ORDO III. 



Retrograde Associate Motions. 



GENUS I. 

 Catenated with Irritative Motions. 



THOSE retrograde associate motions, the first links of which 

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

 the retrograde moiions are consequent to debility, or inactivity, 

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

 creased actions, both in this and the former classes. 



SPECIES. 



1. Diabetes irritata. When the absorbents of the intestines 

 are stimulated too strongly by spirit of wine, as in the beginning 

 of drunkenness, the urinary absorbents invert their motions. 

 The same happens from worms in the intestines. In oilier 

 kinds of diabetes may not the remote cause be the too strong 

 action of ihe cutaneous absorbents, or of the pulmonary ones? 

 May not in such cases oil externally or internally be of service? 

 or warm bathing for an hour at a time? In hysteric inversions 

 of motion, is some other part too much stimulated? or pained 

 from the want of stimulus? 



2. Sudor frigidus in asthmate. The cause of the paroxysms 

 of humoral asthma is not well understood; 1 suppose it to be ow- 

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

 pulmonary vessels, as happens probably to other viscera at the 

 commencement of intermittent fevers, and to a consequent accu- 

 mulation of fluids in them; which at length, producing great irri- 

 tation or uneasy sensation, causes the violent efforts to produce 

 the absorption of it. The motions of the cutaneous absorbent 

 vessels by their association with those of the pulmonary ones be- 

 come retrograde, and effuse upon the skin a fluid, which is said 

 to be viscid, and which adheres in drops. 



A few days ago I saw a young man of delicate constitution, in 

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

 before had a peripneumony, and had been ever since subject to 

 difficult respiration on exertion, with occasional palpitation of 

 his heart. He was now seized about eight at night after some 

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

 culty of breathing.' He gradually became worse, and in about
