214 Mr. Richardson's Observations on the Locality of the Hyracotherium. 



cotherium ; but as his previous account of the plastic clay series is not alluded to 

 by him in this communication, it has been thought advisable to give the following 

 abridgement. Only the sandy beds of the formation occur on this part of the 

 coast. They first appear from under the London clay about three quarters of a 

 mile eastward of Heme Bay, and continue to rise in an unbroken line until they 

 attain the altitude of 100 feet at the Old Haven, whence they irregularly decline 

 to a very low cliiF, over which the sea breaks at exceedingly high tides, about one 

 furlong west of the Recuiver towers. From this point they again rise to the height 

 of sixty feet under the towers, where the sands terminate abruptly as a cliff, form- 

 ing only low land and marshes to the rise of the chalk near Birchington. 



The following sections are given of the beds near Bishopstone, and those which 

 constitute the cliff on which are situated the Recuiver towers. 



Compact sandstone, at intervals 6 feet. 



Brown sand 15 — 



Second shelly bed I5 —

Teeth and other remains of fishes are found in the sands of the formation ; also 

 testacea, though generally too decomposed to be preserved for examination, but 

 the author found a Trochus, a Cerithium, and a Venus. Iron pyrites are sparingly 

 dispersed through the strata ; and a few dark lines indicate the existence of carbo- 

 naceous matter. 



The chalk rises from beneath the plastic sands at an angle of five or six degrees ; 

 but the upper or flinty chalk is stated to have been removed throughout nearly the 

 whole district from Birchington to Margate, the debris resulting from its destruc- 

 tion being spread over the hills as well as in the valleys. — Editor.]
