“Nearly all the sandstones arc caleareons, especially those at F, and 
helo\y this hed, in the face of the enttinf^, the stratilieation is ohsenred hy 
caleareons tufa de})f)sitod from the dri])pin!T water. Fossil plant remains are 
found, either in, or just above or l)elow the clay hands, or else in the fine- 
grained sandstones, and are absent from the dark, line-grained shales. The 
strata arc almost horizontal, in no jdace exceeding a dip ol 5°, the strike 
being about E. and W.”

A. — Soft sandstone. 
15. — Dark .shales containing nodules, in which the fossil fish and plants were found. 
C. — Light coloured shales containing soft clay liands and small nodules, in which were found imperfect 
impressions of plants. 'I'lie nodules generally were found to contain a nucleus of stems of plants. In one case 
the iiodule had formed round a piece of selenite (gypsum). 
“ The nodnlcs in Bed B are distributed throughout the whole of the 
lied, but those containing the hsh were found, principally, near the top. At 
place marked (1) I found a block weigliing about 1 ewt. containing numbers 
of ZTuio shells (both large and small ones), and in breaking some of the shells 
they were found to contain Avater. 
“ At the point marked (2) part of the remains of a Labrynthodon (now 
in Museum) Avere found. At the place (3) occurred a large fish in a A'cry 
large nodule (ranch broken). The other fish 1 found above (3) and close to 
Bed C.”
