5. An Introduction to the Geology of Dayton ( Ohio) and 

 vicinity, with special reference to the Gravel Ridge Area south 

 of the City, including Hills and Dales and Moraine Park y by 

 Aug. F. Foerste. Pp. 210, with many illustrations and maps. 

 Dayton, 1915. — This well prepared and beautifully illustrated 

 book was written by the author to simulate interest in nature 

 studies and especially in the surficial and glacial geology in the 

 vicinity of Dayton, Ohio. It is a labor of love, made possible 

 through the kindness of Mr. E. A. Deeds. Attention is called to 

 it here in the hope that others may read it and be stimulated to 

 prepare something of the same sort for other large communities.

6. Studies in Edrioasteroidea, I-JJC: by F. A. Bather. 

 Pp. 136, 13 pis., 191. — Doctor Bather of the British Museum of 

 Natural History brings together in this very valuable work nine 

 studies which he has published since 1898. They relate, on the 

 one hand, to the detailed structure of Dinocystis, Edrioaster, 

 Lebetodiscus, Steganoblastus and Purgocystis, and, on the other, 

 to the morphology and bionomics of the Edrioasteroidea and 

 their genetic relations to other echinoderms, and more particularly 

 the starfishes. To these reprints he adds a few corrections, a 

 preface, and an index : the whole may be had of the author for 

 ten shillings. The work should be in the library of all who are 

 interested in the Echinodermata. c. s. 



7. Handbuch der Regionalen Geologic — This great under- 

 taking — the geology of the world — begun in 1910, has now 

 appeared in eighteen numbers. It was intended to complete the 

 series in a few years, but evidently it will be many years more 

 before the work is finally ended. So far the regions described 

 are: (l) Denmark (by Ussing), (2) Iceland (Pjeturss), (3) Phil- 

 ippines (W. D. Smith), (4) Middle Atlantic volcanic islands 

 (Gagel), (5) New Zealand (Marshall), (6) Madagascar (Lemoine), 

 (7) Spain (Douville), (8) Persia (Stahl), (9) Oceania (Marshall), 

 (10) Armenia (Oswald), (11) United States (Blackwelder), (12) 

 Netherlands (Mohlengraaff), (13) Norway, Sweden and Finland 

 (Hogbom), (14) West Africa (Lemoine-Parkinson), (15) Antarc- 

 tica (Nordenskjold), (16) Balkans of Austria-Hungary (Schu- 

 bert), (17) Syria, Arabia and Mesopotamia (Planckenkorn).

 Estudantes Brazileiros e d Geologia do Brazil • by John C. 

 Brajstner. Second edition, 1915, pp. 396, 174 text figs. — Pro- 

 fessor Branner has long been deeply interested in the geology of 

 Brazil, aud he here presents a second edition of his text-book in 

 Portuguese of Elementary Geology, with special reference to 

 Brazil. Dynamical Geology occupies about 200 pages, Structural 

 Geology 70 pages, and Historical Geology 100 pages. There are 

 plates of Silurian, Devonian, Pennsylvanian, Permian, Jurassic, 

 Cretaceous and Tertiary fossils native to Brazil. c. s.
