 ous information of its pain having been complained of ; be- 

 caufe the pain of the tooth ceafes, as foon as the exertions of in- 

 fancy commence. In this cafe falivation might be tried. 



When a perfon becomes infane, who has a family of fmall 

 children to folicit his attention, the prognoftic is very unfavour- 

 able ; as it fhews the maniacal hallucination to be more pow- 

 erful than thofe ideas which generally intereft us the mod. 



When an infane young man (hews no lafcivious idea, when 

 an opportunity of gratifying the pailion of love is prelented to 

 him, as in the cafe above mentioned of Z. Z. or when an in- 

 fane young lady mews no fymptom of attachment, when ad- 

 drefled honouraoly by a proper lover, the prognoftic is unfa- 

 vourable, as it fhews the maniacal haiijcination to affect the 

 mind ftronger than the natural pailion of love, which in civilized 

 fociety is ftrengthened by reftraint. 



Paralytic affections are faid by Mr. Hafiam, to be frequently 

 fucceeded by infanity, and that in thefe cafes the inactivity of 

 fome paralytic mufcles about the face or limbs with defective 

 memory continue along with the infanity ; and he adds that thefe 

 patients are feldom relieved. Obiervations on Infanity by J. 

 Hallam, 8vo. Rivington. It was before obferved, that when 

 fome limbs become paralytic, as in the common hemiplegia, 

 that the other limbs are liable to be for fome time in aimoft per-e 

 petual action, owing to the fuperfluity of volition, which was 

 previoufly expended by the action of thofe mufcies, which are 

 now rendered difobedient to the fenforial power of volition, 

 though they may continue to be excitable by irritation or fenfa- 

 tion, as in the a<5t of pandiculation, or by electric {hocks. Now 

 if this fuperfluity of voluntary activity be exerted on the organs 

 of fenfe, delirious hallucinations and infane actions are the con- 

 fequence ; and as the power of life is already injured in a part 

 of the fyftem, they are lefs liable to recover, and die like other 

 paralytic patients. And thus the infanities in confequence of 

 paralytic affections, as well as thofe in confequence of pain- 

 ful fenfations or ideas, countenance the theory, that they 

 arife from the exceilive activity of the fenforial power of voli- 

 tion. 



2. Stadium inane. Reverie confifts of violent voluntary exer- 

 tions of ideas to relieve pain, with all the trains or tribes con- 

 nected with them by fenfations or alTociations. It frequently 

 alternates with epileptic convulfions ; with which it correfponds, 

 in refpect to the infenfibiiity of the mind to the ftimuli of ex- 

 ternal objects, in the fame manner as madnefs correfpoiuis with
