PROF. MANDEVILLE'S READING BOOKS.

I. PRIMARY, OR FIRST READER. Price 10 cents.
II. SECOND READEN. Price 16 cents.

T'hese two Readers are formed substantially on the same plan; an the second is a continue vion of the first. The design of both is, to combine a knowledge of the meaning and prononnia. vion of words, with a knowledge of their grammatical functions. The parts of speech are in po uced successively, beginning with the articles, these are followed by the Lemonstrative pro. porns; and these again by others, class after class, until all that are requisite to forn a sentence buvo been separately considered; when the common reading lessons begin.

The Second Reader reviews the ground passed over in ihe Primary, but adds largely in the winount of information. The child is here also taught to read wriung as well as printeil inatter; and in the reading lessons, attention is constantly directed to the dillerent ways in which sentences are formed and connected, and of the peculiar manner in which each of them is deliv ered. All who have examined these books, have pronounced them a decided and important ad Vance on every other of the same class in use.

II. TIIRD READER. Price 25 cents.
IV. FOURTH READER. Price 38 cents.

In the first two Readers, the main object is to make the pupil acquainted with the mea.ing and functions of words, and to impart facility in pronouncing them in sentential conection: the leading design of these, is to form a natural, flexible, and varied delivery. Accordingly, the Third Reader opens with a series of exercises on articulation and modulation, containing numer ous examples for practice on the elementary sounds (including errors to be corrected) and on the different movements of the voice, produced by sentential structure, by emphasis, and by the pas sions. The habits formed by these exercises, which should be thoroughly, as they can be easily mastered, under intelligent instruction, find scope for improvement and confirmation in the reading lessons which follow, in the same book and that which succeeds.

These lessons have been selected with special reference to the following peculiarities : Ist Colloquial character; 2d, Variety of sentential structure; 3d, Variety of subject matter; 4th Adaptation to the progressive development of the pupil's mind; and, as far as possible, 5th Tendency to excite moral and religious emotions. Great pains have been taken to make the booky in these respects, which are, in fact, characteristic of the whole series, superior to any oihers in use; with what success, a brief comparison will readily show.

V THE FIFTH READER; OR, COURSE OF READING. Price 75 cents.
VI THE ELEMENTS OF READING AND ORATORY. Price $1.

These books are designed to cultivate the literary taste, as well as the understanding and voca. powers of the pupil.

The Course or READING comprises three parts; the first part containing a more elaborate description of elementary sounds and the parts of speech grammatically considered than was deemed necessary in the preceding works; here indispensable : part second, a complete classifi. cation and description of every sentence to be found in the English, or any other language; ex. amples of which in every degree of expansion, from a few words to the half of an octavo page in length, are adduced, and arranged to be read; and as each species has its peculiar delivery an well as structure, both are learned at the same time; part third, paragraphs; or sentences in thei: conne-tion unfolding general thoughts, as in the common reading books. It may be obs. serval that we selections of sentences in part second, and of paragraphs in part third, comprise some of the finest gems in the language : distinguished alike for beauty of thought and facility of diction. If not found in a school book, they might be approprately called “ elegant extracis"

The ELEMENTS.OP READING AND ORATORY closes the series with an exhibition of the whole theory and art of Elocution exclusive of gesture. It contains, besides the classification of sen tences already referreu is, but here presented with fuller statement and illustration, the laws of punctuation and delivery deduced from it: the whole followed by carefully selected pieces for seutential analysis and vocal practice.

THE RESULT.-The student who acquaints himself thoroughly with the contenus of thin book, will, as numerous experiments have proved; Ist, Acquire complete knowledge of the structure of the language; 2d, Ba able to designate any sentence of any book by name at a glence; 34, Be able to declare with equal rapidity its proper pur.ctuation; 4th, Be able to de are, and with sufficient practice to give its proper delivery. Such are a few of the general character 16tics of the series of school books which the publishers now offer to the friends and patrone of a sound common school and academic education. For more particular information, reference is respectfully made to the “Hints," which may be found at the beginning of each volume.

N. B. The punctuation in all these books conforms, in the main, to the sense and proper de livery of every sentence, and is a guide to both. When a departure from the proper punctuation occurs, the proper delivery is indicated. As reading books are usually punctuated, it is a matter of surprise that children should learn to read at all.

