colour is his coat ?" He replied, " A drab colour." " And 

 what buttons ?" " Metal ones," he anfwered, and added, " how 

 fadly his legs are fwelled." In a few minutes he faid, with ap- 

 parent furprife, " He is gone/' and returned to his perfect mind. 

 Other cafes are related in Seel: XIX. and XXXIV. 3. and in 

 Clais III. 1. 2. 2. with further obfervations on this kind of 

 hallucination j which however is not the caufe of reverie, but 

 conftitutes a part of it, the caufe being generally fome uneafy 

 fenfation of the body. 



3. Vigilia. Watchfulnefs confifls in the unceafing exertion 

 of volition 5 which is generally caufed by fome degree of pain 

 either of mind or of body, or from defect, of the ufual quantity 

 of pleafurable fenfation ; hence if thole, who are accullomed to 

 wine at night, take tea inftead, they cannot fleep. The fame 

 happens from want of folid food for fupper, to thofe who are 

 accullomed to ufe it ; as in thefe cafes there is pain or defect of 

 pleafure in the ftomach. 



Sometimes the anxiety about fleeping, that is the defire to 

 fleep, prevents fleep ; which confifts in an abolition of defire or 

 will. This may fo far be compared to the impediment of fpeech 

 defcribed in Sect. XVII. 1. 10. as the interference of the will 

 prevents the effect defired. 



Another fource of watchfulnefs may be from the too great 

 fecretion of fenforial power in the brain, as in phrenzy, and as 

 fometimes happens from the exhibition of opium, and of wine ; 

 if the exhauftion of fenforial power by the general actions of the 

 fyftem occafioned by the flimulus of thefe drugs can be fuppo- 

 fed to be lefs than the increafed fecretion of it. 



M. M. 1 . Solid food to fupper. Wine. Opium. Warm 

 bath. 2. The patient (hould be told that his want of fleep is of 

 no confequence to his health. 3. Venefection by cupping. Ab- 

 flinence from wine. 4. A blifter by (timulating the fkin, and 

 rhubarb by (timulating the bowels, will fometimes induce fleep. 

 Exercife. An uniform found, as of a paufing drop of water, 

 or the murmur of bees. Other means are defcribed in Sect:. 

 XVIII. 20. 



4. Erotomania. Sentimental love. Defcribed in its excefs 

 by romance writers and poets. As the object of love is beauty, 

 and as our perception of beauty confifts in a recognition by the 

 fenfe of vifion of thofe objects, which have before infpired our 

 love, by the pleafure they have afforded to many of our fenfes 

 (Sect. XVI. 6) j and as brute animals have lefs accuracy of 

 their f^n(c of vifion than mankind (ib.) ; we fee the reafon why 

 this kind of love is not frequently obfervable in the brute crea- 

 tionj eicept perhaps in fome married birds, or in the affection of
