Retrograde AJjociate Motions* 



GENUS I. 



Catenated ivith Irritative Motions* 



Those retrograde aflbciate motions, the firft links of which 

 are catenated with irritative motions, belong to this genus. All 

 the retrograde motions are confequent to debility, or inactivity, 

 of the organ ; and therefore properly belong to the genera of de- 

 creafed actions both in this and the former clafles. 



SPECIES. 



i. Diabetes irritata. When the abforbents of the inteftineS 

 are ftimulated too ftrongly by fpirit of wine, as in the beginning 

 of drunkennefs, the urinary abforbents invert their motions. 

 The fame happens from worms in the inteftines. In other 

 kinds of diabetes may not the remote caufe be the too ftrong 

 action of the cutaneous abforbents, or of the pulmonary ones ? 

 May not in filch cafes oil externally or internally be of fervice ? 

 or warm bathing for an hour at a time ? In hyfleric inverfions 

 of motion is fome other part too much ftimulated ? or pained 

 from the want of flimulus ? 



2. Sudor frigidus in ajlhmate. The caufe of the paroxyfms of 

 humoral afthma is not well underftood ; I fuppofe it to be ow- 

 ing to a torpidity or inaction of the abforbents belonging to the 

 pulmonary veflels, as happens probably to other vifcera at the 

 commencement of intermittent fevers, and to a confequent ac- 

 cumulation of fluids in them ; which at length producing great 

 irritation or uneafy fenfation caufes the violent efforts to pro- 

 duce the abforption of it. The motions of the cutaneous ab- 

 forbent veflels by their aflbciation with thofe of the pulmonary 

 ones become retrograde, and effufe upon the fkin a fluid, which 

 is faid to be vifcid, and which adheres in drops. 



A few days ago I faw a young man of delicate conftitution in 

 what was called a fit of the afthma ; he had about two months 

 before had a peripneumony, and had been ever fince fubject to 

 difficult refpiration on exertion, with occafional palpitation of 

 his heart. He was now feized about eight at night after fome 

 exertion of mind in his bufinefs with cold extremities, and diffi- 

 culty of breathing. He gradually became worfe, and in about
