from the Mathematics of LACROIX and Bézouт. Translated from the French for the use of the students of the University at Cambridge, New England. Second edition. 8vo. Price $1,50.

The treatises upon Plane and Spherical Trigonometry, though concise, are abundantly sufficient for all the ordinary purposes to which they are applied. The portion on Conic Sections developes the leading properties of these curves in a very plain and satisfactory manner.

Although the analytical method is adopted it will be found to be attended with little or no difficulty. The immense advantages which it gives over the geometrical cannot but be perceived by the diligent and faithful student. New steps are supplied and all the aid to be derived from frequent references, are afforded, that the less experienced learner may proceed with as much dispatch as the nature of the subject will admit. The formulas in Trigonometry and Conic Sections which will be sought in vain in the common treatises will be found to be of the greatest importance in the higher parts of Natural Philosophy and especially in Astronomy.

An ELEMENTARY TREATISE on the Application of Trigonometry to Orthographic and Stereographic Projection, Dialling, Mensuration of Heights and Distances, Navigation, Nautical Astronomy, Surveying and Levelling; together with Logarithmic and other Tables; designed for the use of the students of the University at Cambridge, New England. 8vo. Price $2,00. (This work is lettered Topography.)

The several parts of this volume are prepared with great care; the best English and French works were consulted and no pains spared in condensing into a small compass what was deemed most important relating to the topics here treated. The Logarithmic tables are from the stereotype plates of BoWDITCH's Practical Navigator, the correctness of which is too well known to need any recommendation.

FIRST PRINCIPLES of the DIFFERENTIAL and INTEGRAL CALCULUS, or the Doctrine of Fluxions, intended as an Introduction to the Physico-Mathematical Sciences; taken chiefly from the Mathematics of Bézouт. And translated from the French for the use of the students of the University at Cambridge, New England. 8vo. Price $1,50. This will be found far more easy and satisfactory than the English treatises upon this subject. It was selected on account of the plain and perspicuous manner for which the author is so well known, as also on account of its brevity and adaptation in other respects to the wants of those who have but little time to devote to such studies.

An ELEMENTARY TREATISE on MECHANICS, comprehending the Doctrine of Equilibrium and Motion, as adapted to Solids and Fluids, chiefly compiled, and designed for the use of the students of the University at Cambridge, New England. By JOHN FARRAR, Professor of Mathematics and Natural Philosophy. 8vo. Price $4,00.

Under the term Mechanics, are comprehended, in this work, not only those topics which are usually treated under this name, but also Hydrostatics and Pneumatics. The leading propositions are demonstrated with great strictness, and are derived one after another from a very few fundamental principles. There is throughout particular reference to the practical uses of the science.

ELEMENTS of ELECTRICITY, MAGNETISM, and ELECTRO-MAGNETISM, embracing the late Discoveries and Improvements, digested into the form of a Treatise; being the Second Part of a Course of Natural Philosophy, compiled for the use of the students of the University at Cambridge, New England. By JOHN FARRAR, Professor of Mathematics and Natural Philosophy. 8vo. Price $3,50.

Many phenomena and theories are made known in this treatise that the reader will seek in vain in the best English works on these subjects.

An EXPERIMENTAL TREATISE on OPTICS, comprehending the Leading Principles of the Science, and an explanation of the more important and curious Optical Instruments and Optical Phenomena, being the Third Part of a Course of Natural Philosophy, compiled for the use of the

Students of the University at Cambridge, New England. By JOHN FARRAR, Professor of Mathematics and Natural Philosophy. 8vo. Price $3,00. This treatise is mostly confined to what is capable of being established and illustrated by experiment. In the Notes to this and the foregoing volume are collected many recently discovered facts and principles that have not yet been embodied into the form of a treatise.

An ELEMENTARY TREATISE on ASTRONOMY, adapted to the Present Improved state of the Science, being the Fourth Part of a Course of Natural Philosophy, compiled for the use of the students of the University at Cambridge, New England. By JOHN FARRAR, Professor of Mathematics and Natural Philosophy. 8vo. Price $3,75.

This is a plain and familiar view of the subject. It is intended to be at once popular and profound. A great part of it may be read without difficulty by persons little skilled in the pure Mathematics; other parts will require more attention and study and somewhat more aid from the subsidiary sciences.

