BULLETIN 507, TJ. S. DEPARTMENT OF AGRICULTURE. 
A series of experiments, accordingly, has been made to determine the 
digestibility of cream in comparison with that of other fats. 
Cream of average quality was purchased of a local dealer and 
incorporated in a blancmange in the manner previously described, 
except that, owing to the larger volume of the cream, no skim milk 
was necessary and a much smaller amount of cornstarch was needed 
to thicken the mixture. The results of seven digestion experiments, 
in which Hive different subjects participated, follow: 
Data of digestion experiments with cream in a simple mixed diet.
