Extract of a letter from Hon. John C. Spencer, Secretary of State, and one of the Regents of the University of the State of New York.

MESSRS. BENNETT, BACKUS, & HAWLEY:

ALBANY, June 26, 1841.

GENTLEMEN-The Committee of the Regents of the University, have selected "PERKINS' ARITHMETIC" to be purchased and used in the departments for the instruction of Common School teachers, established by the Regents, in several Academies of the State.

JOHN C. SPENCER.

From Hon. John A. Dix, one of the Regents of the University of the State of New York.

MESSRS. BENNETT, BACKUS, & HAWLEY:

ALBANY, June 8, 1841.

GENTLEMEN-I have examined Mr. George R. Perkins' Higher Arithmetic, and consider it a very valuable work, filling as it does, a space which is usually but a portion of more voluminous treatises. For academies and high schools, and for the purpose of exercise and discipline to those who have become familiar with the common rules of arithmetic, it is appropriate and useful, both on account of the manner in which the various subjects are treated, and the clearness of its illustrations. JOHN A. DIX.

From I. W. Jackson, A. M., Professor of Mathematics, Union College. SCHENECTADY, June 4, 1841.

MESSRS. BENNETT, BACKUS, & HAWLEY:

GENTLEMEN-I have examined the treatise on the Higher Arithmetic, by Prof. Perkins, which you were so good as to send me, and am most happy to give you my opinion of its merits.
