RECOMMENDATIONS.

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, December 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.
