A Philosophical and Practical Treatise on the Will. 12mo, Sheep extra. $1 25.

This work is one of great value to the literary and religious community. It indicates throughout not only deep and varied research, but profound and laborious thought, and is a full, lucid, and able discussion of an involved and embarrassing subject. The style, though generally diffuse, is always perspicuous, and often elegant; and the work, as a whole, will add much to the reputation of its author, and entitle him to rank among the ablest metaphysicians of our country.—Christian Advocate.

An invaluable treatise for the agriculturist, whose suggestions and information would probably save him ten times its cost every year of his labor.—Evangelist.

In the Farmer's Dictionary we find what has never before been drawn up for the farmer: no where else is so much important information on subjects of interest to the practical agriculturist to be found.—Cultivator.

Buel's Farmer's Companion;

Or, Essays on the Principles and Practice of American Husbandry. With the Address prepared to be delivered before the Agricultural and Horticultural Societies of New Haven County, Connecticut. And an Appendix, containing Tables, and other Matter useful to the Farmer. To which is prefixed a Eulogy on the Life and Character of Judge Buel, by Amos Dean, Esq. 12mo, Muslin. 75 cents.

"This is decidedly one of the best elementary treatises on agriculture that has ever been written. It contains a lucid description of every branch of the subject, and is in itself a complete manual of Husbandry, which no farmer, who would understand his own interest, should be without. It is sufficient to say that this is the last production of the late Judge Buel, and contains his matured experience and opinions on a subject which he did more, perhaps, to elevate and promote than any other man of his time. Judge Buel was a strong advocate for what is termed the New Husbandry, the many advantages of which over the old system he illustrated by his own practice, and the claims of which to the consideration of the farmer are ably set forth in this volume. The work is written with great perspicuity, and the manner in which the subject is treated shows the hand of a master. The clearness and simplicity of the style adapt it to all classes of readers; and containing as it does a copious Index, Glossary, &c., it is eminently suited as a text-book for country schools, into which we hope it will be speedily introduced, and its principles thoroughly studied and practically carried out. It is also a very suitable book to be given as a premium, and we therefore recommend it to the notice of our Agricultural Societies."

A NEW Classified and Descriptive Catalogue of Harper & Brothers' Publications has just been issued, comprising a very extensive range of Literature, in its several Departments of History, Biography, Philosophy, Travel, Science and Art, the Classics, Fiction, &c.; also, many splendidly Embellished Productions. The selection of works includes not only a large proportion of the most esteemed Literary Productions of our times, but also, in the majority of instances, the best existing authorities on given subjects. This new Catalogue has been constructed with a view to the especial use of persons forming or enriching their Literary Collections, as well as to aid Principals of District Schools and Seminaries of Learning, who may not possess any reliable means of forming a true estimate of any production; to all such it commends itself by its explanatory and critical notices. The valuable collection described in this Catalogue, consisting of about two thousand volumes, combines the two-fold advantages of great economy in price with neatness—often elegance of typographical execution, in many instances the rates of publication being scarcely one fifth of those of similar issues in Europe.
