POPULAR READINGS IN SCIENCE. By JOHN GALL, M.A., LL.B., late Professor of Mathematics and Physics, Canning College, Lucknow, and DAVID ROBERTSON, M.A., LL.B., B.Sc. With many Diagrams, a Glossary of Technical Terms, and an Index. Cr. 8vo, pp. 468. Price 5s. nett. The authors lay no claim to originality, but have exercised a judicious choice in the selection of subject-matter.... The narrative style which has been adopted by the authors will make the book acceptable to general readers who are anxious to make acquaintance with modern science.—_Nature._ It is hardly to be expected that this second volume of Constable’s _Oriental Miscellany_ will meet with such universal acclamation as the first volume, which consisted of Bernier’s _Travels_. But when rightly considered, it equally shows the thoroughness with which the publishers have thrown themselves into the enterprise.—_The Academy._ While the essays are such as would attract and instruct a general reader, they appear to have been written specially with a view to the needs of Indian students approaching the study of science for the first time.... They are well adapted to this end, and cannot fail to create in their readers a desire to push their knowledge further.—_The Scotsman._ The new volume of Constable’s _Oriental Miscellany_ would have delighted Macaulay and the champions of “Occidentalism” in Indian education in Lord William Bentinck’s day.... Messrs. Gall and Robertson ... have prepared a collection of essays which will be at least as acceptable to the general reader as to the student, in which the results of the most modern researches in physical science are brought up to date.... In each case the subject is treated in a clear and interesting way ... it is a most commendable undertaking.—_The Bombay Gazette._ The title sufficiently indicates the lines on which the two collaborators have worked. Theirs is no dry-as-dust text-book; it is rather a collection of scientific facts forming chapters in what has aptly been called the romance of science.... Messrs. Archibald Constable and Company have a particular interest in this country, and their _Oriental Miscellany_ is so well edited, printed, and published, that it is easy to predict for it a wide popularity.—_The Madras Mail._
