The other Eeports (0, F, J, M) on the physical features, geo- 

 logy, and economic products of parts of Canada are not so extensive 

 as Eeport A ; but are carried out with the same great care and full 

 appreciation of the importance of exactness of both detailed and 

 general information to the well-being of the bread-winning colo- 

 nists, and knowledge-seeking geologists there and elsewhere. 



Eeport " C" is On an Exploration of the Finlay and Omenica 

 Rivers, by E. G. MacConnell. Eeport "F" On the Vicinity of 

 Eed Lake and Berens Eiver, Keewatin, by D. E. Dowling. 

 Eeport " J" is On part of the Province of Quebec, by E.Wells; 

 and on the Laurentian, north of the St. Lawrence, by F. D. Adams. 

 Eeport "M" treats of the Surface Geology of Eastern New- 

 Brunswick ; North- Western Nova-Scotia ; and part of Prince- 

 Edward Island, by E. Chalmers. 



G. E. Hoffmann in Eeport "E" gives the results of the Labo- 

 ratory work of the Survey during 3 894. Nearly 700 specimens 

 were received for examination ; and the Eeport gives the results 

 of such examinations, analyses, and assays as may be of general 

 interest. Miscellaneous minerals, mineralogical notes, coals, iron 

 ores, nickel and cobalt, marls, gold and silver, natural waters, and 

 miscellaneous rocks, &c, occur in the order of subjects. 



The very elaborate and useful Eeport " S " consists of the 

 Mineral Statistics for 1893 and 1894, by E. D. Ingall and H. P. H. 

 Brummell. The substances noticed are — grindstones, diatoma- 

 ceous (here termed infusorial) earth, asbestus, chromite, coal, 

 copper, graphite, gypsum, iron, lead, manganese, mica, nickel, 

 petroleum, precious metals, and miscellaneous. The estimated 

 value of the minerals and mineral products of Canada in 1893 was 

 $21,100,100 ; in 1894 $20,950,000. The value of the exports 

 of these materials from Canada in 1893 was $6,045,459 ; and the 

 countries to which they were sent are also tabulated. The imports 

 of similar materials into Canada in 1892-1893 were valued at 

 $25,377,824. 



This goodly volume of useful geological and economic informa- 

 tion has a clear Table of Contents of eight pages, and a full Index.

 LL.D.,F.R.S., late Lowndean Professor of Astronomy and Geometry in 

 the University of Cambridge. Vol. I. Edited by "William Grylls 

 Adams, Sc.D., F.E.S. With a Memoir by J. W. L. Glaisiiee, 

 Sc.D., F.E.S. (Cambridge : at the University Press.) 

 Dr. Glaisher, who contributes the appreciative biographical notice 

 prefixed to this volume (which occupies thirty-four pages), also 

 wrote the obituary notice of Prof. Adams published in the Annual 

 Eeport of the Eoyal Astronomical Society for February 1893. All 

 the circumstances connected with the memorable discovery of Nep- 

 tune are here given in great detail ; and appended are Prof. Challis's
