184 PHYSICAL GEOLOGY. 



Ber. Senchenb. nat. Ges. June 1874— June 1875 [pub. 1876], pp. 77- 

 133, with map of old glaciers. 

 Treats (1) of the action of glaciers and the formation of moraines ; 

 (2) of the history of the extension of old glaciers in Switzerland, &c. 



Mackintosh, D. Queries and Remarks relative to existing Ice- 

 action in Greenland and the Alps, compared with former Ice- 

 action in the N.W. of England and Wales, i^gp. Brit. Assoc. 

 for 1875, Sections, p. 76. 



Noticed, under a shorter title, in the Geological Record for 1875, 

 p. 185. 



On the geological meaning of the term " River-basin," and 



the desirability of substituting " Drainage-area," Rejp. Brit. Assoc. 

 for 1875, Sections, p. 75. 

 Drainage-areas are not " basins ;" the watershed as a rule does not 

 run along the highest ground, but high mountains often occur near the 

 centre of the area. The geological cause of this fact is alluded to.

Gives this name to material brought by water rising towards the 

 surface by solution of caleareoue beds or in faults. Describes, as thus 

 formed, granitic sand filling a fault near Beyn-es, a block of sandstone 

 in which was metamorphosed at the surface. Regards the red clay of 

 the French Drift and glauconitixj Tertiaries as partly dive to the same 

 cause. W. H. D.

Chiefly in criticism of Mr. Goodchild's views, and referring especially 

 to a tract of country between Halt whistle and Wark. The rocks are 

 alternations of thick sandstones, shales, and thin limestones, the "■ Whin 

 Sill" producing the boldest feature. The escarpments are pre-glacial. 

 Reasons are given why glacial action alone is not competent to produce
