NOTES AND QUERIES.

not uncommon. Mr. Roberts' remarks also led me to infer that the specimens 
he had obtained or had seen from Cradley were either P. Lloi/dii or P. Lewisii. 
Now I obtained some twenty specimens or more, and all these were P. 
rostrattis ; in fact I did not meet wdth one specimen of P. Lewisii or P. Lloydii. 
I would further remark that with regard to Cradley, Cephalaspis is by no means 
so abundant as its cousin, Pteraspis, though I did obtain three or four tolerable 
heads. Let me also inform those who are about to visit this quarry (and I 
hope many are), that if they are not content with the proceeds of their own 
labour they may obtain specimens both of Cephalaspis and Pteraspis from one, 
Jacob GiU, a respectable Scotchman residing on the spot, and who has obtained 
many fine specimens. I hope now that I have shown that Cradley is a little 
more worthy of a visit than Mr. Roberts makes out. Its situation, too, is so 
convenient, that many ought to visit it from Malvern, the distance between the 
two places being barely seven miles. — I remain, yours, &c., E. R. Lankestek. 
■ Geology of Huddersfield. — In reply to your question of a " Young Geo- 
logist" in the July number, I may mention that along the Yorkshire coast 
from Spurn Point to Hartlepool the strata belongs to the Secondary Division, 
except a small portion called the Bridlington crag, discovered by the late Mr. 
Wilkinson, of Bridlington Quay. The strata above alluded to are overlaid by 
Drift ; the greater proportion of which consists of a purple clay, mixed with 
fragments of " almost every kind of rock," both water-worn and sharp and 
angular, and varying from pebbles to boulders of large size and weight ; along 
with these are sometimes found bones of Mastodon, Elephant, Irish Elk, &c., 
and here and there implements of flint. 
At Spurn the beach is low and shingly. Kilusea crag and a new cave are 
ereat attractions between Dimlington Hill and Holmpton, where is a freshwater 
deposit ; and the like occurs at Witheningsea, Sandley Mere and Grinston Garth. 
Near Kornsey there is a submerged forest. At Skipsey, Barmston, and 
Auburn, various bones, of extinct animals are met with, as also are freshwater 
shells in abundance. When the tourist arrives at Bridlington he can exa- 
mine the chalk in the various quarries at that place, and freshwater shells 
are to be found in the cliff on both sides of Bridlington Harbour. 
The Bridlington crag is met with near the north side of the north pier ; but 
this deposit can seldom be worked, owing to its being covered by sand and 
gravel thrown up by the sea. Some good specimens of the fossils are in the 
museum of Arthur Strickland Esq., at Bridlington Quay. Two miles north- 
east of Bridlington Quay is Sowerby, where, in the chalk, a little below high- 
'water-mark, the collector will be rewarded with a fine series of fossil sponges, 
fee. This locality must be visited from Bridlington, that being the safest 
road to Sowerby Cliffs. The next point of attraction is the great cave at 
Elamborough, called " Robin Lythes Hole," and three hundred feet long by 
•and ninety feet high ; besides which, there are to be seen large pillars of 
chalk, which once formed the entrance to other caves of even larger dimensions. 
Erom Elambro' the geologist must retrace his steps to Marton station, and pro- 
ceeding to Speeton (four miles), will there find the far-famed Speeton Clay, some- 
times considered as equivalent to the Gault, very rich in most beautiful fossils. 
•Skirting the " beck," will be found red clay and chalk overlying a bed of greenish 
trey chalk ; the red chalk rising from the sea shore at about three miles from 
peeton, &c. No more can here be stated about this singular stratum of 
Red Chalk, but much more may be seen and found by a careful examination 
than has hitherto been reported in the Rev. Mr. Wiltshire's account. Yet that 
gentleman's paper wiU De a guide; " The Speeton Clay is succeeded by the 
nrst member of Middle Oolite, the Coral Rag, and Calcareous Grit, which 
rocks form that remarkable and dangerous rock called Eiley Brig. From 
^his point northward the strata continue to rise above the level of the sea, and
