VOL. I. SPANISH AND ENGLISH. VOL. II.- ENGLISH AND SPANISH.

Two Volumes, Royal Octavo, Sheep. Price, $3.75.

The present stereotype edition of this Spanish and English Dictionary has been carefully revised and enlarged by the addition of many thousand words extracted from the writings of the most classical Spanish and English authors, many of which are not to be found in any other dictionary of those languages, and also by great additions from the dictionaries of Connelly and Higgins, the Spanish Academy, &c., &c. It probably contains not only many more words than are to be found in the most copious vocabularies, but also much practical and useful information; more facts. principles, and terms now used in the sciences, arts, manufactures, and commerce, than in any similar dictionary hitherto published, and likewise more of the modern words in the polite or familiar conversation of both countries.

Nearly two hundred pages have been added to the volumes now presented to the public; and the space gained in the other portions of them, by lengthening the pages and compressing the definitions, so as to leave but few short lines, augments their contents to the equivalent of nearly four hundred pages more than the preceding editions of this work. In the Spanish-English, above three thousand entirely new articles have been introduced; in the English-Spanish, above twelve thousand.

ITALIAN POCKET

DICTIONARY:

IN TWO PARTS.

I. ITALIAN AND ENGLISH.-II. ENGLISH AND ITALIAN.

PRECEDED BY AN

ITALIAN GRAMMAR.

BY C. GRAGLIA.

FROM THE FOURTEENTH LONDON EDITION,
WITH CORRECTIONS AND ADDITIONS.

Finely Printed, in One Volume, 16mo, Sheep. Price, $1.35.

The general approbation with which this valuable little Dictionary has been received, the rapidity with which fourteen editions have been exhausted in England, and its universal adoption by instructors in this country, are a sufficient recommendation of this work. Many errors of accentuation, orthography, &c., had, however, found their way into the text, which has been carefully revised, and compared with those of Alberti, Barberi, &c.

In a Pocket Dictionary of so copious a language as the Italian, a complete vocabulary is not to be expected. In order to make the additions to this part of the work more useful, the texts of the classics most commonly read by beginners were examined, and such words and idioms inserted from them. amounting to about three thousand articles, as were not contained in the former editions.

SERIES OF MATHEMATICAL TEXT BOOKS.

BY WILLIAM SMYTH, A. M.,

PROFESSOR OF MATHEMATICS IN BOWDOIN COLLEGE.

1. — ELEMENTARY ALGEBRA.

This treatise is designed for beginners. The first principles of the science are familiarly explained, and applied to the investigation of the rules and solution of the questions of Arithmetic.

2.- TREATISE ON ALGEBRA.

This is an extended treatise on the subject, embracing the theory of the higher equations. With the following parts of the course it is designed for the use of Colleges and Schools.

3.- PLANE TRIGONOMETRY, SURVEYING, AND NAVIGATION.

The Trigonometry is developed in a manner to give a clear idea of the nature and use of the Trigonometrical Tables. The Surveying is designed to give a comprehensive view of the subject, embracing surveys of every extent, from the simple field to an extended territory, including also those required for Canal routes, Railroads, &c. The work contains the necessary Logarithmic and Trigonometrical Tables.

4. — ANALYTICAL GEOMETRY.

The design of this treatise is to explain the origin and true nature of Analytical Geometry; to show its adaptation to the investigation of the truths of Geometry, and thus to prepare the way for the introduction of the Calculus.

5.- ELEMENTS OF THE DIFFERENTIAL AND INTEGRAL CALCULUS.

In this treatise the student is led, by a very natural and easy process, to a general knowledge of the principles of the Calculus, to see in what it consists, and to discern its power, as the highest instrument of mathematical investigation.

All the parts of this Series of Elementary Works are arranged with reference to each other, and are adapted, it is believed, to conduct the student, with facility and advantage, over the wide extent of mathematical topics which it embraces.

SMITH'S GEOGRAPHIES.

FIRST BOOK OF GEOGRAPHY.

NEW PRIMARY GEOGRAPHY.
INTERMEDIATE GEOGRAPHY.

COMPREHENSIVE GEOGRAPHY,

BEING A CONCISE TREATISE ON PHYSICAL, ANCIENT AND MODERN.

The publishers are confident, knowing the results of frequent experiments, that a class of scholars using these works will acquire, in a given time, a marked increase of proficiency over those whose studies in Geography have been pursued according to the unsatisfactory plans of various other text books. This is the highest test of a school book, and to this SMITH'S GEOGRAPHIES have been repeatedly and successfully subjected.

SMITH'S ILLUSTRATED ASTRONOMY.

A new work, in quarto form, containing eighty pages, thirty-two of which are BEAUTIFUL DIAGRAMS, each illustrating some important principle in Astronomy- and, all together, giving most of the representable phenomena in this interesting science.

EXPLANATORY NOTES are placed upon the SAME PAGE with the Diagrams, and Lessons belonging to them on the PAGE OPPOSITE, so that the text and illustrations are before the eye at the same time.

The subject is treated in so definite and simple a manner that it can be comprehended by the most common reader, and any teacher can introduce this work into his school without having any previous knowledge of the science. It is a very interesting book for an adult to peruse on a long winter's evening, from which he may learn much of the sublime and wonderful works of Deity. It is one of the noblest of sciences, and should be familiar to every school and every family.

Its extensive sale has been such as to prove it the MOST POPULAR WORK ON ASTRONOMY yet published. It has been introduced generally into the schools and academies throughout the UNITED STATES AND CANADAS, receiving the most unqualified commendations. The author has just revised it, and brought it up to the present time, adding the discoveries which have been made within the past few years. It is printed from new Electrotype Plates, which give the Diagrams a very clear and beautiful appearance.

SMITH'S ABRIDGED ASTRONOMY.

MAYHEW'S PRACTICAL BOOK-KEEPING.

A SYSTEM OF PRACTICAL BOOK-KEEPING, BY SINGLE AND DOUBLE ENTRY.

WITH A SET OF ACCOUNT BOOKS,

To be used by the Learner in writing the Examples for Practice contained in the Bon!: Keeping, and a Key for Teachers, containing their Solution.

BY IRA MAYHEW, A. M.,

Author of a Treatise on "Popular Education," and State Superintendent of

Public Instruction in Michigan.

45-49,1853-59

"Most of the treatises heretofore published have been either meagre and insufficient, or in the other extreme, quite too profound, and adapted only to the wants of our higher Schools and Academies. MAYHEW'S PRACTICAL BOOK-KEEPING, however, happily avoiding both these extremes, is a thorough treatise, yet so simplified as to be fully within the comprehension of all intermediate classes in our Common Schools. This work will be found to fill an important niche that has long been unoccupied. It is not only adapted to the wants of Schools, but should be in the hands not only of the merchant, but the artisan and the farmer, (to whom ample space is allotted.) and every person in the land. It is eminently suggestive, and every person taking it for his guide, will soon find all his affairs arranged in a clear, business-like manner." - Granville High School Journal.
