Star - Land. By Sir Hobert S. Ball. (Cassell and Co.)—Two courses

of lectures which Sir R. Ball delivered in 1881 and 1887 to young people at the Royal Institution are here published, with illustrations, in the form of an introduction to the study of astronomy. The style and general tenor of the book are in

accordance with the sub-title, "Talks with Young People," and are sure to prove attractive even to older folk. Science lectures aro always more acceptable to young folk when thrown into a conver- sational form, and this the writer has endeavoured to maintain, as far as the exigencies of print would allow him.
