HARVARD COLLEGE LIBRARY GIFT OF THE CONGREGATIONAL LIBRARY OF BOSTON DEC 11 1935 District of Connecticut, 85. ✪ BE IT REMEMBERED, That on the twenty-eighth day of September, in the forty fifth year of the Independence of the United States of America, Samuel Green, (L. 8.) of said District, hath deposited in this office the title of a Book, the right whereof he claims as proprietor, in the words following, to wit: "Daboll's Schoolmaster's Assistant, improved and enlarged. Being a plain prac cal system of Arithmetick. Adapted to the United States. By Nathan Daboll." In conformity to the Act of the Congress of the United States, entitled, "An Ac for the encouragement of learning, by securing the Copies of Maps, Charts, and Books, to the authors and proprietors of them, during the times therein mentioned." Yale College, Nov. 27, 1799. I HAVE read DABOLL'S SCHOOLMASTER'S ASSISTANT. The arrangement of the different branches of Arithmetic is judicious and perspicuous. The author has well explained Decimal Arithmetic, and has applied it in a plain and elegant manner in the solution of various questions, and especially to those relative to the Federal Computation of money. I think it will be a very useful book to Schoolmasters and their pupils. JOSIAH MEIGS, Professor of Mathematics and Natural Philosophy. [Now Surveyor-General of the United States.] I HAVE given some attention to the work above mentioned, and concur with Mr. Professor Meigs in his opinion of its merit. NOAH WEBSTER. New-Haven Dec. 12, 1799. Rhode-Island College, Nov. 30, 1799. I HAVE run through Mr. DABOLL'S SCHOOLmaster's ASSISTANT, and have formed of it a very favourable opinion. According to its original design, I think it well" calculated to furnish Schools in general with a methodical, easy, and comprehensive System of Practical Arithmetic." I therefore hope it may find a generous patronage, and have an extensive spread. ASA MESSER, Professor of the Learned Languages, and teacher of Mathematics. [Now President of that Institution.] Plainfield Academy, April 20, 1802 I make use of DABOLL'S SCHOOLMASTER'S ASSISTANT in teaching common Arithmetic, and think it the best calculated for that purpose of any which has fallen within my observation. JOHN ADAMS, Rector of Plainfield Academy. [Now Principal of Philips' Academy, Andover, Mass,] Billerica Academy, (Mass.) Dec. 10, 1807. HAVING examined Mr. DABOLL'S System of Arithmetic, I am pleased with the judgment displayed in his method, and the perspicuity of his explanations, and thinking it as easy and comprehensive a system as any with which I am acquainted, can cheerfully recommend it to the patronage of Instructers. SAMUEL WHITING, Teacher of Mathematics. From Mr. Kennedy, Teacher of Mathematics. I BECAME acquainted with DABOLL'S SCHOOL MASTER'S ASSISTANT, in the year 1802, and on examining it attentively, gave it my decisive preference to any other system extant, and immediately adopted it for the pupils under my charge; and since that time have used it exclusively in elementary tuition, to the great advantage and improvement of the student, as well as the ease and assistance of the preceptor. I also deem it equally well calculated for the benefit of individuals in private instruction; and think it my duty to give the labour and ingenuity of the author the tribute of my hearty approval and recommendation, ROGER KENNEDY New-York, March 20, 1811. |
