ART. VI. 

 REVERTENTIA. 



I. THOSE THINGS, which reftore the natural order of the in- 

 verted irritative motions, are termed Revertemia. 



1. As muflc, caftor, afafoetida, valerian, eflcntial oils. 



2. Externally the vapour of burnt feathers, of volatile falts, 

 or oils, blifters, finapifms. 



Thefe reclaim the inverted motions without increafing the 

 heat of the body above its natural (late, if given in their proper 

 dofes, as in the globus hyftericus, and palpitation of the heart, 



The incitantia revert thefe morbid motions more certainly, as 

 opium and alcohol ; and reftore the natural heat more ; but if 

 they induce any degree of intoxication, they are fucceded by 

 debility, when their fiimulus ceafes. 



II. OBSERVATIONS ON THE REVERTENTIA. 



I. i. The hyfteric difeafe is attended with inverted motions 

 feebly exerted of the cefophagus, inteftinal canal and lymphat- 

 ics of the bladder. Hence the borborigmi, or rumbling of the 

 bowels, owing to their fluid contents defcending as the air be- 

 neath afcends. The globus hyftericus confifts in the retrograde 

 motion of the cefophagus, and the great flow of urine from that 

 of the lymphatics ipread on the neck of the bladder ; and a copi- 

 ous falivation fometimes happens to thefe patients from the in- 

 verfion of the lymphatics of the mouth ; and palpitation of the 

 heart owing to weak or incipient inverlion of its motions ; and 

 fyncope, when this occurs in its greateft degree. 



Thefe hyfteric affeclions are not neceflarily attended with 

 pain ; though it fometimes happens, that pains, which originate 

 from quiefcence, afflict theie patients, as the hemicrania, which 

 has erroneoufly been termed the clavus hyftericus ; but which is 

 owing folely to the inaction of the membranes of that part,like 

 the pains attending the cold fits of intermittents, and which fre- 

 quently returns like them at very regular periods of time.
