fuch as prevent the too great diminution of fenforial power in 

 the hot fit, and the too great accumulation of it in the cold one. 



2. Where the exertion of the fenforial powers is much in- 

 creafed, as in the hot fits of fever or inflammation, the follow- 

 ing are the ufual means of relieving it. Decreafe the irritations 

 by blood-letting, and other evacuations ; by cold water taken 

 into the ftomach, or injected as an enema, or ufed externally ; 

 by cold air breathed into the lungs, and diffufed over the fk-n ; 

 with food of lefs ftimulus than the patient has been accuilom- 

 ed to. 



3. As a cold fit, or paroxyfrn of inaclivity of fome parts of 

 the fyftem, generally precedes the hot fit, or paroxyfm of exer- 

 tion, by which the fenforial power becomes accumulated* this 

 cold paroxyfm fliould be prevented by ilimulant medicines and 

 diet, as wine, opium, bark, warmth, cheerfulnefs, anger, furprife. 



4. Excite into greater action fome other part of the fyftem, by 

 which means the fpirit of animation may be in part expended, 

 and thence the inordinate actions of the difeafed part may be 

 leflened. Hence when a part of the fkin acts violently, as of 

 the face in the eruption of the fmall-pox if the feet be cold they 

 {hould be covered. Hence the ufe of a blifter 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 exhauft the fpirit of ani- 

 mation, and then decreafe the ftimulation beneath its natural 

 quantity. Hence after fudorific medicines and warm air, the 

 application of refrigerents may have greater effect, if they could 

 be adminiftered without danger of producing 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. 



VIL Cure of decreafed Exertion. 



I. WHERE the exertion of the fenforial powers is much de- 

 creafed, as in the cold fits of fever, a gradual accumulation of 

 the fpirit of animation takes place , as occurs in all cafes where 

 inaclivity or torpor of a part of the fyftem exifts ; this accumu- 

 lation of fenforial power increafes, till ftimuli lefs than natural 

 are fufficient to throw it into action, then the cold fit ceales ; 

 and from the action of the natural ftimuli a hot one fucceeds 

 with increafcd activity of the whole fyftem.