ELEMENTS of NATURAL PHILOSOPHY. By E. G. FisCHER, Honorary Member of the Academy of Sciences of Berlin, Professor of Mathematics and Natural Philosophy in one of the Colleges of the same city, &c. &c. Translated into French, with Notes and Additions, by M. BIOT, of the Institute of France; and now translated from the French into English for the use of Colleges and Schools in the United States. Edited by JOHN FARRAR, Professor of Mathematics and Natural Philosophy in the University at Cambridge, New England. 8vo. Price $3,00.

This is an ingenious compend of Mechanical and Physical Philosophy that has been much used and highly approved in the German and French schools.

The GREEK READER, by FREDERICK JACOBS, Professor of the Gymnasium at Gotha, and Editor of the Anthologia. From the last German edition, adapted to BUTTMANN'S Greek Grammar. Second Boston edition. 1 vol. 8vo. Price $2,25.

Extract from the North American Review.

The Greek Reader, having been compiled by one of the leading scholars of the age, is prepared throughout in a pure and masterly manner; proceeds methodically from the simplest combination of words to the common attic style; and is so composed, that while the rules of grammar are illustrated in easy succession, an outline is given of mythology, ancient geography, and Grecian history. It is used in almost all the good schools in Germany, and has there gained a decided expression of public opinion in its favor, as the best of the many similar works, which have been produced by the scholars of that prolific country.

In regard to the American edition, the chief question concerns its accuracy; and this quality it possesses in an eminent degree. As the Notes and Lexicon are in English, it affords the means of learning Greek without the embarrassing intervention of another foreign tongue. That it contains references to the American translation of BUTTMANN's Grammar, will make it the more valuable to those who possess that work, without diminishing its utility for those, who continue to use the more ancient manuals.

Preface to the Second Boston Edition.

This edition of the Greek Reader has been prepared with great care. The Lexicon has been revised by a scholar of distinguished accuracy, and great pains have been bestowed in inserting such words and significations of words, as had accidentally been omitted in the first edition, and in making other improvements in conformity with the suggestions of experienced instructers. In the typographical execution of the work, the traces of a diligent and skillful revision of the press will probably be perceived. The text has undergone a thorough revision, having been collated with the German edition of this work, as well as compared with some approved edition of the several authors from whom the extracts are taken; and the references to the Grammar have been accommodated to the second edition of BUTTMANN's Grammar.

At a meeting of the Corporation of Harvard College,

Voted, "That this work be made use of in examining candidates for admission into the University after the year 1826, instead of Græca Minora."

DEUTSCHES LESEBUCH für Anfänger, i. e. German Reader

for Beginners. Edited by Dr. CHARLES FOLLEN, of Harvard University. 1 vol. Price $1,25.

The design of this book is expressed in the Preface. It is intended to meet an urgent want of all those who are engaged either in teaching or studying the German language in this country. It introduces the learner to the master works of modern German literature, and furnishes the teacher with a large number of classical examples, to illustrate the rules and peculiarities of the language.' The book is divided into a prosaic, and a poetical part. The prosaic part contains, in chronological order, select pieces from the works of Lesing, Wieland, Herder, Engel, Göthe, Johannes, Müller, Schiller, Heeren, A. W. Schlegel, F. Schlegel, Wackenroder, Hardenberg, Tieck, and Hoffmann. The poetical part exhibits specimens of various kinds of poetry, by Schiller, Göthe, Bürger, Herder, Tieck, and Körner.

A sketch of the history of German literature from the earliest times to the present, is contained in the Preface.

"This is one of the pleasantest and best selections we are acquainted with, for the purpose of introducing a beginner to the knowledge of a foreign language. The object of it, as stated in the preface, is to give a collection of examples illustrative of the rules and peculiarities of the language, from works of acknowledged classical rank, and at the same time to afford the learner a foretaste of the modern German literature. This object is, we think, well attained; and though a task of no very formidable nature, yet it is one not unworthy of the attention of the learned scholar who has prepared the book, and to whom we are indebted for contributing his efforts to increase the means of cultivating one of the most useful and important languages of the present day."-North American Review.

In Press. A PRACTICAL GRAMMAR of the German Language, by Dr. CHARLES FOLLEN, Instructer of the German Language at Harvard University, Cambridge. 12mo.

This work is calculated to serve as a guide to the teacher; as well as to those who wish to study the German language without the aid of an instructer. The author has consulted the most important grammatical works which have heretofore been published, on the continent of Europe, and in England; with particular reference to the grammars of Heinsius, Noehden, and Rowbotham. He has endeavored to comprise in his grammar all that seemed to him really useful for acquiring a practical knowledge of the German language; without entering into too minute details, or indulging in idle speculations. Every rule of the language is illustrated by examples, and exercises for translating from German into English, and from English into German. The pronunciation is facilitated by an analysis of all the sounds which belong to the German language, and by marking the accent of every word which occurs in this Grammar.

