RECOMMENDATIONS.

YALE-COLLEGE, Nov. 27, 1799. I ILAVE read DABOLL'S SCHOOLMASTER's Assistant. Thearrangement 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.

RHODE-ISLAND COLLEGE, Nov. 30, 1799. I HAVE run through Mr. Daboll's ŠCHOOLMASTER'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 method. ical, easy and comprehensive System of Practical Arith, metic." "I therefore hope it may find a generous patronage, and have an extensive spread.
