BRAIN ASLEEP KEEPS TIME
wrapt in SIumber plan Hns Better Idea of Hour Than When
 Awake.


 That a man may have better idea of the time of night when he awakens from good sleep than he would have pf the time of day, provided he were working unusually hard, with unusual intentness of purpose, is one of the odd facts connected with the operation of the human brain, says the Chicago Tribune.
 But on the other hand, If a man may work with such intensity of purpose as to forget the lapse of two or three hours l of daylight, so he may sleep with a soundness that prevents the little time l keeper of the brain from making sub- conscious note of the hour hand of the clock in the night. AS between the two conditions, however, it is the opinion of Dr. o. A. King, professor of nervous dis eases in the College of Physicians and Surgeons, that the awakened sleeper usually has better idea of the flight of the night than the other may have of the flight of the day.
 Under ordinary circumstances the person who is in normal sleep is not | AONAA in the brain which takes cognizance Of time is alert to an extent not appreciated by the layman. Awakening at any time in the night the person in good health and condition knows pretty closely whether it is midnight or after, or whether 1t be nearer two o'clock dn the morning than it is to four o'clock. Many %I1 fon " that they know within the quarter hours of the exact time.
 "On the other hand it is a common ex- pression with persons in all line of work suddenly to look at the clock and ex- press the keenest surprise that 1t Is so late in the afternoon or the evening; and occasionally one who has been work ing to poor advantage and under dif- faculties will be surprised on looking at his watch that 1t is so early.
 ''That the brain in sleep keeps this tally upon the time is proved by the in- Huences of anaesthetics. A person who has been profoundly under the influence of any drug used for the purpose will be as utterly unconscious of the passing of ten minutes as he will be unconscious of the passing of an hour. He may be forgetful of all conditions leading up to the state of anaesthesia and for the time being he may have forgotten the day of the week.
 ''As to the time measurement in sleep, 1t is best represented in the person used to travel and to the catching of trains in the night. Many of these persons will be able to awaken at an hour giving them just the margin needed for preparation fer the train.
 f "One of the peculiarities of a persons gency, Is that the awakening always Is sudden. There Is none of the prelimi- nary yawning, and stretching, and slow ly returning sense of luxurious rest and comfort felt by the man who has slept a full sleep. In this awakening to a certain time the person frequently feels that impression of a sudden sound which he knows cannot have been made or uttered. Not infrequently he has the sense that some one has called his name. He may be almost certain that he has heard his first name-'George?'-c with the characteristic rising infection. In almost any case his awakening ia without any premonitory symptoms. It Is with a sort of jolt that he comes into full fledged consciousness. In such cases as those where the sleep is profound be-. yond any consciousness of the time, tho dream period of sleep Is left far behind; the sleep has approached the depth of anaesthesia."
 One of the oddities of sleep was referred rest without intending to sleep. It may be morning or afternoon, but the fatigue that prompts the person to lie down overcomes him, and, after sound sleep, he awakens without any knowledge of time in any sense. He does not realize whether it Is morning or afternoon; whether he has had luncheon, or wheth- CT he may not have slept through day and night, and awakened into another day It Is the opinion of pr. King thatin such case the person experiencing the sensations probably is not in normal state of health.
 AS an example of sleep that should be natural and close to the design of nature, and of an awakening that should be normal without the effect of an artificial civilization crowding it, the babe which has rested to the full and begins to arouse itself from slum Der Is an interest ing study.
