Coast west of Hastings. — The alterations and improvements on the coast west of Hastings 

 were so rapid, soon after the preceding pages 163. to 171. were written, that, within a few weeks, 

 an entirely new face of the cliffs was brought to light ; a great part of the original surface having 

 been cut away, so as to throw back the vertical section to a much greater distance from the sea, 

 while the debris were employed in raising a quay, by which the shore is now concealed. The 

 Rev. Granville Vernon Harcourt, who had examined the new features thus disclosed, was 

 so good as to point out to me several appearances, which proved that the structure of the shore 

 was not quite so simple as I had supposed it to be, though the sections above described, and that 

 represented in Plate X. b. fig. 3., are in the main correct. Several intermediate though slight 

 derangements occur between the principal fault at the White Rock and the site of the church west 

 of St. Leonard's ; and the whole of the phenomena show that the original stratification hereabouts 

 has been fractured and dislocated throughout, although the disjointed portions are seldom 

 widely separated. 



It would be impossible, without the aid of a map on a very large scale, to represent these 

 derangements, nor have they more than a local interest. The place of one of the principal inter- 

 ruptions between the White Rock and Warriors' Gate is represented in PI. X. b. fig. 3. ; and the 

 beds composing the group tims divided, which, on the east of that point, dip slightly towards 

 the sea (or to the west of south), could be detected in several places within (or north of) the 

 Marina at St. Leonard's, in the sides of the new roads and streets then in progress, inclining, ge- 

 nerally, to the north' Their identity could be traced by the aid of two thin beds of greenish Fuller's 

 earth, frequently concurrent, but sometimes about 4- or 5 feet apart, and separated by about 8 feet 

 of grey sand and sandrock, from a bed of dark grey clay, much charged with portions of lignite, 

 in which indications of vegetable structure were perceptible, but none so distinct as to indicate 

 the species. These beds are all superior to the Endogenite group of the White Rock ; and their 

 distance above that group, on the north-east of St. Leonard's church, was clearly seen to be 

 nearly the same as at the White Rock. At the roadside, on the east of St. Leonard's church, I 

 myself found a specimen of Endogenites, at the place mentioned by Mr. Parish from report. 



The greater part of the ground formerly above the White Rock had been removed by the 

 operations above mentioned, and the fault there was distinctly uncovered to the extent of several 

 yards. The strata which form the cliff at the brewery descend gradually to the sea, without 

 apparent disturbance, but the ruins of the superior strata, including numerous fragments of the 

 lignite bed, were mixed in great confusion on the western and upper side of the fault ; which 

 rising gradually towards the north-east, seemed to cross the valley there separating the cliffs 

 from those of Hastings Castle Hill, in a direction from about south 25° west to the east of north. 

 On that line a wide but not deep fissure, or ravine, could be discerned passing towards the place 

 called Bohemia ; and on the opposite side of the valley, a detached portion of confused matter, 

 including, as at the White Rock, masses of clay iron ore, was visible in a highly inclined position, 

 at the corner of one of the lanes descending from the Castle Rock to the marsh. It is not im- 

 probable that the fault may be continued further up the valley on the north-west of Hastings. 



Bones of Birds in the Wealden. — Mr. Mantell, in a short paper read before the Geological So- 

 ciety, June, 1835*, has shown by anatomical evidence that the bones found at Tilgate Forest, and
