. at 64, 65, 77, 77 days. 

 2 rats K. at end of 12th wk. 



(2) 4 rats D. at 63, 66, 70, 74 days. 

 2 rats K. at end of 12th wk. 



TABLE VI. 

 Diet 107 and unheated milk. 



(1) 37 gms.=average weight at death. 

 56 days=average age at death. 



It will be noted that in both experiments (Tables V and VI) 

 the largest difference in weight gained for the same difference 

 in milk fed conies between 6 cc. and 8 cc. In order to prove
