5oo DISEASES OF VOLITION. SECT. XXXIV. j. 



cited by pleafurable fenfation, were exertions to re- 

 lieve pain. 



Tbe hunting fcene appeared to be rather an aft 

 of memory than of imagination, and was therefore 

 rather a voluntary exertion, though attended with 

 the pleafarable eagernefs, which was the confe- 

 quence of thofe ideas recalled by recollection, and 

 not the caufe of them. 



Thefe ideas thus voluntarily recolle&ed were fuc- 

 ceeded by fenfations of pleafure, though his fenfes 

 \vere unaffected by the ftimuli of vifible or audible 

 obje&s ; or fo weakly excited by them as not to 

 produce fenfation or attention. And the pleafure 

 thus excited by volition produced other ideas and 

 other motions in confequence of the tentbrial power 

 of fenfation. Whence the mixed catenations of vo^ 

 luntary and fenfitive ideas and mufcular motions in 

 reverie ; which, like every other kind of vehement 

 exertion, contribute to relieve pain, by expending a 

 {arge quantity of fenforial power. 



Thofe fits geneialiy commence during fieep, from, 

 whence I fuppofe they have been thought to have, 

 fome connection with ileep, and have thence been 

 termed Somnambulifm ; but their commencement 

 during ileep is owing to our increafed excitability 

 by internal fenfations at that time, as explained in 

 Sect XVIII. 14 and 15, and nof to any fimilitude 

 between reverie and deep. 



3. I was once concerned for a very elegant and 

 ingenious young lady, who had a reverie on alter- 

 nate days, which continued nearly the whole day ; 

 and as in her days of difeafe (lie took up the fame 

 kind of ideas, which (he had convened about on the 

 alternate day before, and could recollecl nothing of 

 them on her well-day ; fhe appeared to her friend $ 

 to poffefs two minds. This cafe alfo was of epi- 

 leptic kind, and was cured, with fome relapfes, by 



ppium.
