.Physics in. Pictures, with Explanatory Text, prepared by Theodore Eckhardt

and translated by A. H. Keane (Stanford), belongs to "Stanford's Series of Instructive Picture-books." The "principal natural phenomena and appliances " are pictorially repreiented. The scope of the work is almost too large. " A Locomotive," "A Section of a Fall-rigged Screw Corvette," "A Morse Writing Telegraph," "A Microscope," " A Spectroscope," are among the subjects of the thirty coloured plates. Then, again, in quite another direction we get "A Watch," "A Water-wheel ;" and, again, in a third, "An Aurora Borealis." But the usefulness of the book is beyond all question.
