Ten new volumes of "The Cambridge Manuals of Science and
Literature " (Cambridge University Press, ls. net each) have just been published. The literary side of the series is represented only by a single volume, Mysticism in English Literature, by Miss C. F. E. Spurgeon, though the kindred subjects of philosophy and history are also dealt with in .English Monasteries, by Mr. A. H. Thompson, and Plato; Moral and Political Ideals, by Mrs. A. M. Adam. Two volumes deal with economics, namely, The Theory of Money, by Mr. D. A. Barker, and Co-partnership in Industry, by Mr. C. R. Fay. Mr. 0. H. Latter contributes an interesting monograph upon Bees and Wasps, while the fascinating question of the distribu- tion of animals and its causes is discussed by Mr. Hans Gadow in The Wanderings of Animals. Zoology, botany, geology, and anthropology are all touched upon in Mr. Clement Reid's .volume upon Submerged Forests. Mr. C. L. Fortescue writes upon Wireless Telegraphy, while, finally, the most abstract problems of physics are dealt with by Mr. John Cox in Beyond the Atom. This last volume is certainly the most obscure of the ten before us ; but even it is not beyond the grasp of an attentive layman, especially if he has some slight knowledge of mathematics. In general it may be said that the authors continue to strike a successful line between extreme specialization and extreme popularity of treatment.
