RECOMMENDATIONS.

From B. A. GOULD, Principal of the Public Latin School, Boston

Boston, 22d Oct., 18:22 DEAR SIR,

I have been highly gratified by the examination of the second part of your Arithmetic. The principles of the science are unfolded, and its practical uses explained with great perspicuity and simplicity I think your reasonings and illustrations are peculiariy happy and original. This, together with your “ First Lessons,” forms the most lucid and intelligible, as well as the inost scientific systern of Arith. metic I have ever seen. Its own merits place it beyond the need of commendation.

With much esteem,
Sir, your obedient servant,

B. A. GOULD
Mr. WARREN COLBURN.

Boston, 22d Oct., 1822. DEAR SIR,

I lave carefully examined a large portion of your manuscript, and do not hesitate to recommend it very highly to every person who wishes to teach arithmetic in:elligibly. The arrangement is very much better, the explanations more convincing, and the rules, from the mode in which they are introduced, are clea, er and simpler, thun can be found in any book on the sutject with which I am ncquainted I am, with great respect,

Yours, &c.

G. B. EMERSON. Mr WARREN COLBURN.
