Uranography.

From Youpg's Elements of Astronomy. 12mo. Flexible covers. 42 pages. besides four star maps. By mail, 35 cents; for introduction, 30 cents.

This volume is an independent work, and not an abridgment of the author's General Astronomy. It is a text-book for advanced High Schools, Seminaries, and Brief Courses in colleges generally. It was prepared by one of the most distinguished astronomers of the world, a most popular lecturer, and most successful teacher. It had every presumption in its favor, and the event has more than justified expectations. Special attention has been paid to making all statements correct and accurate so far as they go.

In the text no mathematics higher than elementary algebra and geometry is introduced; in the foot-notes and in the Appendix an occasional trigonometric formula appears, for the benefit of the very considerable number of High school students who understand such expressions.

G.B. Merriman, formerly Prof. of Mathemutics and Astronomy,
Rutgers College, New Brunswick, N.J.:

"For a short course in elementary astronomy, it is by far the best book I have ever examined."

Warren Mann, State Normal School, Potsdam, N. Y.:

"Accuracy in use of terms is a marked feature. I consider it the best text-book on this subject."

H.N. Chute, High School, Ann Arbor, Mich.:

"It is just the book the scholars have been waiting for."
