shall be no more. But how industry is to be then organised he only hints ; 



how its products are to be distributed, and what form society is to take, he 



leaves in darkness. His business is not with the future ; it is with the past and 



the immediate present.

The Indian Museum, 1814-1914. [Pp. 154 + lxxxvii, with 11 illustrations.] 

 (Calcutta : Published by the Trustees of the Indian Museum.) 



This volume has been published in commemoration of the centenary of the 

 foundation of the Museum of the Asiatic Society of Bengal, which was brought 

 under Government control in 1866, and thus became the Imperial Museum of 

 India as it now exists. The Indian Museum is, however, scarcely a single 

 institution, but rather a federation of institutions. The trustees and the 

 superintendent directly control only the zoological and anthropological section, 

 and they have but slight powers over the geological, archaeological, artistic, and 

 industrial sections, which are administered by other bodies. This anomalous 

 arrangement is said to work well, but whether it can be permanent seems doubtful. 

 The Museum is not a mere place of preservation for specimens representing the 

 natural history and culture of India, but is an educational centre for Calcutta, and 

 hence foreign objects, such as marsupials, are exhibited, and there are about 

 800,000 visitors a year. The staff also undertake original investigations, and 

 zoologists the world over are familiar with the Museum's publications. The 

 different chapters (which are written by different authors) describe fully the 

 history of the institution and of its separate sections, and there are several 

 appendices giving the Museum Acts, statistics, and so forth ; but we think the 

 book would have gained in interest if the account of the actual contents of the 

 Museum had been less meagre. It is no reflection on the small staff of the Museum 

 to say that the anthropological department is at present very unequal to the great 

 opportunities of the Government of India.

Handbook of Photomicrography. By H. Lloyd Hind, B.Sc, F.T.C, and 

 BROUGH RANDLES, B.Sc. [Pp. x + 292, with 44 Plates and 71 Text- 

 Illustrations.] (London : George Routledge & Sons. Price ys. 6d. net.) 



This book is said to be " the outcome of a series of articles originally published 

 in the Photographic Monthly, and intended as an introduction to photomicro- 

 graphy from a photographer's point of view." In it the subject has been 

 approached from its two aspects, with descriptions of both — photographic and 

 microscopic technique ; and " it is hoped that experts in either field will look with 

 indulgence on an elementary treatment of the subjects with which they are 

 familiar. At the same time, however, the processes are discussed in sufficient 

 detail to be of use in research, for which the full possibilities of the combination 

 of microscopy and photography are scarcely yet realised." The authors have 

 well justified their design, and the book will prove very useful even to such 

 " experts " as they refer to. The chapters deal with Photomicrographic Apparatus, 

 the Microscope, Lamps and Illuminants, Low-Power Photomicrography, Critical 

 Photomicrography, Colour Screens and Colour Sensitive Plates, Exposure, 

 Oblique and Dark-ground Illumination, Opaque Objects, Metallography, Colour 

 Photomicrography, Photographic Operations, and Some Applications of Photo- 

 micrography. There are numerous good plates and an Appendix and Formulas. 

 The work will be almost a necessity in most laboratories.