GOULD'S VIRGIL, with English Notes, and a Key for Scanning. Publius Virgilius Maro. Bucolica, Georgica, et neis. Accedunt Clavis Metrica, Notulæ Anglica, et Quæstiones, nec non Index vocabulorum Uberrima. Cura B. A. GOULD. In Usum Scholæ Bostoniensis. 8vo. Price $3,50.

This edition of Virgil is printed without the usual order of construction, or interpretation. The use of these pernicious helps not only prevents the pupil from ever acquiring the power of reading with ease and pleasure without them, but it is utterly subversive of one of the principal objects of studying the language,—that mental discipline which is acquired by the practice of critical and exact analysis. If the habit of reading independently of artificial assistance be once formed, the want of such assistance is not felt. And it is found by experience that boys who have never used an order or interpretation, read Horace and Juvenal, as readily as they do Cicero and Tacitus; and even with more confidence; since they are aided by Prosody in overcoming many doubts in poetry, which they have no means of solving in prose. The use of the interpretation is discontinued in the best schools both in England and in this country; as is also the absurd custom of explaining by Latin notes, which boys do not understand.

To aid the scholar in overcoming the real difficulties in understanding this author, copious English notes are added at the end. A list of the verses most difficult to scan is subjoined, with the method of scanning each. A few questions are also added, which may expedite the labor of the teacher in ascertaining whether the pupil has been thorough in his preparations.

The work is published on a fine paper, and beautiful type; and is, altogether, far superior to any other edition of Virgil in use.

Extracts from the North American Review. No. 52.

It is printed with great neatness, in a type of sufficient size, producing well defined, well filled, well rounded letters, such as the eye may dwell upon without pain or weariness. We are acquainted with no edition, which, as regards typography, the accuracy of the text, and the correctness of punctuation, we should believe, will be read with more satisfaction. We rejoice to find this edition of Virgil excluding the order of construction, or the interpretation, which has so long disfigured our school Virgil, and other Latin poets. This interpretation, and translations into English of similar demerit, have often been the miserable crutches by which boys have limped their weary way through the Æneid, wholly unsuspicious that they were in company with one of the greatest poets of ancient or modern times.

The notes are various in their kind; and not among the least frequent or useful are those of a philological character. The editor will not be accused of superfluity or prolixness in this part of his work; and his reasons for brevity are such as every person of similar experience will accept without hesitation.

National Gazette and Literary Register. July 13, 1827.

Mr. GOULD has rendered much service to the ends of classical education in this country, by his editions of Virgil and Adam's Latin Grammar, and his Excerpta from Ovid, with Notes and Questions. The Virgil, in particular, deserves to be widely known, from the peculiar correctness of the text, which is substantially Heyne's, the variations from that, the best extant, being slight, and such only as a careful collation of all the acknowledged authorities appeared to require.

Both the Virgil and the Ovid are printed not merely with remarkable accuracy, but in a handsome form. Whatever is well done in this way promotes, or supports the cause of classical literature and the good old system of instruction, which are assailed in public opinion by empirical speculations and schemes of "tricking short cuts and little fallacious facilities." Of the many contemporary innovations with regard to the communication of knowledge and the general culture of the mind, they are but very few which deserve to be styled improvements.

GOULD'S GRAMMAR :—ADAM'S LATIN GRAMMAR, with some Improvements, and the following Additions: Rules for the Right Pronunciation of the Latin Language; a Metrical Key to the Odes of Horace; a List of Latin Authors arranged according to the different ages of Roman Literature; Tables, showing the value of the various Coins, Weights, and Measures, used among the Romans. By BENJAMIN A. GOULD, Master of the Public Latin School, Boston. Price, bound, $1,00.

"It must be remembered that if the Grammar be the first book put into the learner's hands, it should be the last to leave them."-Preface to BUTTMANN'S Greek Grammar.

This edition is adopted by the University at Cambridge, Massachusetts, and is recommended to the use of those who are preparing for that Seminary.

Extracts from the Journal of Education.

Mr. GOULD has in this edition of the Grammar rendered to classical instruction one of the most valuable services it has hitherto received in this country. His endeavors to promote a uniform and correct pronunciation of Latin are an important addition to the value of the Grammar.

The acquisition of a correct pronunciation should be an object of attention, as early as possible in the course of instruction.

