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. [Since 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.


I HAVE run through Mr. DABOLL'S SCHOOLMASTER'S ASSISTANT, and have formed of it a very favorable 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 Arith metic." 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. [President of that Institution.]
