THE HEAVENS: an Illustrated Hand-

book of Popular Astronomy. By AMEDEE CUILLEMIN. Edited by J. NORMAN LOCKYER, PRS. F.R.A.S.

“Tf anything cats make the study of astronomy easy and engaging to ordinary minds, it will assuredly be a work of the attractive style and hand- some—we may almost say sumptuaus—aspect of M. Guillemin's treatise on ‘The Heavens," It deserves to be spoken of with all praise, as one towards which author, editor, illustrator, and publisher have cqually done their best. Of the translation itself we cannot speak too highly. It has all the force and freshness of original writing.”—Sa/urday Neotew,
