HAR^DWICKE'S SCIENCE-GOSSIP.

mollusca, and other marine animals were made, and 

 we find remarks on them in the appendix by the 

 scientific authorities in whose hands they were placed 

 for examination. 



Fossil Sponge Spiailcs from the Upper Chalk, by- 

 George Jennings Hinde, F.G.S. (Munich), is a short 

 Monograph on the results of a careful examination of 

 a few ounces of chalk found inside one of the flint 

 Paramoiuiras or "Pot-stones" of Norfolk. It is 

 illustrated by fine plates, each crowded with details 

 of sponge spiculse, and the work is a good proof to 

 the student of what can be done by careful observa- 

 tion, and how the most unpromising ground may be 

 made to yield both something interesting and some- 

 thing new. This book cannot fail to still further 

 increase the reputation which Mr. Hinde has already 

 gained as a careful and diligent geologist. 



A Mojiograph of the Silurian Fossils of the Girvan 

 District, by Professor H. A. Nicolson and Robert 

 Etheridge, jun., F.G.S. (London and Edinburgh : 

 W. Blackwood & Sons). We are glad to welcome 

 this, the third fasciculus of the work, dealing with 

 the fossil annelida and echinodermata, corals, &c., 

 of the richly fossiliferous Silurian district of Girvan, 

 in Ayrshire. When completed this work will be a 

 most important one to the geologist, for the numerous 

 plates are exquisitely e.xecuted. 



A Smaller Manual of Modern Geography, Physical 

 and Political, by John Kichardson, M.A. (London : 

 John Murray). A capital school manual, carelully 

 prepared, the geography of all that relates to the 

 British Empire being treated with the especial fulness 

 and clearness which the subject demands. 



Natural Philosophy, by Ganot, translated and 

 edited by Professor E. Atkinson, F.C.S. (London : 

 Longmans & Co.). We have received a fourth 

 edition of the above excellent work for students, 

 which, as many of our readers may be aware, is an 

 adaptation and abridgment of Ganot's Elements de 

 Physique in a more elementary and popular form. 

 About twenty-five pages of new matter and sixteen 

 additional illustrations will be found in this, the 

 latest addition. 



A Simple Treatise on Heat, by W. Matthieu 

 Williams, F.R.A. S., &c. (London: Chatto & Windus). 

 We confidently recommend this well got up little 

 book as the best elementary modern treatise on the 

 science of heat we have yet seen. No previous 

 knowledge of a very complex science is required to 

 master the general details and laws. It is just the 

 very book for science classes. 



Steam, and the Steam Engine, by Henry Evers, 

 LL.D. (London, Glasgow, and Edinburgh : W. 

 Collins). This work is a new and revised edition of one 

 of " Collins's Advanced Science Series ; " and as we 

 see by the title-page it is numbered "twenty-sixth 

 thousand," we must accept it as a successful and much 

 required book. It deals with all kinds of steam 

 engines, land, marine, and locomotive, and this new 



edition has been thoroughly revised and brought up 

 to date, and a new chapter added on " Compound 

 Engine:-." 



Organic Chemistry, by Dr. W. B. Kemshead 

 (London, &c. : W. Collins), is one of the new and 

 revised editions of "Collins's Elementary Science 

 Series," capitally adapted for the use of students 

 preparing for the South Kensington and other, ele- 

 mentary examinations. 



Conscious flatter, by W. Stewart Duncan (Lon- 

 don : David Bogue), is intended to repel certain 

 objections against the progress of modern psychology. 

 The author regards Nature as a living whole, con- 

 scious as well as active. It is a very thoughtful, 

 well-written little book, well worthy of careful study. 



Unconscious Memory, by Samuel Butler, author 

 of "Erewhon," &c. (London: David Bogue). We 

 are sorry, for the sake of Mr. Butler's reputation, 

 that he has written this book, and still more so that 

 he thinks it necessary to suspect Dr. Darwin of 

 having treated him unfairly. On reading it we 

 are only still further confirmed in the impression 

 received from the perusal of Mr. Butler's previous 

 book — that he has not had - the requisite scientific 

 training to enable him to get the necessary mental 

 grasp of modern biological theories. Whatever Mr. 

 Butler writes is sure to be well and attractively 

 written, and this book is no exception to the rule. 



Perttz'ian Bark, by Clements R. Markham, C.B. 

 (London : John Murray). We have here a popular 

 account of the introduction of chinchona cultivation 

 in British India, i860 to 1880. The title-page, how- 

 ever, gives no idea of the lively narrative of the travels 

 and adventures of Mr. Markham and his assistants, 

 which this book records. It was a brave, patriotic, 

 and humane work, and Mr. Markham very modestly 

 but very feelingly and interestingly relates the 

 story of the successful plantation of chinchona trees 

 in India. Some of the chapters give picturesque 

 zoological, botanical, and physical descriptions of the 

 regions of the Andes. This is emphatically a good 

 and highly readable book. 



The Guests of Flotuers, by C. E. Meetkerke. 

 (London : Griffith & Farran). This charmingly 

 got up brochure is intended as a botanical sketch for 

 children, very clearly and ably setting forth the 

 relations between insects and flowers. It will form 

 an admirable gift-book for young folks. 



Plant-Life (London : Marshall Japp & Co.) is an 

 unpretending book whose contents cover a very 

 great extent of botanical ground, particularly those 

 parts which are new and interesting. Thus we have 

 chapters on microscopic plants, fertilisation, predatory 

 plants, remarkable flowers and leaves, folkdore, 

 mosses, &c., all abundantly and well illustrated, 

 proving the author to be a man of thorough 

 botanical culture, and possessing much grace of 

 literary style. A few errors require correction, such 

 as figuring a fuschia with ten stamens.
