470 THEORY OF FEVER. SUP. I. tf. 11. 



a great accumulation of the sensorial power of association occurs, 

 which is exerted on the pulmonary and cutaneous absorbents by 

 reverse sympathy, and produces a great absorption of the fluid 

 effused into the cellular membrane in anasarca, with dry skin; 

 constituting one kind of atrophy. 



But if at the same time the secerning vessels of the stomach 

 are stimulated into so violent activity as to induce great conse- 

 quent torpor, as probably happens when contagious matter is 

 swallowed into the stomach with our saliva, those of the heart 

 and arteries act feebly from the deficient excitement of the power 

 of association; and then the cutaneous and pulmonary secerning 

 vessels act with greater force than natural, owing to the accu- 

 mulation of the sensorial power of association; and unnatural 

 heat of the skin, and of the breath succeed; but without fre- 

 quency of pulse, constituting the paresis irritativa of Class I. 2. 

 1 . 2. And lastly, if a paucity of blood attends this paresis, or 

 some other cause inducing a frequency of pulse, the febris inirri- 

 tativa, or fever with weak pulse, is produced. 



But on the contrary, when the stomach has previously been 

 rendered torpid by defect of stimulus, as by hunger, if food be 

 too hastily supplied, not only great exertion of the stomach it- 

 self succeeds, but fever with strong pulse is induced in conse- 

 quence; that is, the heart and arteries are excited into more ener- 

 getic action by the excess of the power of association, which 

 catenates their motions with those of the stomach. For the re- 

 dundancy of sensorial power of irritation, which was accumu- 

 lated during the inactivity of the stomach, and is now called into 

 action by stimulus, actuates that organ with increased energy, 

 and excites by these increased motions the sensorial power of 

 association; which has also been accumulated during the inacti- 

 vity of the heart and arteries; and thus these organs also are 

 flow excited into greater action. 



So after the skin has been exposed some hours to greater heat 

 than natural in the warm room, other parts, as the membranes 

 of the nostrils, or of the lungs, or of the stomach, are liable to 

 become torpid from direct sympathy with it, when we come in- 

 to air of a moderate temperature; whence catarrhs, coughs, and 

 fevers. But if this torpor be occasioned by defect of stimulus, 

 as after being exposed to frosty air, the accumulation of sen- 

 sorial power is exerted, and a glow of the skin follows, with 

 increased digestion, full respiration, and more vigorous circula- 

 tion. 



11. It may be asked, Why is there a great and constant accu- 

 mulation of the sensorial power of association, owing to the tor- 

 por of the stomach and heart and arteries, in continued fever
