not uncommon. Mr. Roberts' remarks also led me to infer that the specimens 

 he had obtained or had seen from Cradley were either P. Lloydii or P. Leivisii. 

 Now I obtained some twenty specimens or more, aud all these were P. 

 rostratus ; in fact I did not meet with 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 Gill, 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. Lankester. 



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. Kilnsea crag and a new cave are 

 great attractions between Dimlington Hill aud Holmpton, where is a freshwater 

 deposit ; and the like occurs at Witheningsea, Sandley Mere and Grinston Garth. 

 Near Hornsey 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, 

 &c. 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 

 rey 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 will be a guide," The Speeton Clay is succeeded by the 

 first member of Middle Oolite, the Coral Rag, and Calcareous Grit, which 

 rocks form that remarkable and dangerous rock called Eiley Brig. Erom 

 *his point northward the strata continue to rise above the level of the sea, and
