44 OF STIMULUS Sect. XII. i. 2. 



diminifhes the quantity of ' fenforial power in general. 2. In par- 

 ticular organs. 3. Induces the organ into fpafmodic ablions. 4. 

 Induces the antagonifi fibres into action. 5. Induces the organ in- 

 to convulfive or fixed fpafms. 6. Produces paralyfis of the or- 

 gan. V. Of fiimulus lefs than natural. 1. Stimulus lefs than 

 natural occafions accumulation of fenforial power in general. 2. 

 In particular organs ,fiufinng of the face in a frofiy morning. In 

 fibres fubjecl to perpetual fiimulus only, ^lantity of fenforial 

 power inverfely as the fiimulus. 3. Induces pain. As of cold, 

 hunger, head-ach. 4. Induces more feeble- and frequent contrac- 

 tion. As in low fevers. Which are frequently owing to deficien- 

 cy of fenforial power rather than to deficiency of fiimulus. 5. In- 

 verts fuccefifive trains of motion. Inverts ideas. 6. Induces pa- 

 ralyfis and death. VI. Cure of increafed exertion. 1. Nat- 

 ural cure of exhaufiion of fenforial power. 2. Decreafe the irri- 

 tations. Venefeciion. Cold. Abfiinence. 3. Prevent the pre- 

 vious cold fit. Opium. Bark. Warmth. Anger. Surprife. 

 4. Excite fame other part of the fyfiem. Opium and warm bath 

 relieve pains both from defect and from excefs of fiimulus. 5. 

 s?irfi increafe the fiimulus above, and then decreafe it beneath the 

 natural quantity. VII. Cure of decreafed exertion. 1. Nat- 

 ural cure by accumulation of fenforial power. Ague-fits. Synco- 

 pe. 2- Increafe the fiimulation, by wine, opium, given fo as not to 

 intoxicate. Cheerful ideas. 3. Change the kinds of fiimulus, 

 4. Stimulate the affociated organs. Blifiers ofufe in heart-burn, 

 and cold extremities. 5. Decreafe the fiimulation for a time, cold 

 bath. 6. Decreafe the fiimulation below natural, and then in- 

 creafe it above natural. Bark after emetics. Opium after vene- 

 feclion. Practice of Sydenham in chlorofis. 7. Prevent unnecef- 

 fary expenditure of fenforial power. Decumbent pofiure,filence, 

 darknefs. Pulfe quickened by rifing out of bed. 8. To the great- 

 efi degree of quiefcence apply the leaf} fiimulus. Other wife pa- 

 ralyfis or inflammation of the organ enfues. Gin, wine, blifiers, 

 defiroy by too great fiimulation in fevers with debility. Intoxica- 

 tion in the fiightefl degree fucceeded by debility. Golden rule for 

 determining the befi degree of fiimulus in low fevers. Another 

 golden rule for ditermming the quantity of fpirit which thofe, who 

 are debilitated by drinking it, ?nayfafely omit. VIII. Conclufion, 

 S^mefiimuli increafe the production cf fenforial power, 



I. Of fibrous contraction. 



1. If two particles of iron lie near each other without mo- 

 tion, and afterwards approach each other ; it is reasonable to 

 conclude that ft>;nething befides tiic iron particles is the caufeof 



their
