Under the word MAGDALEN, we find Webster superior to Worcester. Under ULAN, we find them both wrong. Dr. Worcester says it means "a species of militia among the modern Tartars"; and Dr. Webster, "a certain description of militia among the modern Tartars." In any Polish dictionary they would have found the word defined as meaning "lancer," and the Uhlans in the Austrian army can hardly be described as modern Tartar militia. Both Dictionaries give SLAW, and neither explains it rightly. The word does not properly belong in an English dictionary, unless as an American provincialism of very narrow range. As such, it will be found, properly defined, in Mr. Bartlett's excellent Vocabulary. Lexicographers who so often cite the Dutch equivalents of English words should own Dutch dictionaries. Under IMAGINATION, a good kind of test-word, we find Worcester much superior to Webster, especially in illustrative citations.

We have been astonished by some instances of slovenly writing to be found here and there in Dr. Webster's Dictionary, because he was capable of writing pure and vigorous English. Under MAGAZINE (and by the way, Dr. Webster's definition omits altogether the metaphorical sense of the word) we read that "The first publication of this bind in England was the Gentleman's Magazine, which first appeared in 1731, under the name of Sylvanus Urban, by Edward Cave, and which is still continued." A reader who knew nothing about the facts would be puzzled to say what the name of the new periodical really was, whether Gentleman's Magazine or Sylvanus Urban; and a reader who knew little about English would be led to think that "appeared by" was equivalent to "was commenced by," unless, indeed, he came to the conclusion that its apparition took place in the neighborhood of some cavern known by the name of Edward.

We have only a word to say as to the illustrations, as they are called, a mistaken profuseness in which disfigures both Dictionaries, another evil result of bookselling competition. The greater part of them, especially those in Webster, are fitter for a child's scrap-book than for a volume intended to go into a student's library. Such adjuncts seem to us allowable only, if at all, somewhat as they were introduced by Blunt in his "Glossographia," to make terms of heraldry more easily comprehensible. They might be admitted to save trouble in describing geometrical figures, or in explaining certain of the more frequently occurring terms in architecture and mechanics, but beyond this they are childish. The publishers of Webster give us all the coats-of-arms of the States of the American Union, among other equally impertinent woodcuts. We enter a protest against the whole thing, as an equally unfair imputation on the taste and the standard of judgment of intelligent Americans. If we must have illustrations, let them be strictly so, and not primer-pictures. Both Dictionaries give us the figure of a crossbow, for instance, as if there could be anywhere a boy of ten years old who did not know the implement, at least under its other name of bow-gun. Neither cut would give the slightest notion of the thing as a weapon, nor of the mode in which it was wound up and let off. Dr. Worcester says that it was intended "for shooting arrows," which is not strictly correct, since the proper name of the missile it discharged was bolt,—something very unlike the shaft used by ordinary bowmen.

We believe Dr. Worcester's Dictionary to be the most complete and accurate of any hitherto published. He intrudes no theories of his own as to pronunciation or orthography, but cites the opinions of the best authorities, and briefly adds his own where there is occasion. He is no bigot for the present spelling of certain classes of words, but gives them, as he should do, in the way they are written by educated men, at the same time expressing his belief that the drift of the language is toward a change, wherever he thinks such to be the case. We reprobate, in the name of literary decency, the methods which have been employed to give an unfair impression of his work, as if it had been compiled merely to supplant Webster, and as if the whole matter were a question of blind partisanship and prejudice. The assigning of such motives as these, even by implication, to such men, among many others, as Mr. Marsh and Mr. Bryant, both of whom have expressed themselves in favor of the new Dictionary, is an insult to American letters. Mr. Marsh, by the extent of his learning, is probably better qualified than any other man in America to pronounce judgment in such a case; and Mr. Bryant has not left it doubtful that he knows what pure and vigorous English is, whether in verse or prose, or that he could not employ it except to maintain a well-grounded conviction.

