Revieivs — Geological Survey of Scotland. 273 



Under the heading of Economic Geology there will be found 

 a general account of the rich metalliferous veins for which the 

 island is noted, and a careful description of the very numerous 

 mine workings and trials that have been carried out in exploiting or 

 testing these veins. The book is illustrated by very numerous plates, 

 figures, and sections. 



We congratulate the author upon this very excellent and well- 

 prepared volume. But greater attention should be given by the 

 printers to the reproduction of the illustrations in the text, which 

 still leave much to be desired. The collotype plates are admirable, 

 and mark a distinct advance in the publications of the Geological 

 Survey.

THIS memoir describes the geology of Lower Strathspey, a 

 district embracing 432 square miles in the counties of Elgin 

 and Banff. Special attention is given to the development of the 

 topographical features of the region. The metamorphic and igneous 

 rocks are described, and a section is devoted to the petrography of 

 the area by Dr. J. S. Flett. In connection with the Old Red 

 Sandstone of Lower Strathspey, reports are given in the Appendix 

 by Dr. R. H. Traquair, F.R.S., " 0-n the Fishes of the Old Red 

 Sandstone," and Mr. R. Kidston, F.R.S., on the fossil plants of the 

 Old Red Sandstone of Scotland. The glacial deposits and economic 

 products are described. The three process plates are excellent. 

 A bibliography is given, and an index completes the work, but 

 the geological map (Sheet 85) does not accompany the memoir.
