The results of a series of tests in which three diets composed essentially of wheat were fed to human subjects indicated that the ground wheat muffins diet and shredded wheat diet tested were probably of the same digestible energy value. These two diets were combined to form one basal diet which was fed with supplements of raw and cooked egg at three levels in a second series of tests to humans and in a third series to rats. Higher digestion values were obtained for cooked egg than for raw egg with both species. Rats digested all fractions of the basal diet but ether extract to a lesser extent than did humans. Physiological fuel values calculated from the data were compared with those of Atwater. The applicability of the latter to individual foods and to different species was questioned. Some refinements of experimental technique were suggested.
