Boston, May 24, 1832. The subscribers, Instructers in the public schools in the city of Boston, avail themselves of the earliest opportunity to express their approbation of Part Sec ond, of the North American Arithmetic,, by Frederick Emerson. The oral and written exercises being arranged in corresponding chapters and sections, may be taught separately or connectedly: this they deem a very great excel lence. The principles are laid down in progressive order, and are illustrated by the inductive method. Fractional Arithmetic is skilfully explained-and will no longer puzzle the learner. The work is evidently written with great care and ability. The undersigned, therefore, confidently hope its merits will be as fully and freely appreciated by the enlightened friends of education, as were those of Part First. P. MACKINTOSH, Jr. CHARLES FOX, A. ANDREWS, [Conclusion of a letter to the Publishers. The NORTH AMERICAN ARITHMETIC is not a mere repetition of other publications on the subject. It is an original work;-eriginal in its plan,--original in its execution,-or nal in its arrangement and questions,-original in every thing, excepting use of the inductive method. I think the author has been peculiarly happy in the unity and system of his treatise,-in the arrangement of oral and written exercises in corresponding chapters,―and, especially, in his mode of treating fractions. I am acquainted with no school-book that I could with more confidence recommend to the notice of teachers, and others interested in the subject of elementary education. E. BAILEY. [Principal of the Young Ladies' High School, Boston.] New York, Oct. 6, 1832. I consider Emerson's North American Arithmetic--Part First and Part Second, with the Key,-as perfect a School-book as I have ever examined. None on this branch of instruction has so well and truly illustrated the subject. It is plain and easy, and the characteristics which distinguish it as a schoolbook, are these that should prevail in every introductory work offered for the use of youth. SAMUEL W. SETON.
