DIGESTIBILITY OF SOME VEGETABLE FATS. 3 
Arnschink * reports an experiment of four days' duration with a 
dog of 8 kilograms body weight. Fifty grams of olive oil was consumed 
daily and 97.77 per cent digested. 
Olive oil has been studied from another viewpoint, namely, its 
ability, as compared with certain animal fats such as butter and 
cod liver oil, to maintain growth. Work along these lines has been 
reported by Osborne and Mendel 2 and McCollum and Davis, 3 who 
concluded that olive oil was not capable of stimulating or maintain- 
ing growth. 
In experiments here reported five subjects took part in the 11 diges- 
tion experiments, the results of which are given in the following 
tables :
