What Comes Of Overwork

Before the New York Neurological Society last evening, Dr. E. C. Seguiii prpsiding, Dr. Wm. A. Hammond icad a paper on "Cerebro Hyperscrmia," Tbis De eaid, was quite a commou disease[ and was brought on generally ly bverintellectual exertion. The symptoms are vértigo, noises in the ears, dark spotR before tlie eyes, a staggeriug in the walk, numbness in the limbs and twitchingg or spasniB in the iace. There is a mental disturbance which is Bhown by hallucinationB, and principally by sleeplessness. Tlie digestión is impaired. These are the symptoms in violent coses. In general tüe patiënt is deprived almost wholly of sleep, r has unpleasant drcnnis. He finds it impossible to fix his attentioii on any subject, and i attacked by a pain in the head if he ranke a mental efïirf. An accurate accountant who was nt..tacked by this diseaso could not add op a column of figures, making saistakcs which in his normal condition he woukl consider ridiculous. Iu one caae reported a gentleman attempted to coma't suicide because he could not sol vo asimplo gum. The patiënt is forgetf ui of ñames and faces, and makes mistakes iu uring words. There is, too, a great deal o!. indecisión manifested in simple mattere.. "I knew a patiënt." Dr. Hamraonri said, " to carry several thousands of dollars every day for a montli to Wall etrett, intending to malee a certain epeculation, bxit every day he put it off without any reason whatever. There is a morbid apprehensión of impendmg evil, and tinpatiënt is afraid that he will himself commit 6ome dreadiul act. I have known of a man who dreaded to go on a ferry-bost becnuse he feared that he wouUl t'iroyr hims-elf off; of another who would nofi go Bear a tram, for f eer he wotil 1 tbrcw himself iu front of it; of a husband who made his wife keep his razors locked up; of a man who would not take a waiin bath, in the fear that he would not turn off the hot water. Tho subjf , however, never yields to these iiapnlfe?. The emotional system is deranged. Thr patiënt becomes suspioious and annoyed on the slightest grounds. A patiest once was liable to be attacked by vértigo at any time, bo that frequently andio the street he would have to support hinistlf by a lamp-post, or sit on a stoop until the attack was over. This vértigo is generally increased by mental elfort, and disappeara more or less when the patiënt is about to go to sleep. The ooulnr museles are easily tired, eo that the patiënt cannot read. Sometimes tlm sense of hearing ia very acute, and a: other times very dull. The disease is generally accompanied by congestión oí the tympanum, and the symptoms are: intensified by sulphate of quiniue aud other medicines, which nre somttimes given to patiënte who are suffering from this disease. The muscular streugtb is impaired so that the patiënt romt-times is uuable to lift his arm or his foot. "The causes of cerebro-hypertemia are. monta!. A young lady was once attacked by itin consequenee of au intense intellectual effort she pilt forth to sobe a mathematical problem. The diseiwft is more apt to attack those in middle life tlian the young or old. To be ured the pntiout shonld abstain from sevre mental work, should exerciee in the on air, indulge in moderate gayety and a ploio but uutritions diet. "
