8. The Geological Structure of the North-west Highlands of 

 Scotland ; by B. N. Peach and John Horne, with penological 

 chapters by J. J. H. Teall, edited by Sir Archibald Geikie. Mem. 

 Geol. Surv. Great Britain, Glasgow, 1907. 668 pp., 66 figures 

 and 39 plates in text ; 13 petrological plates and a geological 

 map (1:253,440) at end of volume. — Although Gunn, C lough 

 and Hinxman are named on the elaborate title page, which is 

 much abbreviated in the above citation, this fine volume will be 

 universally known as the work of the two senior authors, who for 

 twenty years past have been associated in the laborious task of 

 working out in detail the extraordinary structures of the north- 

 west Highlands of Scotland. The chief headings are : Lewisian 

 Gneiss, Torridonian, Cambrian, Post-Cambrian Movements, and 

 Eastern Schists: it is under the fourth of these headings that the 

 extraordinary overthrusts of the region are described. In con- 

 trast to the extreme disturbance of the zone of dislocation, it is 

 remarkable to see, a little farther west, the undisturbed and unal- 

 tered Torridonian resting on buried hills of Lewisian gneiss in 

 perfectly normal unconformity. The volume is finely illustrated 

 with photo-plates. w. m. d. 



9. Schmidt's Geological Sections of the Alps. — American geolo- 

 gists who are interested in modern interpretations of Alpine 

 structure will find a valuable series of colored sections in several 

 pamphlets by Prof. C. Schmidt of Basel, as follows : Bild und 

 Sax der Schioeizeralpen, which appeared as a supplement to Vol. 

 XLII of the Swiss Alpine Club, 1907 (F"inckh, Basel, 5 francs) 

 containing, besides a beautifully illustrated text, a small geological 

 map and a remarkable group of profiles illustrating the extreme 

 extension given to the modern idea of overthrust folds. JFuhrer 

 zu den Exkursionen der deutschen geologixchen Gesellschaft im 

 sudlichen Schwarzivald, im Jura tin d in den Alpen, An gust, 1907, 

 by Schmidt, Buxtorf and Preiswerk (Schweizerbart, Stuttgart, 5 

 marks), contains a number of more detailed sections, as well as 

 the group of general sections. Ueber die Geologic des Simplon- 

 gebietes und die Tektonik der Schioeizer alpen (Eelog. geol. 

 Helv., IX), gives a number, of detailed sections and a general 

 geological map of the Alps between St. Gotthard and Mont 

 Blanc. Tektonische Demonstrat.ion*bilder (to be had of the 

 author, 1 franc), gives some of the same Alpine sections and sev- 

 eral additional sections for the Vosges and the Schwarzwald.
