Fisher — The Effect of Diet on Endurance. 13 



" The odor was very slight in almost every specimen in the last 

 series, a marked difference between these and series I and II, 

 particularly I. The average weight is less than in both series I and 



II (av. wt. of series 1= 137.3 grams; of II — 164.8 grams, and 



III = 120,4 grams). 



" The figures indicate considerable difference in the putrefactive and 

 fermentative properties of the three series, and the decrease is progres- 

 sive. In series I the amount of proteid dissolved was much larger 

 than in II and III. . . The specimens [of series III] were more 

 solid generally than in both previous series. I was unable to note 

 any api^reciable difference in the microscopic appearance of the last 

 series as compared with the previous, except that in specimen B of 

 the last series a large number of moulds were present. This has little 

 significance, however." 



TABLE VIII. FECAL TESTS' 

 Putrefactive Deuree Fermentative Property 



We here observe that the degree of putrefaction in the last two 

 tests was usually considei'ably less than its magnitude in the first 

 test. The least change in the feces occurred in the cases of Lq., M, 

 and E., and the greatest changes in P., T. and W. Here again we 

 find some correspondence between the assiduity of the men and the 

 observed physiological changes ; for E. and M. were the least and P. 

 and W. the most careful among the experimenters. 



A critic has raised the question whether the improvement in the 

 feces indicates lessened absorption of poisons, and whether, if the 

 feces were longer retained, the improvement in their character might 

 not be in consequence of the abstraction from them and absorption
