THE rzormies Boors.—The fifth dozen volumes of the" People's Books"

(T. C. and E. C. Jack, 6d. net each) have now been published, and they deal with a wide variety of topics. Taking first, for instance, the four biographical volumeS, we find such different studies as Cecil John Rhodes, by Ian D. Colvin ; Words- worth, by Rosanne Masson ; Friedrich Nietzsche, by M. A. Mftgge; and Welliugton and Waterloo, by Major 0. W. Redway. Not the least interesting of the other books is that by Mr. Philip Jonrdain upon The Nature of Mathematics. Mr. Jourdain has a discursive mind, that is to say that he leans towards the philosophical rather than the purely mathematical view of his subject. If we add to this that he has considerable facility in exposition it will be enough to suggest that his pages, though rather tough food, are excellently suited for rumination. Mr. John Macdonald's Turkey and the Eastern Question is likely to prove attractive on account of its bearing upon current affairs ; and we may mention, finally, a handy Atlas of the World, containing more than fifty maps prepared by Mr. J. Bartholomew.-
