The food eaten per man per day provided on an average 16 grams 
of protein, 47 grams of fat, and 310 grams of carbohydrate, and its 
fuel value averaged 1,740 calories. The maximum amount of cod- 
liver oil consumed by any subject was 53 grams per clay. The co- 
efficient of digestibility was high in every case, and the average fig- 
ure, 97.7 per cent, indicates a very complete utilization. Except that 
all the subjects were somewhat constipated, no physiological dis- 
turbance was noted. 
In thoroughness of digestion, cod-liver oil agrees closely with the 
majority of fats and oils that have a melting point at or below body 
temperature. 
JAVA-ALMOND OIL. 
The digestibility of this oil is of interest not only because the nut 
is valued highly in Java, but also because the finely ground kernels 
mixed with water to a kind of emulsion and added to milk find there 
a special use in infant feeding with, it is believed, good results. 
The Java almonds (Canarium commune) needed for this experi- 
ment were obtained from Java by the Office of Foreign Seed and 
Plant Introduction, Bureau of Plant Industry. The nut resembles 
somewhat a small-sized pecan in shape, and the kernels are much 
like a small almond in appearance and have a very agreeable flavor. 
In the present work a small-sized laboratory oil press was used 
to express the oil, which was of clear yellow color and bland in flavor. 
The supply available was sufficient for only two tests. The results 
are summarized in Table 2.
