BRIGHTON CLIFFS. 
31 
d. Base of the cliffs of chalk rock. 
A vertical section of the cliffs, about half a mile 
east of Brighton, is represented above. The lower- 
most bed is, — 
1. The Upper, or flinty chalk ; which consti- 
tutes about six or eight feet of the lower part of 
the cliff, and, dipping southward, extends to an 
unknown distance into the sea. The continuation 
of the chalk behind the calcareous bed is marked 
g in the sketch ; and is introduced to show the 
relative situation of the masses, but without any 
regard to proportion. 
2. Bed of fine sand, from three to four feet. 
3. Shingle bed, from five to eight feet. 
4. Elephant bed*, formed of the ruin of the 
clialk strata, with an intermixture of clay ; the 
harder masses are provincially termed Coombe 
rock ; — from 50 to 60 feet. 
* This name is given to distinguish it from the other calcareous beds, 
which do not contain remains of elephants.
