I remember, about three years ago, going with my husband to hear the lecturers of a person who called himself Professor R---. He had been lecturing for some nights running at the Mechanics' Institute for nothing; and had drawn together a great number of persons to hear him, and witness the strange things he effected by mesmerism on the persons of such of the audience, who wished to test his skill. This would have been but a poor way of getting his living. But these American adventurers never give their time and labour for nothing. He obtained two dollars for examining a head phrenologically, and drawing out a chart; and as his lectures seldom closed without securing him a great many heads for inspection, our disinterested professor contrived to pocket a great deal of money, and to find his cheap lectures an uncommonly profitable speculation. We had heard a great deal of his curing a blacksmith of _tic-douloureux_ by mesmerizing him. The blacksmith, though a big, burly man, had turned out an admirable clairvoyant, and by touching particular bumps in his cranium, the professor could make him sing, dance, and fight all in a breath, or transport him to California, and set him to picking gold. I was very curious to witness this man's conduct under his alleged mesmeric state, and went accordingly. After a long lecture, during which the professor put into a deep sleep a Kentuckian giant, who travelled with him, the blacksmith was called upon to satisfy the curiosity of the spectators. I happened to sit near this individual, and as he rose to comply with the vociferous demands of the audience, I shall never forget the sidelong knowing glance he cast across the bench to a friend of his own; it was, without exception, the most intelligent telegraphic despatch that it was possible for one human eye to convey to another, and said more plainly than words could--"You shall see how I can humbug them all." That look opened my eyes completely to the farce that was acting before me, and entering into the spirit of the scene, I must own that I enjoyed it amazingly. The blacksmith was mesmerised by a _look_ alone, and for half an hour went on in a most funny manner, keeping the spectators with their eyes open, and in convulsions of laughter. After a while, the professor left him to enjoy his mesmeric nap, and chose another subject, in the person of a man who had lectured a few nights before on the science of mnemonics, and had been disappointed in a very scanty attendance.
