LESSONS in ARITHMETIC for Junior Classes.

By JAMES TROTTER, of the Scottish Naval and Military Academy, &c.; Author of "A Key to Ingram's Mathematics," &c. A New Edition, revised. 18mo. 6d. sewed.

This little work was originally composed for the use of the Author's Junior Classes, and is now submitted to the public in the hope that will be found worthy of being introduced into Public Schools and Academies, and that, from the number and variety of the Exercises, it may prove a useful auxiliary to Governesses and Private Families.

"An excellent little compendium for teaching Arithmetic."-Asiatic Journal.

"It contains much fundamental information clearly expressed, a variety of useful tables, and some progressive and well-arranged exercises on the rules of Arithmetic up to the Rule of Three.”—Spectator.

HE PRINCIPLES of ARITHMETIC; and their Application to Business explained in a popular Manner, and clearly illustrated by simple Rules and numerous Examples. By ALEXANDER INGRAM, Author of "A Concise System of Mathematics," &c. 22d Edition. 18mo. Price only One Shilling bound.

"No other initiatory book with which we are acquainted possesses so many and such strong claims upon all who are employed in the business of education."-Edinburgh Weekly Journal.

"The arrangement is scientific,-the rules are perspicuous and simple, -the numerous exercises are well chosen to elucidate those rules, and to exemplify the arithmetic of actual life,-the results are remarkably accurate, and last, though not least, the price is so trifling as to place it within the reach of all classes of the community."-Edin. Evening Post.

"In this small volume there are more than eleven hundred examples, and many of these so judiciously chosen as to call forth the learner's thinking powers, and thus improve his mental faculties, as well as fit him for the active business of life.-It possesses all that an introductory work should have, and at the same time has nothing redundant.”—Dumfries Courier.

"This is a neat little volume, which contains much valuable matter, and promises to be exceedingly useful both in schools and for private students. The rules are laid down with great simplicity, and may therefore be easily comprehended."—Imperial Magazine.

MELROSE'S CONCISE SYSTEM of PRACTICAL

ARITHMETIC; containing the Fundamental Rules, and their Application to Mercantile Calculations; Vulgar and Decimal Fractions; Exchanges; Involution and Evolution; Progressions; Annuities, certain and contingent; Artificers' Measuring, &c. Revised, greatly enlarged, and adapted to Modern Practice. By ALEXANDER INGRAM and JAMES TROTTER. 19th Edition. 18mo. 1s. 6d. bound.

The Publishers again submit this work to public notice, not merely as an introduction, containing the most simple and useful Principles of Arithmetic, but as a complete treatise, comprehending every thing necessary for enabling the pupil to become master of this valuable science. The various Rules are so arranged as to reflect light on each other. Many new and easy methods of calculation are introduced, not to be found in any other work; and the unprecedented number and variety of questions subjoined to each section will afford a singular facility to the teacher in conducting his scholars, and to the pupils themselves in understanding and applying the rules.

Every attention has been paid to the accuracy and neatness of the work; and the Publishers confidently hope, that it will be found possessed of every quality requisite in a text-book.

HUTTON'S COMPLETE TREATISE on PRAC

TICAL ARITHMETIC and BOOK-KEEPING. Edited by ALEXANDER INGRAM. A New Edition, with many important Improvements and Additions; including New Sets of Books, both by Single and Double Entry, exemplifying the Modern Practice of Book-keeping. By JAMES TROTTER. 12mo. 3s. bound.

In preparing this Edition, various important objects have been steadily kept in view. Guided by his own experience, as well as by the suggestions of eminent Teachers, the Editor has made extensive alterations, which, it is hoped, will render the work more useful, and better suited to the present state of arithmetical instruction. Every exertion has also been made to present the most valuable matter in the simplest form; and while the Publishers are convinced that no other work of the kind is so complete in itself, combining as it does a full system of Practical Arithmetic and Book-keeping, and that at a lower price than is usually given for each separately, they confidently hope that it will meet with a corresponding degree of encouragement.

New Edition. 12mo. 2s. half-bound.

A work on Practical Book-keeping, composed on correct mercantile principles, embodying all the modern improvements, and sold at a moderate price, has been long wanted in our Schools and Academies. To supply this desideratum, and at the same time to meet the wishes of many intelligent Teachers, the Publishers have been induced to print by itself the Treatise contained in the new edition of Dr Hutton's Arithmetic and Book-keeping.

NGRAM'S CONCISE SYSTEM of MATHEMATICS, in Theory and Practice. With many Important Additions and Improvements. By JAMES TROTTER, of the Scottish Naval and Military Academy, &c. 5th Edition. In one thick volume 12mo, containing 520 pages, and illustrated by 340 wood-cuts. 7s. 6d. bound.

This work is unquestionably the cheapest Manual of Mathematics yet given to the public. Several of its sections are so complete in theory and minute in practical details, that if printed with a moderately-sized type and published separately, they would each cost more than the whole price at which the volume is now offered. The completeness of the work, indeed, will at once appear from the subjoined

"This is one of the most comprehensive works extant. As a general text-book, it is superior to most works, and much more portable and cheap than any we could name."-Westminster Review.

"It is certainly one of the most comprehensive manuals which have ever been drawn up either for schools or private students; none of the latter of whom, we apprehend, although even left without a master, will find any thing wanting in it which the title authorizes him to expect. We have, indeed, met with no other work of the kind which is at the same time so complete, various, and accurate, on the one hand,—and so cheap and in every way commodious, on the other."-Athenæum.

"This is perhaps, taking every thing into the account, the best book of its kind and extent in our language-at least we are not acquainted with a better. It contains every thing essential for the student of Elementary Mathematics, expressed most luminously, and with that proper medium of exposition equally removed from verbose amplification and obscure brevity. The arrangement too of the subjects merits praise, and the tables annexed to the end are beautifully, and, as far as we have been able to examine them, correctly printed. It is high but hardly exaggerated praise, to say of this little manual, that it comprehends nearly as much mathematics-that is, as many useful mathematical facts-as the three-volume course of Dr Hutton. It has our entire approbation."— New Monthly Magazine.

"We consider this book to be, in point of practical utility, unrivalled. and earnestly recommend it to the notice of our numerous readers, as the fittest work we have seen for being put into the hands of students in Mensuration."-Mechanics' Magazine.

"We have carefully examined this valuable work, and find it throughout excellently calculated for the purposes stated in the title. The matter is well selected and judiciously arranged; the practical rules are given with great clearness, and the illustrations prove the thorough knowledge of the late excellent author in all the practical details of this important branch of education. It is neatly and correctly printed, and, what we consider of importance in a work of this description, is remarkably cheap."-Edinburgh New Philosophical Journal.
