It is interesting t o recall in this connection that the first resolution of an inorganic complex salt was carried out by an American student working in Werner's laboratory. Cornell's department of chemistry is t o he congratulated on its choice of a kcturer and t o he thanked for sharing the benefits of its Baker Lectureship with other chemists. Professor Jaeger could not have left a more valuable souvenir of his visit to this country. LAWRENCEW. BASS

he is interested in.
The fifth chapter covers the theorems of Taylor and MacLaurin regarding series. Fourier series are mentioned. A necessarily hrief discussion of differential equations is presented in the sixth chapter. The addition of a chapter (Chapter 8) on the theory of errors is of course quite in order in a hook meant t o he used by experimental scientists. The treatment seems adequate for an introduction t o the subject. Again i t is felt that this interesting volume can be made even more useful by the inclusion of many more problems.
