GUMMERE'S ASTRONOMY. $3.25.

AN ELEMENTARY TREATISE ON ASTRONOMY, in Two Parts: the first containing a clear and compendious View of the Theory; the second, a number of Practical Problems. To which are added Solar, Lunar, and other Astronomical Tables. By John Gummere, A. M., &c. &c. Sixth Edition, revised and adapted to the present state of the science, by E. Otis Kendall, A. M., Professor of Mathematics and Astronomy in the Central High School of Philadelphia.

The call for a sixth edition of this work, the sale of more than five thousand copies, and its use, for some years past, as a text-book, in many collegiate institutions of the first rank in the United States (e. g. the U. S. Military Academy at West Point, Union College, the University of Pennsylvania, Wesleyan University, and the Public High School of Philadelphia,) would seem to render commendation unnecessary, to establish its claims to the favorable consideration of instructors; but the names of the two gentlemen whose opinions are appended, as well as their qualifications to judge of the merits of the work, are so weil known, that the publishers are induced to add the weight of these opinions to the already firmly established reputation of the work.

From Professor A. D. Bache, LL. D., Superintendent U. S. Coast Survey. The undersigned, having used the second edition of Gummere's Astronomy as a text-book in the University of Pennsylvania for several years, and a third edition for a year, when last connected with the University, has had a good opportunity to judge of its merits, and recommends it strongly for its clear style and perspicuous arrangement. The Appendix to the third edition contains matter of the highest interest to the practical astronomer as well as to the student. A. D. BACHE, Late Prof. of Natural Philosophy, Univ. of Pa.

Extract from a Letter to the Author.

RESPECTED FRIEND-In returning to you my thanks for the copy of your work, I am
happy in having it in my power to bear testimony to the favourable opinion which the late
Dr. Bowditch entertained of the merits of the former edition. When I first engaged in as-
tronomical computations, some years ago, I applied to the doctor for some direction as to the
choice of suitable practical books. He was not without those European preferences so com
mon to our scientific men, yet, without hesitation, he pronounced "Gummere's Astronomy"
the best book obtainable for my purpose. Since then, it has been one of my principal guide-
books, and one which I have always taken a pleasure in recommending to those wishing to
become acquainted with the science, &c.
Respectfully, your friend,
NOVEMBER 28th, 1813.

MONGE'S STATICS. $1.25.

AN ELEMENTARY TREATISE ON STATICS, by Gaspard

Monge. With a biographical notice of the Author. Translated from the French, by Woods
-Baker, A. M., of the United States Coast Survey.

The original work has long been known and highly admired by those familiar with the
Scientific literature of France, having gone through eight editions at Paris and several at
Brussels. Prof. A. D. Bache designates it "the classic of the geometrical method, and well
adapted to the use of the students in our Colleges, Academies and High Schools." Prot.
McCulloh, of Princeton College, says, "I have long thought that the publication of a trans-
iation of the admirable Elementary Treatise on Statics of Monge would render important
service to the cause of science and education in our country: the original work is above all
need of praise; the production of a great master, yet so perfectly clear and simple as to be
of easy comprehension to the minds even of children, and as thorough as it is plain" in
which opinion, Prof. Kendall, of the Central High School of Philadelphia concurs; and Prof.
J. F. Frazer, of the University of Pennsylvania, writes: "I am glad to learn that you are
about to publish a translation of Monge's Elementary Treatise on Statics. It is a work dis-
tinguished by the clearness of its method and the simplicity and general elegance of its
demonstrations; and will, in my opinion, be of great value to our instructors as a text-book."
The work has been adopted as a text-book for the Senior and Junior classes of Princeton
College.

M'MURTRIE'S SCIENTIFIC LEXICON. 75 cta.

A TEXT-BOOK IN THE CENTRAL HIGH SCHOOL OF PHILADELPHIA.

LEXICON SCIENTIARUM. A DICTIONARY OF TERMS used in the various branches of Anatomy, Astronomy, Botany, Geology, Geometry, Hygiene, Mineralogy, Natural Philosophy, Physiology, Zoology, &c. By Henry M Murtrie, M. D., etc, Professor of Anatomy, Physiology, and Natural History, in the Central High School of Philadelphia.

From Samuel George Morton, M. D., Vice-President of the Academy of Natural Sciences, of
Philadelphia; formerly President of the Association of American Geologists and Naturalists,
author of "Crania Americana," "Crania Egyptica," &c. &c.

I have examined Dr. M'Murtrie's Dictionary of Scientific Terms, and believe it to be ad
mirably adapted to the explanation of the numerous technicalities that are inseparably
connected with every department of Science. Such a glossary is indeed indispensable to the
learner, who by its aid will find every step facilitated and much time saved.
PHILADELPHIA, October 27, 1847.

SAMUEL GEORGE MORTON.

From M. II. Boyè, Professor of Chemistry in the Central High School, Philadelphia, dic.
Laboratory, at Old Mint,
PHILADELPHIA, October 19, 1847.

I have been much pleased with Dr. M Murtrie's Scientific Dictionary. Such a work has
been long needed to enable the student to acquire a correct knowledge of the derivation
and meaning of the various scientific terms: It will also be found very convenient to more
advanced scholars, as a book of reference. I therefore take great pleasure in recommend-
ing it to the public in general.

Designed as a text-book for Schools and Academies, and Colleges, as well as for private reading. By Charles D. Cleveland. Fourteenth Thousand.

This work has been extensively introduced, as a text-book, in Public High and Normal Schools, and in Colleges, Female Seminaries, Academies, and private Seminaries, throughout the United States. [Price $1.50.]

