Group 2 (table 2) consists of ten rats in various stages of inani- 

 tion. As is seen from the table these rats had been without food 

 for forty-eight to ninety-six hours and had lost from twelve to 

 twenty-four per cent in body weight. The three members of the 

 group which had lost as much as twenty per cent in weight 

 showed, upon section, little or no subcutaneous fat and but slight 

 traces in the omentum. Several of these animals are to be re- 

 garded as in the last stages of inanition. Of the ten members 

 of the group five have a very small quantity of fat in the cardiac 

 fibers, as in figure 1, four have a small amount, as in figure 2, 

 and one a moderate amount. Figure 1 from rat no. 23 (loss of 

 weight twenty per cent) shows a very small amount of fat and 

 this figure may be taken as characteristic of the inanition group. 



The animals of group 3 (table 3) were fed fats in the form of 

 butter, olive oil, pork fat and egg yolk. In order to increase the 

 quantity of fat consumed no food was given for twenty-four hours 

 preceding the initial feeding. When fats were to be given for 

 several days, feeding was not preceded by a fast. A little grain
