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:
