1st. llic sedative effect of cold diminishes 

 all the actipns of the body., 



2d. It diminishes the temperature by ex- 

 periment. 



3d. It diminishes the action of the heart and 

 arteries in the first instance, by rendering them 

 quick and feeble ; in the second by rendering 

 them slow and feeble. 



4th. That its effects are experienced more 

 reacjily by adult than young, animals. Exp. 

 a. b. c. Section 2d. The three last , cojiclu^ 

 sions proven by thenrt. . 



5th. That animals of an inferior temperature, 

 whose excitability is abundant, can subsist 

 under lower degrees of this power, than warm- 

 blooded animals, or those whose excitability is 

 not so abundant. Exp. 47, 48, 49. 



6th. That animals exposed to its effects have 

 their capacity to receive the action of stimu- 

 lants encreased. Exp. r50* 



From these conclusions, it appears proper to 

 express a sedative in the following manner. 



A poiver which diminishes the action of the 

 heart and arteries y the energy of the brairiy. 

 and encreases the excitability of the system. 



By comparing these conclusions with those 

 drawn at page 62, it will be found that the 

 ^ff(^cts produced by stimulant powers and by 

 tbej^edativ.e one of cold, are d^Tjtctly the rqyerse
