that a former powerful but transient current denuded the surface of 

 the bare rocks in many parts, and at the same time distributed 

 broken materials along a zone of limited width," etc., etc. {id. p. 358). 



Another fact cited by Murchison is the curious way in which the 

 flint drift is accumulated in the transverse valleys by which the 

 rivers Arun, Adur, Ouse and Cuckmere escape from the Weald 

 through the Chalk to the sea, and exhibits ancient mounds of drift, 

 arranged irregularly and at different altitudes upon their banks 

 from 20ft. to 100ft. above the present rivers. " A glance," he says, 

 " at any of these materials at once bespeaks the tumultuary nature 

 of their origin, for none of them contain rounded or water-worn 

 pebbles." 



At Peppering, about 80ft. above the Arun, and midway in the 

 gorge of the chalk, bones of an Elephant were found, as stated by 

 Dr. Mantell. In the defile of the Arun the promontories of North 

 Stoke and South Stoke are just in such relative positions as we may 

 suppose would have arrested or thrown off to the opposite sides 

 masses of detritus hurled along the valley ; and Peppering, being a 

 bay opposite to the round promontor}' of Arundel Park, is therefore 

 a spot where we might look for a collocation of drift with bones. 

 The more open and straighter chalk-valleys of the Adur, with no 

 marked promontories or masses, was little likely to arrest much 

 drift, which has chiefly been translated to the sea-board " {id. p. 360). 



Again, " I believe that the detritus in and around Pease Marsh 

 was chiefly the result of disturbances of the adjacent strata, whilst 

 broad and torrential bodies of water were moved along under the 

 escarpment of the North Downs and translated the debris into 

 natural depressions " {id. p. 378). Again, speaking of the angular 

 chalk flint near Gomshall, he says, '' As no streams have ever de- 

 scended over these hills of sandstone, since the present configuration 

 of the land and denudation of the country were effected, I equally 

 refer them to the same agency of drift as that which swept greater 

 volumes of them into the adjacent hollows" {id. p. 379). 



Again, " Fossil bones have been found at and near Folkestone, 

 at heights varying from 80 to 110 feet, not in different beds, but 

 always in the same broken flint debris. They have also been 

 detected in an upper combe or recess in the chalk escarpment nearly 

 two miles west and by north from Folkestone, and at an altitude of 

 not less than 222 feet above the adjacent sea. . . . With the fact 

 before us, that these fossil bones lie at once upon the bare rock in 

 situ, without any deposit between it and the drift in which they are 

 commingled, it seems impossible to explain their collocation (even 

 if we put their position out of the question) by supposing that they 

 were tranquilly buried under a lake, or fell from the banks of any 

 former stream. In those cases it would indeed have been miraculous, 

 if ruminants and carnivores had assembled themselves at a particular 

 moment of time to be interred, like a 'happy family,' in one thin 

 course of detritus, and at the bottom only of the sedimentary matter ! 

 To my mind, the circumstances of the same drift being placed at 

 such difi"erent levels at Folkestone, and of its sloping up from the
