A Voyage in Space. By H. H. Turner, D.Sc., F.R.S.

(S.P.C.K. 6s. net.)—The Savilian Professor at Oxford delivered these lectures to children at the Royal Institute in the Christmas holidays two years ago. In book-form they will be a delightful introduction to the wonders of the universe. In a lecture-room where the experiments could be seen they must have fascinated the audience, especially as they were evidently delivered with plenty of discursive humour to keep the lively attention of the young listeners. The whole solar system and the vaster regions of space beyond are reviewed, and explanations given to show how knowledge of them has been reached by reason or by the technical devices of telescopes, old and new, or other scientific instruments and experiments. The book is liberally illustrated.
