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 Computa tion of money. I think it will be a very useful book to Schoolmasters and their pupils.

I HAVE given some attention to the work above men-
tioned, and concur with Mr. Professor Meigs in his opin
ion of its merit.

I HAVE run through Mr. DABOLL'S SCHOOLMASTER'S

ASSISTANT, and have formed of it a very favourable opin、 I ion. According to its original design, I think it well "calculated to furnish Schools in general with a methodi cal, easy, and comprehensive System of Practical Arithmetic." I therefore hope it may find a generous patronage, and have an extensive spread.
