The subjects ate on an average per man per day 73.8 grams of the 
fat melting at 43° C, 79.7 grams of the fat melting at 43.2° C, and 
90.3 grams of the fat melting at 51.1° C. The maximum amount of 
blended peanut fat eaten per man per day was 78.4 grams of the 43° (X 
fat, 100.1 grams of the 43.2° C. fat, and 109.6 grams of the 51.1° C. 
fat. 
The average coefficients of digestibility were 96.6 per cent for the 
43° C. fat, 97.4 per cent for the 43.2° C. fat, and 92.8 per cent for tha 
51.1° C. fat. The subjects remained in apparently normal health and 
suffered no physiological disturbances. 
Discussion. — A summary of the results obtained from these experi- 
ments with blended fats of different melting points prepared out of 
corn, cottonseed, and peanut oil is given in Table 10.
