ADDITIONAL NOTES. 



NOTE A. (Page 36.) 



IN the experiments related in my two memoirs 

 on the production of animal heat, it has been 

 seen that the animals in which the circulation of 

 the blood was maintained by means of artificial 

 respiration after the removal of the brain, or the 

 destruction of its functions by the agency of a 

 narcotic poison, cooled more rapidly than those 

 in which the circulation had entirely ceased. 



The general result as to the loss of heat in 

 animals under these circumstances has been con- 

 firmed by the observations of other experimen- 

 talists, especially of Dr. Ghossat, M. Le Gallois, 

 and Dr. Wilson Philip. It is, however, stated 

 by M. Le Gallois, that in his experiments the 

 loss of heat was not uniform, and that while in 

 some instances it was greater in the animal 

 under the influence of artificial respiration than 

 in the dead animal, in other instances it was 

 the reverse, the latter having preserved a some- 

 what higher temperature than the former. 



I know that my observations were made with 

 great care, at the same time that they were con-
