FOSSILS OF THE GALT. 
malm of Surrey cannot for a moment be doubted ; 
not only is there a perfect agreement in their phy- 
sical characters, but also in their geological position, 
and organic remains. The marl of Folkstone is 
said, by Mr. Phillips, to contain 30 per cent, of car- 
bonate of lime ; and that of Ringmer, upon being 
submitted to the action of acids, indicates a like 
proportion. 
FOSSILS OF THE GALT. 
Organic Remains. — The fossils of the gait, like 
those of other argillaceous strata, are remarkable for 
their beauty, the pearly covering of the shells being 
in most instances preserved. They consist of seve- 
ral species of ammonites and hamites ; nautili ; a 
delicate pellucid helemnite ; many species of nucu- 
Ice, inocerami^ &c. and of turhinolia^ or caryophil- 
lea. Two of the most characteristic fossils are here 
delineated : viz. Inoceramus .sulcatus^ and concen- 
tricus. 
green sand, and the cliffs on the east of the town are from eighty to 
ninety feet high, the upper part of which, for a considerable distance 
from their termination at Copt Point, consists of the blue marl. Crys- 
tallized sulphate of lime occurs in this bed, and numerous remains of 
shells with their pearly lustre still preserved. There can be no doubt 
that this deposit is altogether analogous to that underlying the chalk at 
Mailing in Kent, in Cambridgeshire and Oxfordshire, and which, in the 
latter counties, is provincially termed Galt. — Geological Transactions, 
vol. V. p. 37. 
* At the foot of the chalk hills near Godstoue, and Bletchiugley, the 
gait rises from beneath the grey marl ; and I have collected from these 
localities precisely the same species of ammonites, belemnitcs, micuhc, 
Szc., as those which occur at Ringmer and Laughton.
