carious state of health; and it was only as his health became more con- 

 firmed, that the sound of the bugle gradually left him." ( Abercrombie. ) 



Dr. Sam Johnson relates that he once heard the voice of his absent 

 mother distinctly call his name, " Sam! " "A lady, whom I attended 

 some years ago, in a slight, feverish disorder, saw distinctl} T a party of 

 ladies and gentlemen sitting round her bedchamber, and a servant hand- 

 ing something to them on a tray. The scene continued in a greater or 

 less degree for several days, and was varied by spectacles of castles and 

 churches of a very brilliant appearance, as if they had been built of 

 finely cut crystal. The whole was in this case entirely a visual phan- 

 tasm, for there was no hallucination of mind. On the contrary, the 

 patient had, from the first, a full impression that it was a morbid affec- 

 tion of vision connected with the fever, and amused herself and her 

 attendants by watching and describing the changes in the scenery. 



"A gentleman, who was also a patient of mine, of an irritable habit, 

 and liable to a variety of uneasy sensations in his head, was sitting 

 alone in his dining-room in the twilight, the door of the room being a 

 little open. He saw distinctly a female figure enter, wrapped in a 

 mantle, and the face concealed by a large, black bonnet. She seemed 

 to advance a few steps towards him and then stop. He had a full con- 

 viction that the figure was an illusion of vision, and amused himself for 

 some time by watching ; at the same time, observing that he could see 

 through the figure so as to perceive the lock of the door, and other 

 objects behind it. At length, when he moved his body a little for- 

 ward, it disappeared. " (Abercrombie.) 



Although there was no "hallucination of mind" in these two cases, 

 nevertheless, it is probable the trouble was in some part of the cerebral 

 memory tract. A sort of delirium affected certain organs by which the 

 images were revived, while the rest of the organs, not being unduly 

 erethised, received true representations from the environment, and gave 

 true perceptions which contradicted and corrected the false ones given 

 by the other internal sense organs. 



When we dream, a portion of the organs are thus excited, and give 

 sensations of more or less connected memories, and they seem to us 

 real, because the rest of the organs, including the external senses, are 

 dormant and do not furnish any corrective or contradictory perceptions. 

 In these two cases, the internal senses furnished the data for the spec- 

 tral illusions, while the external senses furnished true reports of what 

 there was in sight, which contradicted and corrected the others ; and 

 that is why there was no "hallucination of the mind." And yet, what- 

 ever hallucination there was, was of some of the internal senses, and 

 not of the organs of sensation.
