of the Castle, they visited the Museum lately established, 
the old one having disappeared, and judging from the 
present fine collection of local fossils, it bids fair to establish 
a well-merited notoriety. The local collection of fossils 
from the Wren’s nest, containing some choice and rare 
Encrinites and Trilobites are well worthy of attention. 
Taking the route by Windmill hill to the Wren’s nest, the 
members were able to trace out the western portion of the 
Coal field, and the bosses of the Greenstone in that direc- 
tion, the most noticeable of which is that at Barrow hill. 
Near Parkes Hall and the water-works certain shale beds, 
with numerous fossils, were examined, and a valve of the 
rare “‘Chiton Grayii” was discovered. The local Geologists 
were of opinion that these shales belong to the Lower , 
Ludlow series, from the prevalence of certain forms which 
characterize that portion of the Silurians, though inter- 
mingled with others which also occur in the Wenlock 
limestone and upper Ludlow. Attention was also drawn 
to some interesting faults by which the limestone is cut off 
to the North West. Arriving at the southern end of the 
Silurian dome, the fine section of the well known Dudley 
limestone were carefully examined and numerous charac- 
teristic fossils especially Corals, were procured. Returning 
by the Old Park, a halt was made to examine the Ludlow 
beds, lately thrown out by some new sinkings now in 
progress, and a rich harvest of organic remains might have 
been reaped if time could have been spared to give them a 
careful examination.
