common convulfion, in the patient's pofTefllng at the fame time a 

 fenfibility of the ftimuli of external objects. 



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- 

 lifm confifting in the exertions of the locomotive mufcles, and 

 reverie in the exertions of the organs of fenfe , See Clafs I. I . 

 j. 9. and Seel. XIX. both which are mixed, or alternate with 

 each other for the purpofc 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 fael and imagiriation in their difcourfe ; but may be 

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

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

 fyinptoms 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 a confiftency in the trains of ideas.

The hallucinatio ftudiofa, 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.
