JOHN W. DAVIS,
Boston, 15 November, 1821. l'have made use of tho Aritlimetic and Tables, which you sometime since prepared, on the system of Pestalozzi; and have been much grat. ified with the improved edition of it, which you have shown me. I am satisfied. from experiment, that it is the most effectual and interesting modo of teaching the science of numbers with which I am acquaintech
Having been made acquainted with Mr. Colburn's treatise on Arithmetic, and having attended an examination of his scholars, who had been taught aecording to this system, I am well satisfied that it is the most easy, simple, and natural way of introducing young persons to the first principles in the science of numbers. The method here proposed is the fruit of much study and reflection. The author has had considerable experience as a teacher, added to a strong interest in the subject, and a thorough knowledge not only of this but of many of the higher branches of mathematics. This little work is therefore earnestly recommended to the notice of those who are employed in this branch of early instruction, with the belief that it only requires a fair trial in order to be fully approva ed and adopted.
