masses, and of the tubular cavities within, generally approaches 

 to an oval figure. The specimens diflFer very much in size ; being 

 from less than one foot to nine feet in length ; the stony matter 

 within occupying, in the largest, about 5 feet, with a thickness 

 of 6 to 9 inches, and a general width of about I foot. This stony 

 nucleus was invested with a coating of coal, from -rVth to -A- an inch 

 in thickness, which wtis found to exti nd, at both extremities, 2 

 or 3 feet beyond tiie nucleus. The external surface of the coaly 

 covering is uniform and smooth, of a light brown colour, and glis- 

 tening: but neither in this surface, nor in the coal beneath, could 

 any traces of organization be discovered. Thin polished slices of 

 the nucleus were exhibited. 



A ledge which is observable on the shore below St. Leonard's, 

 may be traced thence in the cliffs, through the site of the church, 

 and westward to the summit of the hill above the Sussex Hotel. In 

 this group also, a specimen of Endogenites was found by Wood- 

 bine Parish, Esq. ; by which and other circumstances it is identi- 

 fied with that of the White-rock ledge: and from its including also 

 a thin band of siliceous conglomerate, abounding in the remains of 

 animals like those of the well-known grit of Tilgate Forest, — the 

 teeth and bones, especially, of the Iguanodon of Mantell, — there 

 can be no doubt of its geological identify with some of the strata 

 of that place. 



The coast sections, described in this paper, will be useful in 

 assisting to determine the order of succession in the Hastings 

 Sands; a point of difficulty, from the great similarity, both in the 

 rocks, and the included fossils, of the several members composing 

 that formation: and the author thinks it deserving of inquiry, 

 whether the Ashburnham group, which has hitherto been referred 

 to the lower portion of the Hastings Sands, may not be identical 

 with some of these groups upon the shore, — and, consequently, may 

 not belong in reality to the upper part of the formation. 



A letter was afterwards read from Woodbine Parish, Esq., ad- 

 dressed to George Bellas Greenough, Esq., P.G.S., accompanying a 

 collection of fossils made by Mr. Parish during the last summer at 

 St. Leonard's. 



These fossils Mr. Parish states were principally found in a layer of 

 very compact conglomerate varying from 1 inch to 3 inches in thick- 

 ness, and forming a crust upon a stratum of sandstone which ex- 

 tends from the new church to the western extremity of St. Leo- 

 nard's. They consist of remains of the Iguanodon, and other Sau- 

 rians, and of the Lepisosteus Fittonii. 



Mr. Parish also describes, in his letter, a submarine forest, which 

 he traced at low water, from the western extremity of St. Leonard's 

 to the headland at Bulverhithe, and he is of opinion that it is a con- 

 tinuation of the submarine forest which occurs off Hastings. The 

 trees, he says, are chiefly oak, and appear to have fallen towards 

 the sea. 



In the peat forming part of the deposit he found hazel nuts, a 

 variety of seeds, and the remains of beetles and other insects. No
