DIGESTION EXPERIMENTS WITH FETERITA BREAD. 
Feterita was also used in the form of a bread flavored with ginger, 
experience having shown that all such gingerbreads, owing to their 
slightly sweet and spicy flavor, are very appetizing. For example, 
the subjects ate an average of eight-tenths of a pound of the feterita 
bread per day and over a pound of the kafir bread which was made 
according to the same recipe. The data of the digestion experiments 
with feterita bread eaten with a simple mixed diet follow:
