6 SO SLEEP- WAKING. 



to another, dejected, saying innocent, but absurd, rude, though 

 often witty and droll, things, which showed her feelings to be 

 disturbed, incoherent, and mimicking admirably, whistling and 

 singing well ; and picking paper or linen to pieces : at length in 

 her attacks she occasionally swore, and was amorous. After re- 

 maining in this condition for a few days, she suddenly by mesmeric 

 manipulations one evening became herself completely ; still com- 

 plaining of pain at the top of her head, which she had suffered 

 from for many months and for which I had bled her repeat- 

 edly. She afterwards suddenly fell into this delirium again 

 several times, and, after continuing in it some hours or days, 

 would by mesmeric manipulations in two or three seconds become 

 completely herself and remain so for some hours or days. To ob- 

 serve her picking paper or linen to pieces, talking incoherently, 

 now whistling aloud, now singing in the ward, cross, miserable, 

 rude, dancing about, unable to look steadily for many seconds, her 

 eyes converging from parallelism, her countenance pale, and 

 expressive now of insanity, now of fatuity; and then in two or three 

 seconds to see her completely herself, smiling, perfectly rational, 

 amiable, well behaved, with an expression of great intelligence, 

 was one of the most extraordinary changes I ever witnessed ; to 

 see the functions of the brain in many points nearly suspended, 

 in many over excited, and in many wrong, the organ altogether 

 oppressed and deranged, and then righting itself and perform- 

 ing all its functions properly in an instant, made an impression 

 upon me never to be effaced. When not in an attack, she forgot 

 every thing that had occurred in her attacks : but, when in them, 

 she recollected the occurrences of preceding attacks. In the 

 delirium her hands were not always cold as in the sleep-waking. 

 The pulse appeared hardly affected. 



I will relate a number of examples of sleep-waking to show the 

 various amount and extent of activity in this condition. 



This first is very similar to that of my own patient, but sleep- 

 walking was added in one stage of the paroxysm. 



" At Berlin," says Gall, " a young man, sixteen years old, had 

 extraordinary attacks from time to time. He was agitated in 

 his bed without consciousness ; his movements and gestures 

 showed a great activity of many internal organs ; whatever was 

 done to him, he did not perceive it; at length he jumped out of 

 bed, and walked hastily in the apartment : his eyes were then
