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

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

 sadly his legs are swelled." In a few minutes he said, with ap- 

 parent surprise, " He is gone," and returned to his perfect mind. 

 Other cases are related in Sect. XIX. and XXXIV. 3. and in 

 Class III. 1. 2. 2. with further observations on this kind of hal- 

 lucination; which however is not the cause of reverie, but con- 

 stitutes a part of it, the cause being generally some uneasy sensa- 

 tion of the body. 



3. Figilia. Watchfulness consists in the unceasing exertion 

 of volition; which is generally caused by some degree of pain 

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

 pleasurable sensation; hence if those who are accustomed to 

 wine at night, take tea instead, they cannot sleep. The same 

 happens from want of solid food for supper, to those who are ac- 

 customed to use it; as in these cases there is pain or defect of 

 pleasure in the stomach. 



Sometimes the anxiety about sleeping, that is, the desire to 

 sleep, prevents sleep; which consists in an abolition of desire or 

 will. This may so far be compared to the impediment of speech 

 described in Sect. XVII. 1.10. as the interference of the will 

 prevents the effect desired. 



Another source of watchfulness may be from the too great se- 

 cretion of sensorial power in the brain, as in phrenzy, and as 

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

 if the exhaustion of sensorial power by the general actions of the 

 system occasioned by the stimulus of these drugs can be supposed 

 to be less than the increased secretion of it. 



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

 bath. 2. The patient should be told that his want of sleep i* of 

 no consequence to his health. 3. Venesection by cupping. Ab- 

 stinence from wine. 4. A blister by stimulating the skin, and 

 rhubarb by stimulating the bowels, will sometimes induce sleep. 

 Exercise. An uniform sound, as of a pausing drop of water, 

 or the murmur of bees. Other means are described in Sect. 

 XVIII. 20. 



4. Erotomania. Sentimental love. Described in its excess 

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

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

 sense of vision of those objects, which have before inspired our 

 love, by the pleasure they have afforded to many of our senses 

 (Sect. XVI. 6.); and as .brute animals have less accuracy of 

 their sense of vision than mankind (ib.); we see the reason why 

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

 tion, except perhaps in some married birds, or in the affection of
