Number V, of smaller weight in tlie beginning, was selected to be so 

 fed as to permit a normal growth; number VI, the heavier animal, was 

 to be kept at a constant weight. 



Onl)'- one accident occurred during the entire course of the experiment. 

 (Table 15.) Prom the fourteenth to eighteenth day, number V suffered 

 from overfeeding. By a slight restriction of food for two days, the 

 trouble was remedied, but no increase in weight occurred from the 

 eleventh to twenty-first day.
