manual has long been felt, and this work makes its appearance 

 under the advantage that it seeks to occupy a place which has long 

 been -vacant. No effort has been spared to make the work worthy 

 of confidence, and, by the publication of an occasional supplement, 

 it is hoped to maintain it for many years as the ' ' Handbook 

 for every student of British Fungi. Appended is a coviplete alpha- 

 betical Index of all the divisions and subdivisions of the Fungi 

 noticed in the text. The book co7itains ^oo figures. " Will main- 

 tain its place as the standard English book, on the subject of which 

 it treats, for many years to come." — Standard. 



Dawson (J. W.)— ACADIAN GEOLOGY. The Geologic 

 Structure, Organic Remains, and Mineral Resources of Nova 

 Scotia, New Brunswick, and Prince Edward Island. By John 

 William Dawson, M.A., LL.D., F.R.S., F.G.S., Principal and 

 Vice- Chancellor of M'Gill College and University, Montreal, &c. 

 Second Edition, revised and enlarged. With a Geological Map 

 and numerous Illustrations. 8vo. \%s. 



The object of the first edition of this work was to place within the 

 reach of the people of the districts to which it relates, a popular 

 account of the more recent disccrveries in the geology and mineral 

 resources of their country, and at the same time to give to geologists 

 in other countries a connected view of the structure of a very in- 

 teresting portion of the American Continent, in its relation to 

 general and theoretical Geology. In the present edition, it is hoped this 

 design is still more completely fulfilled, with reference to the present 

 more advanced condition of knowledge. The author has endea- 

 voured to convey a knowledge of the strUcture and fossils of the 

 region in such a manner as to be intelligible to ordinary readers, 

 and has devoted much attention to all questions relating to the nature 

 and present or prospective value of deposits of useful minerals. 

 Besides a large coloured Geological Map of the district, the work 

 is illustrated by upwards of 260 cuts of sections, fossils, animals, 

 etc. " The book will doubtless find a place in the library, not only 

 of the scientific geologist, but also of all who are desirous of the in- 

 dustrial progress and commercial prosperity of the Acadian pro- 

 vinces." — Mining Journal. "A style at once popular and scientific. 

 . . . A valuable addition to our store of geological knowledge." — 

 Guardian.
