COMPOSITION OF THE FECES. 



The data for the discussion of the composition of the feces are taken 

 from several sets of tables. Table XXII, given herewith (p. 151), is a 

 summary showing by periods, for each individual, the average daily 

 weight of the wet feces, the percentage of water therein, and the weight 

 of the dry feces. Tables XLV-LV, prepared to show the nitrogen 

 balance in the body, give the total weight of nitrogen in the food, the 

 weight of nitrogen eliminated, and the percentage of nitrogen elimi- 

 nated. In the tables these facts are given in full for each individual, 

 and are also summarized by periods and series; but in the present dis- 

 cussion the percentages used are the averages for the various periods 

 only. Similar facts for phosphoric acid are to be found in Tables 

 LVI-LXVI; for fat in Tables LXVII-LXXV, and for calories in 

 Tables LXXVI-LXXXIV (see appendix).
