CHARLES A. INGERSOLL.
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 ex. plained Decimal Arithmetic, and has applied it in a plain and elegant inanner 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 men. tioned, and concur with Mr. Professor Meigs in his opin. · ion of its wierit.
Rhode-Island College, Nov. 30, 1799 HAVE run through Mr. DABOLL'S SCHOOLMASTER'S ASSISTANT, and have formed of it a very favourabic opin ion. According to its original design, I think it well 6 calculated to furnish Schools in general with a methodie cal, easy, and comprehensive System of Practical Arithmctic." I therefore hope it may find a generous patronage, and have an extensive spread.
