common convuifion, in the patient's pofiefling at the fame time a 

 fenfibility of the (timuli of external objecls. 



Some have been reported to have been involved in reverie fo 

 perfectly, as not to have been dilturbed by the difcharge of a 

 cannon ; and others to have been infenfible to torture, as the 

 martyrs for religious opinions ; but thefe feem more properly 

 to belong to particular infanities than to reverie, like noftalgia 

 and erotomania. 



Reverie is diftinguifhed from madnefs as defcribed above ; 

 and from delirium, becaufe the trains of ideas are kept confid- 

 ent by the power of volition, as the perfon reafons and delib- 

 erates in it. Somnambulifmus is a part of reverie, fomnambu- 

 iifm confiding in the exertions of the locomotive mufcles, and 

 reverie in the exertions of the organs of fenfe ; See Oafs I. 1 . 

 1. 9. and Sect. XIX. both which are mixed, or alternate with 

 each other for the purpofe of relieving pain. 



When the patients in reverie exert their volition on their or- 

 gans of fenfe, they can occafionally perceive the ftimuli of ex- 

 ternal objects, as explained in Seel:. XIX. And in this cafe it 

 refembles fometimes an hallucination of the fenfes, as there is a 

 mixture of fact and imagination in their difcourfe ; but may be 

 thus diflineuifhed : hallucinations of the fenfes are allied to de- 

 lirium, and are attended generally with quick pulfe, and other 

 fymptoms of great debility;' but reverie is without fever, and 

 generally alternates with convulfions *, and fo much intuitive 

 analogy (fee Seel:. XVII. 3. 7-)is retained in its paroxyfms, as to 

 preferve s confiftency in the trains of ideas.

The hallucinatio ihidiofa, or falfe ideas in reverie, differ 

 from maniacal hallucinations above defcribed, as no infane ex- 

 ertions fucceed, and in the patients whom I have feen they 

 have always been totally forgotten, when the paroxyfm was 

 over.
