Mr. Braid has selected a neat motto for his treatise, for the matter contained in it will hardly warrant the assumption of a more ambitious title.

Mr. Braid, of Burlington House, Manchester, a doctor by profession, is a believer in and exponent of hypnotism. A great portion of his little work reviews the criticisms on earlier editions, or deals with statements regarding Colquhoun's 'History of Magic.' Its author, while rejecting the doctrines known as animal mesmerism and magnetism, admits the effects they are declared to produce; but he refers such results to hypnotism—a state of induced sleep—into which a patient may be thrown by artificial contrivance.

It is possible that the contents of this book would not prove of much general interest excepting to amateurs of 'animal magnetism;' but we give one extract, which may prove of service to those who do not happen to be already informed of the theory it advances, which is one that every reader can practically test:—

'In my work on hypnotism,' observes Mr. Braid, 'published in 1843, I explained how "tired nature's sweet restorer, balmy sleep," might be procured, in many instances, through a most simple device, by the patient himself. All that is required for this purpose is simply to place himself in a comfortable posture in bed, and then to close the eyelids, and turn up the eyeballs gently, as if looking at a distant object, such as an imaginary star, situated somewhat above and behind the forehead, giving the whole concentrated attention of the mind to the idea of maintaining a steady view of the star, and breathing softly, as if in profound attention, the mind at the same time yielding to the idea that sleep will ensue, and to the tendency to somnolence which will creep upon him whilst engaged in this act of fixed attention. Mr. Walker's method of "procuring sleep at will," by desiring the patient to maintain a fixed act of attention by imagining himself watching his breath issuing slowly from his nostrils, after having placed his body in a comfortable position in bed, which was first published by Dr. Binns, is essentially the same as my own method, &c.'

Professor Gregory, in his 'Letters to a Candid Inquirer,' after describing the induction of sleep effected by reading a class of books of a dry character, remarks: 'But let these persons (sufferers from a difficulty in getting off to sleep) try the experiment of placing a small bright object, seen by the reflection of a safe and distant light, in such a position that the eyes are strained a little upwards or backwards, and at such a distance as to give a tendency to squinting, and they will probably never again have recourse to the venerable authors above alluded to. Sir David Brewster, who, with more than youthful ardour, never fails to investigate any curious fact connected with the eye, has not only seen Mr. Braid operate, but has also himself often adopted this method of inducing sleep, and compares it to the feeling we have when, after severe and long-continued bodily exertion, we sit or lie down and fall asleep, being overcome, in a most agreeable manner, by the solicitations of Morpheus, to which, at such times, we have a positive pleasure in yielding, however inappropriate the scene of our slumbers.'
