 feeble as not to move. They all diexi except 

 the first and in the following succession. The 

 last animal removed from the cold died in less 

 than two hours ; the animal removed the 

 third lived near three hours : the minimal re-

 hours. The animal removed 'the first, after 

 one hour was so feeble as to be incapable of 

 motion ; after five hours, he had recovered in 

 some degree, and was then put into cold water; 

 the day following he was weak, biit* at length 

 entirely recovered.

Ten drops were thrown into the stomach of 

 a frog of equal size as the other four, he was 

 made weak by it for several hours, but after 12 

 hours had elapsed had nearly recovered all his 

 former strength. 



From these experiments, I conclude that the 

 capacity of receiving the action of stimuli, is 

 encreased by the effect produced from the ap- 

 plication of the sedative cold. 



The particularization of the effects of this 

 sedative power furnishes us with the following 

 conclusions.
