which follows galvanization of a sensory nerve is the result of 

 a reflex excitement of the inhibitory chemical nerves. 



If the experimental results be found to agree with this 

 reasoning, the asserted correctness of the premises is greatly 

 corroborated. The following experiments were instituted to 

 test the matter. 



Experiment 9. 



A stout young dog. Medulla nearly cut through at its 

 junction with the pons. 



Time. Temp. Remark. 



1 lOljo Galvanization of a sensitive nerve with an intense cur- 

 rent for half a minute had no perceptible effect ou 

 temperature. Dog watched many minutes. 



Experiment 10. 



A stout terrier. Medulla oblongata very nearly severed from 

 pons. 



Time. Temp. 



2.10 10T|° A very intense current passed for one minute throu<rh 

 the axillary nerves had no influence on the tempera- 

 ture. Animal watched many minutes. 



Experiment 11. 

 A powerful dog. Medulla oblongata separated from pons. 



Time. Temp. Remarks. 



1.30 105j° Galvanization of a large sensitive nerve with a very 

 strong Faradaic current for one and a half minutes 

 had no perceptible effect on the temperature. Ani- 

 mal watched many minutes. 



The results of these experiments certainly are in accord with 

 and corroborate the a priori reasons. As a contrast to them, 

 may be profitably studied some which I have made on animals 

 suffering witli pyaemic fever. The temperature was not very 

 high, but it was the highest that I have seen developed in a
