6. The same phenomena occur hi man. 



6. The grave abatement of temperature produced by a pain 

 lasting ten minutes would appear to be dependent upon an al- 

 teration of the chemical actions of the bod}^, and not merely to 

 an indirect influence exerted upon the vaso-motor nerves. 



In order to clearly determine the truth concerning the influ- 

 ence of irritation upon a sensitive nerve I have myself per- 

 formed the following experiments, which are, of course, repe- 

 titions of those of earlier observers. The records of these 

 experiments are as follows: —

 thermometer placed in peritoneal cavit}-.
