European countries, however, this oil is quite extensively used and is 
an important constitutent of the dietary. According to Lewko- 
witsch 1 the sunflower is largely grown in southern Russia and the 
cold-pressed oil is used there for culinary purposes and for margarin 
manufacture. 
As the production of sunflower seed in this country may be ma- 
terially increased, and since no tests of the digestibility of this oil 
were found on record, the experiments here reported were made to 
determine the digestibility of sunflower-seed oil when eaten as a con- 
stituent of a uniform diet such as was served during the test periods 
with the edible fats previously studied. 
The data of the digestion experiments with sunflower-seed oil are 
included in the following tables :
