DIGESTION EXPERIMENTS WITH SOFTER KAFIR BREAD. 
In the second series of tests with dwarf kafir a gingerbread made 
by the recipe on page 5 was eaten with a basal ration containing 
potatoes, apple sauce, butter, and sugar. Since the ration contained 
no milk, it supplied considerably less protein than was furnished in 
the preceding experiments; and the diet proved so satisfactory that 
bread was made in the same way for use in the tests with the other 
sorghums and in the experiments with corn and wheat meals which 
were made for the purpose of comparison. The data of the experi- 
ments with kafir bread are reported in the following tables:
