first scientifically formulated about twenty-five years ago, and was provided with one of those queer names which we now use more or less glibly, with a sort of comforting feeling that we understand the subject, when we have successfully mastered the spelling and pronunciation—the scientific name psycho-*therapeutics, or, in plain English, mind cure. These investigations were undertaken in France, to start with, at Nancy University, by Liébault, who published, in 1866, 'Treatment by Suggestion,' and by Bernheim, and simultaneously in Paris by Charcot, and they were primarily to observe sundry methods of treatment used at that time in an unscientific manner, such as animal magnetism, mesmerism, hypnotism, &c. Liébault's book, which was taken little notice of at the time, gave a full description of the methods he pursued, which more or less coincide with those followed by doctors who practise Treatment by Suggestion and Hypnotism at the present day. He lived a retired life, and practised entirely amongst the poor, who were devoted to him, but, at the same time, regarded him as an amiable enthusiast. Liébault finally retired on a very small competency, not acquired from his practice, which was altogether unremunerative.
