THE NORTH AMERICAN ARITHMETIC. PART THIRD, FOR ADVANCED SCHOLARS. BY FREDERICK EMERSON, BOYLSTON SCHOOL, BOSTON, Entered according to act of Congress, in the year 1834, by Frederick Emerson, in the Clerk's Office of the District Court of the District of Massachusetts. RECOMMENDATIONS. CAMBRIDGE, Oct. 31, 1834, To the Publishers of Emerson's Arithmetic.-Gentlemen - I have exam. ined the Third Part of Mr. Emerson's Arithmetic, with great pleasure. The perspicuity of its arrangement, and the clearness and brevily of its explanations, combined with its happy adaptation to the purposes of practical business are its great recommendations. I hope it will soon be introduced into all our schools, and take place of the in-digested Treatises, to which our instructers have hitherto been compelled to resort. Respectfully, BENJAMIN PEIRCE, (Professor of Mothematics and Nat. Philo. Harvard Universityu Boston, Nov. 10, 1834. To the Publishers of Emerson's Arithmetic.-1 have carefully examined the Third Part of the North American Arithmetic, by Mr. Emerson; and am so well satisfied that it is the best treatise upon the subject, with which I am acquainted, that I have determined to introduce it as a text-book into my school. Very respectfully, &c., yours, E. BAILEY, [Principal of the Young Ladies' High School, Boston.) From the Boston Public Schoolmasters. Boston, Nov. 16, 1834. We have considered it our duty to render ourselves acquainted with the more prominent systems of Arithmetic, published for the use of schools, and to fix on some work which appears to unite the greatest advantages, and report the same to the School Committee of Boston, for adoption in the Public Schools. After the most careful examination, we have, without any hesi. tancy, come to the conclusion, that Emerson's North American Arithmetic (First, Second, and Third Parts) is the work best suited to the wants of all classes of scholars, and most convenient for the purposes of instruction. Accordingly, we have petitioned for the adoption of this work in the Public Schools. P. MACKINTOSH, JR. Levị CONANT. JOHN P. LATHROP. Orders of the Boston School Committee... At a Meeting of the School Comnzittee, Nov. 18,1834, Ordered, That Emersop's North American Arithmetic Second and Third Parts, be substituted in the Writing Schools, for Colburn's First Les. sons and Sequel.* Ordered, "That the Arithmetics now in use be permitted to their present owners; hut that whenever a scholarshall have occasign, to purchase a new one, the North American Arithmetic shall be required. Attest, S. F. M'CLEARY, Secretary. * The FIRST PART was already adopted, by a previous order. PREFACE. The work now presented, is the last of a series of books, ander the general title of The North AMERICAN ArithMetic, and severally denominated Part First, Part Second, and Part Third. Part First is a small book, designed for the use of childreu between five and eight years of age, and suited to the convenience of clas3-teaching in primary schools. Part SECOND consists of a course of oral and written exercises united, embracing sufficient theory and practice of arithmetic for all the purposes of common business. Part THIRD comprises a brief view of the elementary principles of arithmetic, and a full development of its higher operations. Although it is especially prepared to succeed the use of Part Second, it may be conveniently taken up by scholars, whose acquirements in arithmetic are considerably less than the exercises in Part Second are calculated to al ford. While preparing this book, I have kept in prominent view, two classes of scholars; viz.— those who are to prosecute a full course of mathematical studies, and those who are to embark in commerce. In attempting to place arithmetic, as a science, before the scholar in that light, which shall prepare him for the proper requirements of college, I nave found it convenient to draw a large portion of the examples for illustration and practice, from mercantile transactions; and thus pure and mercantile arithmetic are united. No attention has been spared, to render the mercantile information here presented, correct and adequate. Being convinced, that many of the statements relative to commerce, which appear in books of arithmetic, have been transmitted down from ancient publications, and are now erroneous, I have drawn new data from the counting-room, the insurance office, the custom-house, and the laws of the present times. The article on Foreign Exchange is comparatively extensive, and I hope it will be found to justify the confidence of merchants. Its statements correspond to those of the British • Universal Cambist,' conformably with our value of foreign coins, an fixed by Act of Congress, in 1834, 1400** |
