BRITISH ISLES. 29 



Below this comes shale (with occasional thin coal), then a bed of 

 sandstone, the Quarry Hazle or the Pnidham Stone ; below this is the 

 Four-fathom Limestone. This last is everywhere characterized by the 

 presence of Saccamina Carteri. The relation of the Whin Sill to the 

 strata is noticed, and a list of fossils found in the limestones is given.

The Cretaceous Rocks of England. Trans. Watford Nat. 



Hist. Soc. vol. i. pt. i. pp. 1-13, 5 woodcuts. 

 Treats of the general distribution of the Cretaceous rocks, and shows 

 by means of a map the relations which the South Downs, North Downs, 

 and Chiltern Hills bear to one another. It is pointed out how the 

 Wealden beds suggest a distribution of land and sea very different from 

 that which now obtains. The L. Greensand, Gault, and U. Greensand 

 are each commented upon. The Chalk is then considered, its physical 

 features indicated, its structure and origin described, and lastly the 

 relation it bears to the higher beds of the London Basin, and the position 

 of Watford in that Basin, shown in a section from Tring to the Weald.

Mackintosh, D. On some important Facts connected with the 

 Boulders and Drifts of the Eden Valley, and their Bearing on the 

 Theory of a Melting Ice- Sheet charged throughout with Rock- 

 fragments. (Abstract.) Quart. Journ. Geol. Soc. vol. xxxi. pp. 

 692, 693. 

 Calls attention to the distribution of boulders in the district. Boulders 

 of Criffell granite are limited to a few hundred feet above the sea-level 

 on the N. and W. borders of the lake-district mountains. ShapfeU 

 granite does not reach above 1500 feet (?) on Stainmoor. These facts 

 are inconsistent with the theory of an ice-sheet 2300 feet thick. The 

 Eskers show traces of having been piled up rather than thrown down. 

 There is evidence that existing ice-sheets are pure, and do not contain 

 such a mass of material as the old ice-sheet is supposed to have dropped.
