comparison with similar data obtained with this subject during more or less 

 prolonged periods of inanition. In many instances the phosphorus was deter- 

 mined both by titration with uranium acetate and by the method of fusion 

 with sodium peroxide, and both sets of figures are given for comparison. 

 The other determinations are presented in the same manner as for the fasting 

 experiments.

It has been assumed that the feces for a given day result from the food of the previous 

 day ; the feces from which the energy here given was calculated were excreted on the day 

 following the one to which they are here assigned. Compare table 170, p. 293.
