in hemicrania, unless by its apparent decay, or by some previous 

 information of its pain having been complained of; because the 

 pain of the tooth ceases, as soon as the exertions of insanity com- 

 mence. In this case salivation might be tried. 



When a person becomes insane, who has a family of small chil- 

 dren to solicit his attention, the prognostic is very unfavourable; 

 as it shews the maniacal hallucination to be more powerful than 

 those ideas which generally interest us the most. 



When an insane young man shews no lascivious idea, when 

 an opportunity of gratifying the passion of love is presented to 

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

 sane young lady shews no symptom of attachment, when address- 

 ed honourably by a proper lover, the prognostic is unfavourable, 

 as it shews the maniacal hallucination to affect the mind stronger 

 than the natural passion of love, vyhich in civilized society is 

 strengthened by restraint. 



Paralytic affections are said by Mi\ Haslam, to be frequently 

 succeeded by insanity, and that in these cases the inactivity of 

 some paralytic muscles about the face or limbs with defective 

 memory continue along with the insanity; and he adds that these 

 patients are seldom relieved. Observations on Insanity by J. 

 Haslam, 8vo. Rivington. It was before observed, that when 

 some limbs become paralytic, as in the common hemiplegia, 

 that the other limbs are liable to be for some time in almost per- 

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

 previously expended by the action of those muscles, which are 

 now rendered disobedient to the sensorial power of volition, 

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

 tion, as in the act of pandiculation, or by electric shocks. Now 

 if this superfluity of voluntary activity be exerted on the organs 

 of sense, delirious hallucinations and insane actions are the con- 

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

 of the system, they are less liable to recover, and die like other 

 paralytic patients. And thus the insanities in consequence of 

 paralytic affections, as well as those in consequence of pain- 

 ful sensations or ideas, countenance the theory, that they 

 arise from the excessive activity of the sensorial power of voli- 

 tion. 



2. Studium inane. Reverie consists of violent voluntary exer- 

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

 nected with them by sensations or associations. It frequently 

 alternates with epileptic convulsions; with which it corresponds, 

 in respect to the insensibility of the mind to the stimuli of ex- 

 ternal objects, in the same manner as madness corresponds with