From Rev. John Ludiow, D. D., Provost of the University of Pennsylvania.

The public are greatly indebted to you for placing before our youth this Compendium of
English Literature. I hope it will command the attention which it certainly deserves; and
if my name would have any influence, I would most earnestly recommend it to every young
lady especially, who desires a "finished" education.

Departing from my usual custom, if you or your publishers should deem this note of any
use to extend the circulation of your valuable work, it is heartily at your service.
UNIVERSITY OF PENNA, January 13, 1848.
JOHN LUDLOW.

From Professor Goodrich, of Yale College.

I have read Professor Cleveland's "Compendium of English Literature" with lively inte-
rest. The selections are made with uncommon taste and judgment. The biographical
notices and critical estimates prefixed to the extracts appear to me accurate and discrimi-
nating, and they certainly add much to the interest of the work, which supplies a want
that has long been felt, and which must, I think, when known, be deemed an almost indis-
pensable auxiliary in the highest classes of our schools and academies, in the study of
English Literature.
CHAUNCEY A. GOODRICH.

NEW HAVEN, January 20, 1848.

From Rev. Charles B. Haddock, D. D., Professor of Intellectual Philosophy and English
Literature in Dartmouth College.

"MY DEAR SIR-I have read your Compendium with great satisfaction and delight. It
a work much needed, and exceedingly well executed. The plan is, so far as I know,
quite original; the biographical sketches are judicious and elegantly written; and the
selection of authors, and of passages from their works, in an eminent degree fitted to into
duce the student to the most finished and most wholesome portions of our Literature-the
richest, noblest Literature the world has yet produced.”

CLEVELAND'S

ENGLISH LITERATURE OF THE 19th CENTURY.

ENGLISH LITERATURE OF THE NINETEENTH CENTURY, Chronologically Arranged. Consisting of biographical sketches of the authors and selections from their works; with notes explanatory, illustrative, and directing to the best editions and various criticisms; being a sequel to the "Compendium of English Literature." De signed as a text-book for Colleges, Academies and the highest classes in other schools. By Charles D. Cleveland. [See notice of Stereotype Edition, appended. [Price $1.50.]

The extensive use of the "Compendium of English Literature" in schools, throughout the United States, and the high commendation which it has received from the leading peri odicals of England, assure the publishers that the present volume, which, in its general plan, is similar, and, in the list of authors, probably more attractive to readers generally, will meet the favor of those desirous to promote a refined literary taste in the rising generation.

HARRISON ON THE ENGLISH LANGUAGE. $1.

THE RISE, PROGRESS, AND PRESENT STRUCTURE OF THE English Language. By the Rev. Matthew Harrison, A. M., Rector of Church Oakley, Hants, and late Fellow of Queen's College, Oxford.

OPINIONS OF THE PRESS.

"Rarely have we been more disappointed-favourably, we mean-than by the examina tion of this handsome volume. Instead of another abortive attempt to improve on Lindley Murray, which we expected to find, we found a most entertaining and instructive work on the gradual rise and development of the English language, containing an historical sketch of the various tribes and people who have occupied Britain at different times, and showing the various tongues which have contributed to make up the medley which we call the English language. The manner in which this has been done is explained by numerous examples, and the genius and character of the English language are described; the sources of corruption are designated; the present structure of the language is very thoroughly explained, and the construction of the different parts of speech, and their nature and use, illustrated by pertinent examples. Take it all in all, the volume before us contains more valuable, readable-yea, and entertaining-matter, than any work we have met with for many a day."-Boston Daily Evening Traveller.

"A work of a class of which English literature has very few, and of which there is necessity for very many.... Mr. Harrison's book affords capital hints against lack of precision and failure in effect.... It is curious and entertaining enough to be put on the parlor table."-Literary World, New York.

"We commend it to the favorable attention of the lovers of a language in which the cause of liberty is to be pleaded throughout the world."—N. Y. Observer.

"Altogether, the book is a delightful one. Designed mainly for schools and colleges, it will yet find its way into the libraries of men of letters and men of taste, and will do much to correct the growing faults of style in many modern writers.... It is in every respect an admirable volume, which, for the sake of the language we love, we trust may have a very extensive circulation."--Evening Bulletin, Philadelphia.

"It should be in the possession of every teacher or public speaker or writer in the land.”— Model American Courier, Philadelphia.

CLEVELAND'S HYMNS FOR SCHOOLS. 37 cts.

HYMNS FOR SCHOOLS; with appropriate Selections from Scripture, and Tunes suited to the metres of the hymns. By Charles D. Cleveland. Second edition, revised and improved.

In this little volume are grouped together the choicest sacred lyrics of our language; there being one for each day in the year, and additional hymns for special occasions. Each hymn is prefaced by an appropriate Scripture-text; and the notes of a number of tunes are appended, whose beauty has kept them popular, notwithstanding the love of change which RO generally prevails. In this edition, also, the names of the authors of the hymns are given, which to many readers will add interest to the volume.

From Professor Brégy, of the Philadelphia Central High School.

PHILADELPHIA, January 24, 1848. GENTLEMEN-No better idea could have been suggested to you than that of republishing this work of Berquin.

Among the French popular writers he occupies a place secondary to no one; the purity of his style is unsurpassed, and he has been properly called the Historian of Young age, which he pictures both as it is and should be.

The morality of all his works tends to awake the noblest and purest sentiments of the mind.
With my best wishes for the success of the work, should you publish it,
F. A. BREGY.

I remain yours, most respectfully,