Apart from more general considerations, there are several reasons which would induce us to prefer Dr. Worcester's Dictionary. It has the great advantage, not only that it is constructed on sounder principles, as it seems to us, but that it is the latest. Stereotyping is an unfortunate invention, when it tends to perpetuate error or incompleteness, and already the Appendix of added words in Webster amounts to eighty pages. For all the words it contains, accordingly, the reader is put to double pains: he must first search the main body of the work, and then the supplement. Again, in Worcester, the synonymes are given, each under its proper head, in the main work; in Webster they form a separate treatise. One other advantage of Worcester would be conclusive with us, even were other things equal,—and that is the size of the type, and the greater clearness of the page, owing to the freshness of the stereotype-plates.

We know the inadequacy of such hand-to-mouth criticism as that of a monthly reviewer must be upon works demanding so minute an examination as a dictionary deserves. For ourselves, we should wish to own both Webster and Worcester, but, if we could possess only one, we should choose the latter. It is a monument to the industry, judgment, and accuracy of the author, of which he may well be proud.

Elements of Mechanics, for the Use of Colleges, Academies, and High Schools. By WILLIAM G. PECK, Professor of Mathematics, Columbia College. New York: A.S. Barnes & Burr. 1859.

Text-books on Mechanics are of three sorts. Many teachers, school-committees, and parents wish to add a taste of Mechanics to the smatterings of twenty or thirty different subjects which constitute "liberal education," as understood in American high schools and colleges. For this purpose it is of the first importance that the text-book should be brief, for the time to be devoted to it is very short; secondly, it must divest the subject of every perplexity and difficulty, that it may be readily understood by all young persons, though of small capacity and less application. Such a text-book can contain nothing beyond the statement, without proof, of the more important principles, illustrated by familiar examples, and simple explanations of the commonest phenomena of motion, and of the machines and mechanical forces used in the arts. To a few it seems that more light comes into a room through two or three broad windows, though they be all on one side, than through fifty bull's-eyes, scattered on every wall. But the many prefer bull's-eyes,—fifty narrow, distorted glimpses in as many directions, rather than a broad, clear view of the heavens and the earth in one direction. Hence superficial, scanty text-books on science are the only ones which are popular and salable.

The thorough study of Mechanics is, or should be, an essential part of the training of an architect, an engineer, or a machinist; and there are several text-books, like Weisbach's Mechanics and Engineering, intended for students preparing for any of these professions, which are complete mathematical treatises upon the subject. Such text-books are invaluable; they become standard works, and win for their authors a well-deserved reputation.

Professor Peck's book belongs to neither of the two classes of text-books indicated, but to a class intermediate between the two. It is at once too good, too difficult a book for general, popular use, and too incomplete for the purposes of the professional student. As it assumes that the student is already acquainted with the elements of Algebra, Trigonometry, Analytic Geometry, and the Calculus, the successful use of this text-book in the general classes of any academy or college will be good evidence that the Mathematics are there taught more thoroughly than is usual in this country. In few American colleges is the study of the Calculus required of all students. In preparing a scientific text-book of this sort, originality is neither aimed at nor required. A judicious selection of materials, correct translation from the excellent French and German hand-books, with such changes in the notation as will better adapt it for American use, and a clear, logical arrangement are the chief merits of such a treatise; and these are merits which seldom gain much praise, though their absence would expose the author to censure. The definitions of Professor Peck's book are exact and concise, every proposition is rigidly demonstrated, and the illustrations and descriptions are brief, pointed, and intelligible. Professor Peck says in the Preface, that the book was prepared "to supply a want felt by the author when engaged in teaching Natural Philosophy to college classes"; but surely a teacher who prepares a text-book for his own classes must need a double share of patience and zeal. Every error which the book contains will be exposed, and the author will have ample opportunity to repent of all the inaccuracies which may have crept into his work. Again, the instructor who uses his own text-book encounters, besides the inevitable monotony of teaching the same subject year after year, the additional weariness of finding in the pages of his text-book no mind but his own, which he has read so often and with so little satisfaction. Even in teaching Mechanics, there is no exception to the general rule, that two heads are better than one.