...The above series of Reading Books are already very extensively introduced and com mended by tne most experienced Teachers in the country. “Prof. Mandeville's system is em: dently original, scientific and practical, and destined wherever it is introduced to superhede at once all others."

COURSE OF MATHEMATICAL WORKS,

BY GEORGE R. PERKINS, A. Muy
Professor of Mathematics and Principal of the State Normal School

I. PRIMARY ARITHMETIC. Price 21 cts.
A want, with young pupils, or rapidity and accuracy in performing operations upon writtej
um ers; an imperfect knowledge of Numeration; ina lequate conceptions of the nature an
relations of Fractions, and a lack of familiarity with the principles of Decimals, have induced
the author to prepare the PRIMARY ARITHMETIC.

The tirs: part is devoted to MENTAL EXERCISES and the second to Exercises on the Slate
and Blackboard.

While the minds of young pupils are disciplined by mental exercises (if not wearisomely
prolonged), they fail, in general, in trusting to head.work" for their calculatior"; und in re.
sorting to written operations to solve their difficulties, are often slow and inaccurate from a want
of early familiarity with such processes: these considerations have induced the Author to devote
part oi his book to primary written erercises.
It has been received with more popularity than any Arithmetic helt.ofore issues

II. ELEMENTARY ARITHMETIC. Price 42 cts.
Has recently been carefully revised and enlarged. It will be found concise, yet lucid. It icaches
the radical relations of numbers, and presenis fundamental principles in analysis and examples.
Il leaves nothing obscure, yet it does not embarrass by multiplied processes, nor e..leeble by
minute details.

In this work all of the examples or problems are strictly practical, made up as they are in a
great measure of important statistics and valuable facis in history and philosophy, which are
thus unconsciously learned in acquiring a knowledge of the Arithmetic.

Fractions are placed immediaiely alter Division ; Federal Money is treated as and with De-
cimal Fractions; Proportion is placed before Fellowship, Alligation, and such rules as require
its application in their solution. Every rule is marked with verity and simplicity. The an-
swers to all of the examples are given.

The work will be found to be an improvement on most, if not all, previous eleinentary
Arithmetics in the treatment of Fractions, Denominate Numbers, Rule of Three, Interest, Equa.
uon of Payments, Extraction of Roots, and many other subjects.

Wherever this work is presented, the publishers have heard but one opinion in regard to its
merits, and that most favorable.

III. HIGHER ARITHMETIC. Price 84 cts.
The present edition has been revised, many subjects rewritten, and much new matter added;
and contains an APPENDIX of about 60 pages, in which the philosophy of the more difficut
operations and interesting properties of numbers are fully discussed. The work is what its naine
purports, a Higher Arithmetic, and will be found to contain many entirely new principles which
have never before appeared in any Arithmetic. It has received the strongest recoin lendations
from hi pdreds of the best teachers the country afforis.

IV. ELEMENTS OF ALGEBRA. Price 84 cts,
This work is an introduction to the Author's “ Treatise on Algebra," and is designed espo
cially for the use of Commor. S:hools, and universally pronounced “admirably adapted to the
purpose."

V. TREATISE ON ALGEBRA. Price $1 50.
This work contains the higher parts of Algebra usually taught in Colleges ; a new method
of cubic and higher equation as vell as the THEOREM OF STURM, by which we may at onca
dtiermine the number of real roots of any Algebraic Equation, wi.h much more ease than by
previously discovered method.

In the present revised edition, one entire chapter on the subject of CONTINUED FRACTIONS
baer been added.

VI. ELEMENTS OF GEOMETRY, wiru PRACTICAL APPLICATIONS. $1.

The author has added throughout the entire Work, PRACTICAL APPLICATIONS, which, in the
esumation of Teachers, is an important consideration.

An eminent Professor of Mathematics, in speaking of this work, says: “ We have adopted
it, because it follows more closely the best molel of pure geometrical reasoning, which ever has
been, and perhaps ever will be exhibited ; and because the Author has condensed some of the
important principles of the great I.laster of Geometricians, and more especia.. has shown that
his theorems are not mere theory, by many practivul applications : a quality lu a text book o'
this science or less uncommon than it is important."
