This edition of a favourite Dictionary has been, as correctly stated, thoroughly revised and greatly enlarged, with the pronunciation, accentuation, and derivation of the terms. There are close upon 1,200 pages, and the amount of laborious revision which the progress of knowledge demands is enormous. Absolute perfection in such a work cannot be demanded of an editor, and no doubt slight inaccuracies have been allowed to pass uncorrected in the work before us. For example, the first meaning of “Braidism” is given as “animal magnetism.” Everyone knows, or rather ought to know, that this is precisely what it is not, and that, in fact, Braidism or hypnotism was a determined protest against animal magnetism. The same regrettable mistake is made under “Hypnotism,” which is defined as produced “through the influence of animal magnetism.” There may be other instances of confusion among the innumerable definitions contained in this massive volume. We have looked up a number of words, and have found an extraordinary mass of information, fully justifying the statement made by the editor.
