i THE TONER LECTURES. 



quite awake, and then ask if there was anybody in the room 

 whom he had not previously seen,, who the person was, and 

 why he was not introduced to him ; being all the time in a 

 state quite different from that of wakefulness. He had seen 

 me many times, and knew me very well. Being with him once 

 when one of these attacks occurred, he lifted his head and 

 asked his mother, "Who is that gentleman?' Why don't you 

 introduce him to me?" His mother introduced me. He did 

 not know me at all. He shook hands with me, and then I had 

 a conversation with him, such as a physician may have with a 

 patient. In another instance, when with him again, while he 

 had the same kind of an attack, I found that he recognized me 

 fully, and talked of what we had spoken of in our first inter- 

 view. I ascertained from what I witnessed myself, and from 

 what I obtained from his mother, a very intelligent woman, that 

 he had in reality two lives, two mental lives, one in his ordinary 

 state, and another occurring after those attacks of a kind of 

 sleep for about a minute or two, when he knew nothing of what 

 existed in his other state — in his ordinary life ; that was all a 

 blank. He knew nothing during that second state but what 

 had occurred in previous periods of that same condition, but he 

 knew full well all that had occurred then ; and his recollection 

 of everything was as perfect then as it was during his ordinary 

 life concerning the customary acts of that state. He had, 

 therefore, as I have said already, two absolutely distinct lives, 

 in each of which he knew everything that belonged to its 

 wakeful period ; and in neither of which did he know anything 

 of what had occurred in the other. He remained in his abnormal 

 state for a time, which was extremely variable, between one and 

 three or four hours, and after that he fell asleep, and passed 

 out of that state of mind pretty much in the same way that he 

 had gone into it. I have seen three other cases of this kind, 

 and as so many have fallen under the observation of a single 

 medical practitioner, such cases cannot be extremely rare.
