The reaction of the nervous system was, no doubt, similar to that arising from delirium tremens; and thus extremes met, and the _savant_ perished like the inebriate. The tragedy did not seem complete until another victim should be added. The professor took the revolver to Thompson's, on Leith Walk, in order to learn by examination how many shots had been fired by the unfortunate suicide. The gunsmith took the weapon, but handled it so carelessly, that it went off in his hands, and the ball caused his death. Speaking of excessive labor, we may observe that this is the general rule among men of science or letters. They are, as a class, crushed by engagements and duties, as well as by problems and questions of which the world can not even dream. The Edinburgh literati know but little of rest or recreation; from the editor's chair up to the pulpit, they are under a lash as relentless as that of the taskmaster of Egypt. For instance, we might refer to Buchanan, of the _Mercury_. He has sat at his desk until he has become an old man, with the smallest imaginable subtraction of time for food and sleep, writing night and day, and carrying, in his comprehensive brain, the whole details of an influential journal. This feature, however, is not confined to the Old World, and may easily be paralleled in the journalism of America. Both Raymond, of the _Times_, and Bennett, of the _Herald_, almost live in the editorial function; and the former of these, though now Speaker of the Assembly, will either pen his leaders in his desk, during the utterance of prosy speeches, or in hours stolen from sleep after adjournment. In addition to these, we might quote the caustic language of Mr. Greeley, in reference to some mechanics who had 'struck,' in order to reduce their day's labor (we think to nine hours). 'He was in favor of short days of work, and having labored eighteen hours per diem for nearly twenty years, he was now going to "strike" for fifteen during the rest of his life.' But I doubt the success of Mr. Greeley's 'strike,' and apprehend that his early application has continued with but little abatement.
