becaufe its ufual quantity of fenforial power is previoufly ex- 

 haufted by the great ftimulus of the foxglove ; and hence it 

 feems probable, that the great accumulation of fenforial power, 

 which now caufes the increafed action of the abforbents, is pro- 

 duced in confequence of the inactivity of the heart and arteries ; 

 which inactivity is induced by deficient excitement of the fen- 

 forial power of afTociation between thofe organs and the ftom- 

 ach, and not by any previous exhauttion of their natural quan- 

 tity of fenforial power ; whereas in ileus, where the torpor of 

 the ftomach, and confequent ficknefs, is induced by reverfe 

 fympathy with an inflamed intettine, that is, by diflevered or 

 defective afTociation ; the accumulation of fenforial power, 

 which in that difeafe lo violently actuates the cellular, pulmo- 

 nary, and cutaneous abforbents, is apparently produced by the 

 torpor of the ftomach and lacteals, and the confequent accumu- 

 lation of the fenforial power of afTociation in them owing to 

 their lefiened action in ficknefs. 



4. This accounts for the dry fkin in fevers with weak pulfe, 

 where the ftomach and the heart and arteries are in a torpid 

 itate, and for the fudden emaciation of the body ; becaufe the 

 actions of the cellular and cutaneous abforbents are increafed 

 by reverfe fympathy with thofe of the ftomach, or with thole of 

 the heart and arteries -, that is by the expenditure of that fenfo- 

 rial power of afTociation, which is accumulated in confequence 

 of the torpor of the ftomach and heart and arteries, or of either 

 of them ; this alfo explains the fudden abforption of the milk in 

 puerperal fevers ; and contributes along with the heat of the 

 refpired air to the drynefs of the mucous membrane of the 

 tongue and noitvils. 



5. Befides the reverfe fympathy, with which the abforbent 

 vefTels of the ftomach and upper inteftines act in refpect to all 

 the other abforbent vefTels, as in the exhibition of digitalis, and 

 in ileus ; there is another reverfe fympathy exilts between the 

 capillaries, or fecretory vefTels of the ftomach, and thofe of the 

 fkin. Which may neverthelefs be occafioned by the accumula- 

 tion of fenforial power by the torpor of the heart and arteries, 

 which is induced by direct fympathy with the ftomach ; thus 

 when the torpor of the ftomach remains in a fever-fit, which 

 might otherwife have intermitted, the torpor of the heart and 

 arteries remains t alfo by direct: fympathy, and the increafed cu- 

 taneous capillary action, and confequent heat, are produced by 

 reverfe fympathy ; and the fever is thus rendered continual, 

 owins primarily to the tcroor of the ftomach. 



6. The reverfe fympathy, which exifts between tue capilla- 

 ries of the ftomach and the cutaneous capillaries, appears by the 



chill nefs
