Further Experiments and Observations on the influence of the 

 Brain on the generation of Animal Heat. By B. C Brodie, 

 F. R. S. 



IN the Croonian Lecture for the year 1810*, I give an account Former ex- 

 of some experiments, which led me to conclude that the P enments - 

 production of animal heat is very much under the influence of 

 the nervous system. Some circumstances, which I have since 

 met with, illustrate this subject, and seem to confirm the truth 

 of my former conclusions.
