In the case of No. 5, which lost no less than I'lOO kilos, in seventy- 

 three days, this loss of weight principally occurred during the last 

 seven days, for up to that period this monkey had only lost 300 

 grammes. During the last seven days, however, severe diarrhoea set 

 in, followed by rapid wasting. The same holds good as regards the 

 other cases. So that although the monkeys on this diet lost weight, 

 possibly from the food not being sufficiently nutritious, the principal 

 loss of weight was apparently due to the diarrhoea. 



When we come to consider the diarrhoea, we see that all six monkeys 

 developed this condition sooner or later. As a rule it commenced by 

 being very intermittent, and becoming more severe towards the end, 

 when it speedily proved fatal by the general loss of strength, &c., 

 which it occasioned. 



The diarrhoea in monkey No. 1 did not commence until it had been 

 sixty-two days on the diet, when it proved fatal after seven days. In 

 the case of monkey No. 5, on the other hand, it began after thirteen 

 days, but was only slight, and at intervals of three or four days, 

 after which it became very severe ; during the last seven days there 

 was rapid wasting, and death occurred on the seventy-third day. 



In the case of monkey No. 3, the diarrhoea commenced, however, on 

 the third day, when it was very severe, and afterwards, although the 

 diarrhoea was not so acute and occurred only at intervals, the animal 

 became very feeble, and on the twenty-eighth day was killed by 

 chloroform. At the autopsy no cause for the feeble condition could be
