"This is a neat volume and a useful one. Such a book has long been wanted in America. It should receive a wide-spread patronage."—Scientific American, New York.

"It meets a want long felt, both among men of science and the people. No one who feels any interest in the intellectual progress of the age, no mechanic or artisan, who aspires to excel in his vocation, can afford to be without it. A very copious and accurate index gives one all needed aid in his inquiries."—Phil. Christian Chronicle.

"One of the most useful books of the day. Every page of it contains some useful in formation, and there will be no waste of time in its study."—Norfolk Democrat.

"It is precisely such a work as will be hailed with pleasure by the multitude of intelligent readers who desire to have, at the close of each year, a properly digested record of its progress in useful knowledge. The project of the editors is an excellent one, and de serves and will command success."—North American, Philadelphia.

"Truly a most valuable volume."—Charleston (S.C.) Courier.

"There are few works of the season whose appearance we have noticed with more sincere satisfaction than this admirable manual. The exceeding interest of the subjects to which it is devoted, as well as the remarkably thorough, patient and judicious manner in which they are handled by its skilful editors, entitle it to a warm reception by all the friends of solid and useful learning."—New York Tribune.
