Scharlach R. The various items of the tables will be more fully- 

 explained in the discussion which follows. 



Group 1 (table 1) consists of fifteen adult rats fed for three 

 weeks with an abundance of raw grain, wheat bread and boiled 

 beef. The quantity of fat allowed was somewhat less than the 

 animals appeared to desire. This group of rats may be consid- 

 ered as having received food, fat, protein, and carbohydrate, 

 suitable for normal maintenance and growth. These rats were 

 kept in large well ventilated cages and when killed were all 

 in good nutritive condition. Of the fifteen rats in the group, 

 (table 1) ten have a moderate amount of fat in the cardiac fibers 

 as in figure 3 ; two have a large amount of fat in the fibers as in 

 figure 4, three have a small amount as in figure 2. Figure 3, 

 showing as it does a moderate amount of fat, may be taken as 

 representing the average condition of the group.
