DIGESTIBILITY OF SOME VEGETABLE FATS. 
manufactured in its laboratories, and being freshly made was judged 
to be of most excellent quality. The commercial samples were much 
older, but were considered excellent in odor, flavor, and color. There 
was no apparent difference in the flavor of the two samples, which 
would seem to indicate that peanut oil which has been carefully han- 
dled has good keeping qualities, and as no noteworthy differences in 
properties appeared in the digestion experiments no further reference 
will be made to the source of the oil used. 
Four different subjects assisted in the study of this fat, and the 
usual uniform and standardized conditions of conducting the work 
were maintained throughout the experiments. The results of the 
five tests are as follows:
