Works by the late Dr. James R. Nichols.

WHENCE? WHAT? WHERE? A VIEW OF THE ORIGIN, NATURE, AND DESTINY OF MAN. By James R. Nichols. With portrait of the author. 12mo. Cloth, gilt top. $1.25. Eleventh edition, revised.

No one can take up the book without feeling the inclination to read further, and to ponder on the all-important subjects which it presents. Though it is not a religious book in the accepted sense of the word, it is a book which calls for the exercise of the religious nature, and which in diffusing many sensible ideas will do good.”—Philadelphia Press.

FIRESIDE SCIENCE: Popular Scientific Essays. 12mo. Cloth. $1.50.

These essays have been an endless source of instruction and interest to all that have read them, while, to those who approach the mysteries of Nature with an inquiring and reverent spirit, they will be of great assistance in aiding the comprehension of the technical works on chemistry and physics. Since Faraday delivered his well-known lectures, there has been nothing to compare with the present work in tracing the action of the immutable laws of Nature in processes of every-day occurrence.

CHEMISTRY OF THE FARM AND THE SEA, with many other familiar Chemical Essays. 16mo. Cloth. $1.25.

This work, though perhaps not of so wide an interest to the average reader, is of the greatest value to the thoughtful and practical farmer. Not the least of Dr. Nichols’ talents was his deep insight into and wonderful grasp of agricultural chemistry, and many men to-day can bear witness to the value of his advice respecting soils and fertilizers. In this volume will be found the gist of a series of lectures and addresses delivered before the various agricultural communities of New England and elsewhere, which abound with helpful suggestions and solid facts.
