CURRENT LITERATURE.

Advanced Physiography. By J. Thornton. (Longmans and Co.) —It would be equally correct to call this an elementary astronomy,. for the greater part is devoted to the study of the movements of the sun, the planets, the moon, the stars, and the comets. At the end, indeed, we are told a little more about the atmosphere and oceanic movements. The whole book might very well have been devoted to the earth; there is plenty to tell the student about it before leaving its surface. Still, the student will learn a great deal from the chapters on spectrum analysis, astronomical instru- ments, and astronomical measurements. The book is plentifully illustrated.
