Reviews — SJierhorn's Forarninifera. 377 



The Tertiary strata of the Peninsula (Chap. XIIL), and of the 

 Himalaya (Chap. XIV.), have been carefully re-arranged, with new 

 information on some points. The great and extensive Nummulitic 

 Limestone (Eocene) comes into this part of the series (the reference 

 "Nummulites, cretaceous, in Baluchistan, 291," in the Index is a 

 mistake; no Nummulites are really present). The extraordinary 

 fossil Mammalian Fauna of the Sewalik strata, and their associated 

 land and fresh- water shells, appear in their place as belonging to the 

 Upper Tertiary in Chap. XIV. The Laterite, the Pleistocene, and 

 Eecent deposits, and the features and composition of the great 

 Indo-Gangetic plain, follow with some additional knowledge in 

 Chapters XV., XVI., and XVII. Chap. XVIII., on the Origin and 

 Age of the Himalayas, and Chap. XIX., on the Geological History 

 of peninsular India, are newly arranged and freshly written. 



Besides some 27 woodcuts, in the text (mostly new), there are 

 16 plates (not numbered) of fossils, " phototyped " from either some 

 re-arranged figures of the former plates, or specimens different from, 

 but more or less similar to, those figured in the previous plates, — 

 also a fine view, from a photograph, of the snow-capped Simvo 

 (22,300 feet high) in the Himalaya,— a map of the Hill-ranges of 

 India, modified from the former map, — a map and plans of the 

 Volcanoes of Burma and Bay of Bengal,— a map of the Indo- 

 Gangetic Alluvium,— a plate of sections of the Himalayas and Sub- 

 Himalayas ; also a good map of the Himalayas,— and a new geolo- 

 logical map of India, dated 1891. Moreover, a useful " Geographical 

 Index of Indian localities " fills 30 pages. 



This book cannot but prove useful to those who wish to enquire 

 into the structure and physical history of India and adjoining terri- 

 tories. Some notion of the characteristic fossils can be got from 

 the figures ; but they are far inferior to the plates in the first edition ; 

 and so indeed is the printing and general finish of the volume. 

 The Index is faulty ; many points are poorly treated ; for instance, 

 Baluchistan does not take a place in the alphabet, but appears 

 incidentally, once with a wrong page, and once with a palseon- 

 tological mistake (noticed above) ; and Nagpur is omitted altogether, 

 though an important centre of geological facts both physically and 

 historically. 



When the next edition is required (it may be soon, with advantage), 

 better paper and type, a more exact style of printing scientific and 

 technical words, some improvement in other editorial points, and a 

 more considerate title-page will make it compare more favourably 

 with the first edition, and greatly enhance its value. T. E. J.

AMONG the many minute organisms in the sea are those which 

 influence the features of the sea-bottom, by either local or 

 widespread accumulation of what we may call shell-matter. Some- 

 times this occurs to such an extent as to modify the fairway of ships ;
