No. 3.—On the core of “blue shale,” numbered ‘‘ 49,” was a 
small portion of a fish bone or spine.’ 
No. 18.—The core numbered “246,” is not “blue marl and 
limestone,” as represented, but the usual red marls of 
the Keuper, with a patch of grey. So that the top of 
the Keuper comes in between 203 and 246 feet. 
No. 22.Sandy beds come in about 313’, and water was obtained . 
from them and from the gypsum beds described as 
“Conglomerate.” A core marked “ 366’” was very 
sandy. 
The following facts appear from this section, translated from 
engineering into geological language, that the Lower Lias beds 
are 219’ thick at this place, and consist of the usual blue Lias 
clays and shales with occasional alternating beds of rock. That 
the White Lias and Rhetic beds are represented and about 
14/ in thickness, and that the rest of the boring was carried 
_ through Keuper Marls and Sandstones to the depth of 179’, and 
that these latter rested on Pennant rock,
