220 RISE OF TEMPERATURE 



it need scarcely be said, the organs concerned in 

 effecting oxidation have completely ceased to act. 



The development of animal heat probably occurs 

 at the moment when non-living matter becomes 

 living when the elements of compounds are sepa- 

 rated from one another to enter upon that state of 

 suspended affinity or equilibrium in which they seem 

 to be retained while the living state lasts. 



It is of the greatest importance in treating cases of 

 fever, to favour to the utmost the actions concerned in 

 carrying off heat during the persistence of the febrile 

 condition. Although direct cooling of the surface 

 will bring down the temperature of the body, it must 

 not be forgotten that the phenomena upon which the 

 development of heat depends cannot be influenced by 

 this proceeding. On the other hand, by keeping the 

 surface of the body warm and well covered by light 

 woollen things, the operation of the natural process 

 for lowering the temperature is favoured ; for when 

 the surface is kept warm, the arteries of the skin are 

 dilated and much blood is brought to the cutaneous 

 capillaries where free evaporation takes place, and 

 much fluid is in this way removed in the state of 

 vapour charged with heat. 



Mr. A. B. Garrod has shown that when the clothes 

 are removed from the body and the surface chilled, 

 the cutaneous arteries are caused to contract. The 

 blood is thus diverted from the surface of the body 

 to internal parts so quickly and so decidedly that its.
