by Lindsey (6, 7) in the digestion experiments hereafter referred to, and 

 with Henry and Morrison's average of the composition of 778 samples 

 (5, p. 633), is contained in Table I, from which it appears that our hominy 

 feed was of normal composition.

The composition of the maize meal employed in this experiment 

 (designated as experiment 211) and of that used in other experiments 

 here, and likewise Henry and Morrison's average of 5,335 analyses 

 (5, p. 633), is shown in Table H.
