194 OF DRUNKENNESS. SECT. XXL 5. 



ceed ; and the trains of ideas become more and more inconfift- 

 ent from this defect of voluntary exertion, as explained in the 

 fections on fleep and reverie, whilft thofe paffions which are un- 

 mixed with volition are more vividly felt, and (hewn with lefs 

 referve ; hence pining love, or fuperftitious fear, and the maud- 

 iing tear dropped on the remembrance of the mod trifling 

 diftrefs. 



5. At length all thefe circumftances are increafed ; the quan- 

 tity of pleafure introduced into the fyftem by the increafed irrita- 

 tive mufcular motion of the whole fanguiferous, and glandular, 

 and abforbent fyflems, becomes fo great, that the organs of fenfe 

 are more forcibly excited into action by this internal pleafurable 

 fenfation, than by the irritation from the ftimulus of external 

 objects. Hence the drunkard ceafes to attend to external ftimu- 

 li, and as volition is now alfo fufpended, the trains of his ideas 

 become totally inconfiflent as in dreams, or delirium : and at 

 length a ftupor fucceeds from the great exhauftion of fenforial 

 power, which probably does not even admit of dreams, and in 

 which, as in apoplexy, no motions continue but thofe from in- 

 ternal ftimuli, from fenfation, and from aflbciation. 



6. In other people a paroxyfm of drunkennefs has another ter- 

 mination ; the inebriate, as foon as he begins to be vertiginous, 

 makes pale urine in great quantities and very frequently, and at 

 length becomes lick, vomits repeatedly, or purges, or has pn> 

 fufe fweats, and a temporary fever enfues with a quick ftrong 

 pulfe. This in fome hours is fucceeded by fleep ; but the un- 

 fortunate bacchanalian does not perfectly recover himfelf till 

 about the fame time of the fucceeding day, when his courfe of 

 inebriation began. As fhewn in Sect. XVII. I. 7, on Catena- 

 tion. The temporary fever with ftrong pulfe is owing to the 

 fame caufe as the glow on the fkin mentioned in the third para- 

 graph of this Section : the flow of urine and ficknefs arife from 

 the whole fyftem of irritative motions being thrown into confu- 

 fion by their aflbciations with each other as in fea-ficknefs, 

 mentioned in Sect, XX. 4. on Vertigo , and which is more fully 

 explained in Section XXIX. on Diabetes. 



7. In this vertigo from internal caufes we fee objects double, 

 as two candles inftead of one, which is thus explained. Two 

 lines drawn through the axis of our two eyes meet at the object 

 we attend to : this angle of the optic axi.s increafes or diminifhes 

 with the lefs or greater diftances of objects. All objects before 

 or behind the place where this angle is formed, appear double ; 

 as any one may obferve by holding up a pen between his eyes 

 and the candle ; when he looks attentively at a fpot on the pen, 

 and careiefsly at the candle, it will appear double $ and the re- 



verfe
