 ufe of a blilter applied near a topical inflammation. 

 Hence opium and warm bath relieve pains both 

 from excefs and defect of ftimulus. 



5. Firft increafe the general ftimulation above its 

 natural quantity, which may in fome degree ex- 

 hauft the fpirit of animation, and then decreafe the 

 ftimulation beneath its natural quantity. Hence 

 after iudorific medicines and warm air, the appli- 

 cation of refrigerants may have greater effect, if 

 they could be adminiftered without danger of pro- 

 ducing too great torpor of fome part of the fyftem ; 

 as frequently happens to people in health from 

 coming out of a warm room into the cold air, by 

 which a topical inflammation in confequence of 

 torpor of the mucous membrane of the noftril is 

 produced, and is termed a cold in the head.

 lefs than natural are fufficient to throw it into 

 action, then the cold fit ceafes ; and from the ac- 

 tion of the natural ftimuli a hot one fucceeds with 

 increafed activity of the whole fyftem. 



So in fainting fits, or fyncope, there is a tempo- 

 rary deficiency of fenforial exertion, and a confe- 

 quent quiefcence of a great part of the fyftem. This 

 quiefcence continues, till the fenforial power be- 

 comes again accumulated in the torpid organs; 

 and then the ufual diurnal ftimuli excite the revi- 

 vifcent parts again into action ; but as this kind 

 of quiefcence continues but a fhort time compared
