The present work, embracing the First Six Books of the Elements of Euclid, or in other words the foundation of Plane Geometry, is intended as a companion volume to that issued with it on Practical Geometry; the one embracing the theory, the other the application.

The text adopted is that of the distinguished mathematician, Dr. Simson. In very few instances has any change been made, and that only when it seemed to be positively necessary. Several attempts have been made, by altering the text and the arrangement, to reduce the demonstrations of Euclid to what may be considered a more popular form; but these have been attended with little success; and a text like that of Simson, clear, direct, and unencumbered, like absolute truth itself, will always be adopted by scholar and student.

It has been thought unnecessary to extend this volume beyond the first six books of the Elements, or to enlarge it by notes, as it will be followed by other works carrying the subject forward. A number of Exercises on each book have been given, the solutions of which will be published separately.

NOTICES OF THE PRESS.

We can have no hesitation in giving it as our decided opinion that this is the most elaborate and successful undertaking of the kind which has ever appeared."-Times.

"The very handsome volume before us, a beautifully-printed octavo of nearly 1500 pages, is a condensation of the two-volume quarto work of Dr. Webster. The single-volume version is taken from the last edition of the original work, with all its improvements and additions.

ILLUSTRATED EDUCATIONAL WORKS,

The plan of the abridgment is excellent; it contains the leading and most important etymologies as given in the quarto edition. The definitions remain unaltered, except by an occasional compression in their statement. All the significations of words, also, as exhibited in the larger work, remain unaltered; but the illustrations and authorities are only inserted in doubtful and disputed cases. It will be seen by this, that the smaller edition has been produced mainly by the very common-sense process of omitting the examples in the cases of undisputed and ordinary, or, at all events, not uncommon words, the authenticity and correctness of the definition of which nobody ever thinks of doubting. The richness of the treasury of words given is immense. It includes every possible scientific and artistic term; and the Doctor has been very liberal in inserting all those expressions adopted from the French, and commonly used in the upper circles of this country, as well as in recognising the semi-slangish expressions of familiarly colloquial life. The definitions are very clear, and quite devoid of Johnson's occasional pedantry; as, for example, let the reader turn up' the definition of network in both the dictionaries. The number of new words not to be found in other works of the same nature is immense; and in the preface it is asserted, and with truth, that thousands more could very easily have been added. The difficulty would appear to have been the selection. Thousands of words, it is remarked, can be found in dictionaries which have, indeed, been proposed, but never adopted in the language. These, as a general rule, Dr. Webster excludes; but he is careful to preserve those terms, once household words, and which have now fallen into disuse, but which were yet employed by the old standard writers, and a knowledge of which is necessary to understand some of the finest phases of our literature. A good many of the new words introduced are marked 'familiar,' 'colloquial,' or 'low.' The dictionary is rich in synonymsa very good feature-and one on which great care has been bestowed. To all who

wish for the most complete, cheap, and portable dictionary at this moment existing of our noble language, including an immense mass of philologic matter-copious vocabularies of mythologic, Scriptural, and geographic names-some curious dissertation as to the tendencies of orthography, and on the elements of the pronunciation of the principal continental languages-we can cordially recommend the beautifully printed and elaborately got-up volume before us."-Atlas.

"Professor Webster's English Dictionary has long become a standard English work, albeit the compiler was an American. The present volume is a revised edition of that great workfor such it strictly is-published in a cheap form. Originally given to the world in a quarto form, it was found before long, that an edition in a more compact shape was loudly called for; and accordingly, in the year 1829, Professor Worcester, of Cambridge, Massachussets, undertook its abbreviation and reduction, under the direction of Dr. Webster himself. The additions and alterations of the larger work (ed. 1840) were subsequently incorporated with the abbreviated edition; and this edition is the basis of the one now published by the proprietors of the Illustrated London Library.' It is consequently made, in all respects, consistent with the larger work; and it presents, accordingly, on a reduced scale, a clear, accurate, and full exhibition of the American dictionary in its every part.

"The meaning of every English word, in all its various shades, is given in this admirable work, which for completeness far excels the dictionary of Dr. Johnson; and it contains, moreover, a dictionary of synonyms, somewhat on the foundation of Carpenter's small publication, but more elaborately wrought and more fully treated. Under each of the important words, all others having the same general signification are arranged together, except in cases where they have been previously exhausted in framing the definitions-a system which is of the utmost importance to young writers desirous of attaining grace, variety, and copiousness of diction. "Some thousands of new words have been added to this vocabulary; but in justice to the compiler it should be stated that many of them are obsolete terms, employed by the writers of the Elizabethan period, but since their day fallen completely into disuse. The great bulk of these additions, however, consists of familiar and colloquial words and technical expressions necessitated by the establishment of novel occupations and new sources of ideas. The Americanisms, as such, are not so numerous as might be supposed; and the great bulk of them retained are shown to be old words with new meanings. All the scientific terms have been subjected to the strictest supervision on the part of competent persons; and so likewise have those of an artistic tendency. The result is such a dictionary as the English language has never had before; and which is as much superior to the last edition of Johnson's great work, even with all its improvements, as that stupendous production is to the moderate octavo of Bailey."-Observer.

"The advantage to the literary public of a cheap, enlarged, improved, and beautifully printed edition of a dictionary of our language, which has attained a considerable reputation, will be highly appreciated, and will serve very materially to assist its critical study. By dint of immense labour, continued during the space of three years, the editor of this fine volume was able to augment considerably the value of the original work, and in 1847 gave to the world the result of his extensive collations and emendations. Amongst the more remarkable features of this revised Dictionary may be mentioned that of its being a dictionary of synonyms, though not one in which, like Crabb's, nice shades of difference in the meaning of words are elaborately investigated. On the contrary, the practical force of each word is simply and accurately stated in such a manner as to leave no doubt or difficulty in selection. Great labour has been devoted to the perfection of the definitions, a subject in respect of which Webster's Dictionary from the first enjoyed a high reputation. In every branch of science, literature, art, and commercial economy, the best authors have been had recourse to, and their definitions extracted wherever necessary. In the course of the revision of the work some thousands of new words have been added, important alterations made in the orthography of peculiar words, to keep pace with the tendencies of our mode of writing, and particular care taken to exhibit, as perfectly as possible, the true pronunciation. Some supplementary vocabularies of classical names, and strictures on the right pronunciation of classical terms and names, complete the book, which, upon the whole, will be found a most valuable addition to the library of the most zealous reader. It contains 1300 large and rather closely-printed pages, and the typography is remarkably fine."-Morning Advertiser.
