Daniel Bixby & Co. 1 vol. 12 mo_.

This volume is edited by Professor Horsford, of Harvard University. It
is an acute and profound work of science, worth all the common books
on the subject put together. The author considers his investigation,
as recorded in the present volume, the most important he ever made.
His theory is this: "The surface of the body is a membrane from which
evaporation goes uninterruptedly forward. In consequence of this
evaporation, all the fluids of the body acquire, in obedience to
atmospheric pressure, motion toward the evaporating surface. This is
obviously the chief cause of the passage of the nutritious fluids from
the blood-vessels, and of their diffusion through the body. We know
now what important functions the skin (and lungs) fulfill through
evaporation. It is a condition of nourishment, and the influence of a
moist or dry air upon the health of the body, or of mechanical
agitation by walking or running, which increases the perspiration, is
self-evident." It will be readily seen that this discovery has an
important bearing upon the preservation of health.

_The Wanderings and Fortunes of Some German Emigrants
By Frederick Gerstacker. Translated by David Black. New
York: D. Appleton & Co. 1 vol. 12mo._

We have often desired to see a book of this character, giving the
first views and impressions of foreigners coming to settle here, as
they made their way from the Atlantic to the West. The present volume
is curiously minute in detailing the course and incidents of the
journey, and apart from its interest as a narrative, contains not a
little matter which should attract the attention of the statesman. In
respect to the merit of composition or description the book hardly
rises above mediocrity.

_Caesar's Commentaries on the Gallic War. With English
Notes, a Lexicon, Indexes, &c. By Rev. J. A. Spencer,
A. M. New York: D. Appleton & Co. 1 vol. 12mo._

This is the best edition of Caesar we have ever seen, and to the young
student it is invaluable. Every assistance is given to the complete
comprehension of the Commentaries; and few can rise from the diligent
perusal of the volume without having understood and almost exhausted
one at least of the classics.
