The series of "Chambers's Wonder Books" (W. and R. Chambers,

3s. 6d. per vol.) is one that should find favour with a large class of readers. There are four volumes before us,— Volcanoes and Earthquakes, by E. J. Houston, Ph.D.; The Atmo- sphere, by the same ; Photography for Young People, by Tudor Jenks; Electricity for Young People, by the same. it will be seen that two classes of readers have been provided for,—first, those who contemplate Nature, or, to use a less fine phrase, who feel an interest in the description of its great forces, here excellently exemplified by the extraordinary activities of the volcano and the permanent conditions of the air ; and secondly, those who have an impulse to put their knowledge into some practical shape. In this line we have the explanation of electrical forces and instructions as to how they may be applied, and in the region of photography a similar combination of theory md practice. The series may be most warmly recommended.—On a smaller scale we have Science at Home, by T. Baron Russell (J. F. Shaw, 2s.), giving "Simple Experiments forYoung People."
