Class I. 3 . i . i o. OF IRRITATION. 1 3 7 



phatic diabetes, are the mod common fymptoms of the hyfteric 

 diferfe; to which fametimes is added the lymphatic falivation, 

 and fits of fvncope, or convulfion, with palpitation of the heart 

 (which probably confifts of retrograde motions of it.;, and a great 

 fear of dying, Which lad circumftance diftinguimes thefe con- 

 vulfions from the epileptic ones with greater certainty than any- 

 other fingle fymptom. The pale copious urine, cold (kin, palpi- 

 tation, and trembling, are the fymptoms excited by great fear. 

 Hence in hyfteric difeafes, when thefe fymptoms occur, the fear, 

 which has been ufually ailbciated with them, recurs at the fame 

 time, as in hypochondriafis, Clafs I. 2. 4. 10. See SecX XVI.

The convulfions which fometimes attend the hyfteric dlfeafe, 

 are exertions to relieve pain, either of feme torpid, or of fome 

 retrograde organ 5 and in this refpecT they refemble epileptic 

 convulfions, except that they are feldom fo violent as entirely to 

 produce inienfibility to external ftimuli ; for thefe weaker pains 

 ceafe before the total exhauftion of fenforial power is produced, 

 and the patient fmks into imperfect fyncope ; whereas the true 

 epilepfy generally terminates in temporary apoplexy, with per- 

 feci infeniibility to external objects. Thefe convulfions are lefs 

 to be dreaded than the epileptic ones, as they do not originate 

 from fo permanent a caufe. 



The great difcharge of pale urine in this difeafe is owing to 

 the inverted motions of the lymphatics, which arife about the 

 neck of the bladder, as defcribed in Seel. XXIX. 4. 5. And 

 the lymphatic falivation arifes from the inverted motions of the 

 falivary lymphatics. 



Hyfteria is diftinguifhed from hypochondriafis, as in the Matter 

 there are no retrograde motions of the alimentary canal, but lim- 

 ply a debility or inirritabiiity of it, with distention and flatulency. 

 It is diftinguifhed from apepfia and cardiaigia by there being noth- 

 ing ejec~led from the ftomach by the retrograde motions of it, 

 or of the cefophagus.

 apifms externally ; to which mult be added a clyfter of cold wa- 

 ter, or iced water ; which, according to Monf. Pornme, relieves 

 thefe hyfteric fymptoms inftantaneoully like a charm ; which it 

 may efFeclby checking the inverted^motio.ns of the inteftinal ca- 

 nal by the torpor occasioned by cold *, or one end of the intefti- 

 nal canal may become flrengthened, and regain its peri. Baltic 

 motion by reverfe fympathy, when the other end is rendered 

 torpid by ice- water. (Pom me des ArTcclions Vaporeufes, p. 25.) 

 Thefe remove the prefent fymptoms ; and bark, fteel, exercife,
