Plate V. 



Elevation of the cliffs at Hastings in Sussex, from the White-rock on the west, 

 to Cliff-end on the east. The ancient town of Hastings is situated between the 

 West and East cliffs ; the greatest part of what lies between the West-cliff and 

 the White-rock having been built lately. On the top of West-cliff are the ruins 

 of the Castle. 



Letters of reference, placed on the cliffs, point out the details given in the 

 paper, p. 31, etseq. At the White-rock, the mamillated calciferous sandstone 

 is on a level with the sea at d: it then rises, and is seen on the top of the cliff at 

 d, under the Lime-kiln ; again at g,g, in East-cliff; and a-tf,f, at Cliff-end. The 

 sloping surface, partly covered with grass, under this, at e, e, is the dark-coloured 

 shale (see p. 33). The perpendicular surface at East- and West-cliff, Ji, h, shows 

 the soft sandstone, in which many caves are excavated ; for the fine white sand, 

 of which the rock consists below this, is slate-clay and shale, i, i. At k in West- 

 cliff, is seen the place where the latter bed was well exposed, in cutting down the 

 cliff to build the Bazaar- /, I, in East-cliff is another bed of sandstone ; and below 

 it, at /w, m, are seen the lowest strata visible, consisting of sandstone and shale, 

 with clay-iron-stone and carbonized vegetables.
