From the one hundred and ninetieth to the one hundred and ninety- 

 fifth day of tlie experiment, number VI no longer exhibited such live- 

 liness and muscular strength, but appeared to be lazy and weak. There- 

 fore, on the two hundredth day, it seemed necessary to increase the 

 amount of his food. At first, 3 50 calories were given, but the animal 

 was apparently already too weak to recover, for it died on the morning 

 of the two hundred and third day, doubtless of general weakness. No 

 sign of disease was shown at autopsy except extreme emaciation, an 

 absolute lack of subcutaneous fat, general ansemia of all the organs, 

 and an unusually soft consistency of the muscles. 



Number V was killed as a control animal a few days later by bleeding. 

 The animal showed a well-developed layer of subcutaneous and visceral 

 fat and norm'al internal organs. 



The analyses gave the following results.
