The subjects ate on an average per man per day 62.3 grams of the 
fat melting at 41.3° C, 52.6 grams of the fat melting at 45.8° C, 76.3 
grams of the fat melting at 47.8° C, 49.4 grams of the fat melting at 
48.1° C, and 56.9 grams of the fat melting at 50° C. The maximum 
eaten per day was 63.3 grams of the 41.3° C. fat, 52.8 grams of the 
45.8° C. fat, 98.1 grams of the 47.8° C. fat, 53.3 grams of the 48.1° 
C. fat, and 62.7 grams of the 50° C. fat. The average coefficients 
of digestibility found were 96.6 per cent for the 41.3° C. fat, 96.4 
per cent for the 45.8° C. fat, 94.2 per cent for the 47.8° C. fat, 94.4 
per cent for the 48.1° C. fat, and 87 per cent for the 50° C. fat. 
The subjects remained in normal health except for the experiments 
with fat melting at 50° C. In the reports of their condition in this 
case the subjects mentioned a feeling of nausea and headache. Such 
conditions were not noted in the other experiments with hydrogenated 
fats of high melting point and may not be directly ascribable to 
the fat ingested. Similar effects had been noted in earlier experi- 
ments in which cocoa fat 21 and cupuassu fat 22 were eaten in large 
quantities. 
Blended peanut fats. — Thirteen experiments were conducted with 
blended peanut fat, five with fat melting at 43° C. and four each with 
fats melting at 43.2° C. and 51.1° C. The results are summarized in 
Table 9.

tbe seed of the fruit of the cupuassu tree {Thcobroma grandifiora Schum).