With regard to the general merits of the rules we need say nothing, after stating that they are sanctioned by the authority of our most reputable literary institutions.

On one circumstance, connected with the improved edition of ADAM's Latin Grammar, we congratulate every instructer. The care taken to accent penultimate syllables seems likely to succeed in banishing the hideous mispronunciations with which our School and College exercises were, and are sometimes disgraced.

We cannot take leave of this valuable school book without expressing our warmest approbation of it, and our gratitude for the facilities which its editor has afforded our youth for their progress in a language which is essential to a full understanding of their own; which is the avenue to professional life, and to the highest and most honored spheres of public usefulness.

GOULD'S OVID, with English Notes. Excerpta ex scriptis Publii Ovidii Nasonis. Accedunt Notulæ Anglicæ et Quæstiones. In usum

Scholæ Bostoniensis. This selection embraces portions of the Metamorphoses, Epistles, and Fasti. 8vo. Price $1,25.

Extracts from the Preface.

In preparing this little volume from the writings of Ovid, great care has been taken to admit nothing in the slightest degree indelicate, or improper for the study of youth. One object has been to furnish examples of the different kinds of measure used by this polished and fascinating writer. It is not a little surprising that in the whole course of studies preparatory for, and pursued at our Colleges, not a verse of pentameter measure occurs. This is the more surprising, since, in addition to the frequency of its use, this kind of versification may be considered one of the most easy and graceful which the ancient poets used.

As this book is designed for a kind of introduction to fabulous history, the notes give a more full account of the subjects connected with the matter immediately under consideration, than might otherwise seem expedient.

The questions are designed to direct the student's attention to the subjects of the notes, as well as to those of the text; for a knowledge of the characters here introduced will generally facilitate a proper understanding of all subsequent studies in Latin and Greek.

Extracts from the United States Review and Literary Gazette, for August, 1827. As in his Virgil, so in these selections from Ovid, Mr. GOULD has rejected the order of construction and the interpretation and for reasons, we think, perfectly satisfactory. The Notes, too, [in English] are of the same judicious character as those in his Virgil. And besides those which are intended to assist the pupil merely in the business of interpreting the author, many of them are devoted to the explanations of names which occur so frequently in the Metamorphoses, and which have so much to do with the fabulous history of ancient times.

The Questions annexed are well adapted to direct the pupil's attention to what is most worthy of his notice, and thus to fix in his memory many important facts in ancient mythology, and history, and geography.

We cannot close our remarks without expressing our obligations to Mr. GOULD for this additional contribution to the cause of good learning. While we look not only with complacency, but with great satisfaction, upon the various useful enterprises that engage the busy world about us, we are delighted occasionally to greet the scholar, who comes to take the rising generation by the hand, and make them familiarly acquainted with the favorite poets of ancient times.

GOULD'S HORACE, with English Notes. Quinti Horatii Flacci Opera: accedunt clavis metrica et notulæ Anglica, Juventuti accommodatæ. Cura B. A. GOULD. 12mo.

This edition of Horace has been prepared with much care for the use of young gentlemen at School and at College; and of course is free from all indelicacies. It is of the duodecimo form, and of a size convenient for use, with the notes at the end. The notes are concise, and adapted to the degree of information which the student is supposed to possess at that stage of his classical education when this author is usually studied. It is presumed that most students have become acquainted with the leading characters in classical history and mythology before they take Horace. For this reason the notes are chiefly confined to the illustration of the text, i. e. the peculiarities of this author, and to such explanations of the manners and customs of the time, and of the characters introduced, as seem necessary to a right understanding of the poet's allusions.

GRAGLIA'S NEW POCKET DICTIONARY of the Italian and English Languages. With a compendious Elementary Italian Grammar, from the last London edition. (Now Stereotyping.)

The general approbation, with which the numerous editions of this valuable little Dictionary, have been received;-the rapidity, with which fourteen editions of it have been exhausted in England;-and its universal adoption by the instructers of the Italian language in this country, are a sufficient recommendation of the work and a proof of its superiority to others compiled on the same plan. "Several attempts," says the preface to the fourteenth London edition, "have been made to surpass this Dictionary; but it still keeps up its advantages and the last edition was sold in half the time of the preceding one."

The vocabulary is copious and various, the definitions accurate, many difficult phrases and peculiar idioms explained, and the most common poetical terms, which often occasion so much embarrassment to beginners, are introduced and defined. Numerous re-publications have, however, been made at London, without a proper
