Total Eclipses of the Bun. By Mabel Loomis Todd. (Sampson

Low, Marston, and Co.)—This is the first volume of the " Colum- bian Knowledge Series," appearing under the editorship of Professor Todd. Mrs. Todd disclaims the idea of writing for astronomers. She has endeavoured to give "very unprofessional information to those without technical knowledge? However this may be, her book is certainly the book of a very well informed person, though it is written with a certain sparkle and liveliness of which the expert is seldom capable. A more convenient sum- mary of all that the outside student of astronomy can want to know could not be found.—We may mention a volume dealing with an interesting speciality, On Hail, by the Hon. Rollo Russell (Edward Stanford). Mr. Russell gives both facts and theories, putting together a great mass of information.
