EFFECTS ON DEPRIVATION OF FOOD

These figures are in practical agreement with those of later experimenters. 

 They show that the chief losses are sustained by the adipose tissue, the 

 muscles and glands. The nervous structures and the heart are maintained 

 at the expense of the other tissues and show but little change. 



The effect of starvation on the temperature of the various animals ex- 

 perimented on by Chossat was very distinct. For some time the variation 

 in the daily temperature was more marked than its absolute and continuous 

 diminution, the daily fluctuation amounting to 3 C. instead of 0.5 to i C.,

as in health. The temperature fell very rapidly a short time before death, 

 and death ensued when the loss had amounted to about 16 . 2 C. It has been 

 often said, and with truth, that death by starvation is really death from want 

 of heat. The effect of the application of external warmth to animals cold 

 and dying from starvation is more effectual in reviving them than the ad- 

 ministration of food. 



The symptoms produced by starvation in the human subject are hunger, 

 accompanied, or it may be replaced, by pain, referred to the region of the 

 stomach; insatiable thirst; sleeplessness; general weakness, and emaciation. 

 The exhalations both from the lungs and from the skin are fetid, indicating
