50 Woodward— On the Bridlington Craq. ; 
a list, with figures and descriptions of the new species; but the 
intention was never fulfilled. 
In Young and Bird’s ‘ Geological Survey of the Yorkshire 
Coast,’ published in 1822, it is stated (p. 22) that ‘ In 1811, 
with a view to the improvement of Bridlington harbour, the 
alluvium which forms its bed was bored through. It was 
found to consist of a bed of compact clay, 28 ft. thick, and a 
bed of cretaceous flinty gravel, 15 ft. thick, beneath which was 
the solid chalk.’ But no mention is made of Tertiary: shells. 
Professor John Phillips, however, tells us that ‘ Professor 
Sedgewick, who examined the spot in 1821, discovered appear- 
ances on the north side of the harbour, which he supposed to 
indicate the presence of one of the strata above the Chalk.’ * 
Mr. Phillips repeatedly searched, without success, for these 
beds, until July 1828, when he found, below the level of 
half-tide, an enormous mass of dark, shaly clay, having the 
appearance of Lias, and containing species of Ammonites, Penta- 
crinus, and Avicula, which he was ‘at first disposed to think 
a portion of a Tertiary stratum.’ He had seen specimens of 
Pholas crispata washed ashore, ‘ full of coherent sand, unusually 
solidified,’ but to these he attached no importance.f 
About the year 1850, Mr. H. C. Sorby visited Bridlington, 
and examined the Crag deposit for the sake of collecting Fora- 
minifera. These were named by Professor T. R. Jones, and 
enumerated in Mr. Sorby’s paper, read at the meeting of the 
Geological and Polytechnic Society of the West Riding of 
Yorkshire, in July, 1857. (Proceedings, 1858, p. 559). He 
describes the situation and condition of the deposit much in the 
same terms as 1t was spoken of by Mr. Bean. 
More recently the whole of the mass described by Mr. Bean 
and again by Mr. Sorby, has been entirely removed or built 
over during the construction of a pier, and it has been suggested 
that the only remaining chance of obtaining the fossils of the 
Bridlington Crag consists in dredging, or other operations in 
the harbour. 
Mr. Leckenby, who formerly collected these shells more 
extensively than any one except Mr. Bean, considers the de- 
posit to have been lower in position than the Boulder-clay, 
* Prof. Sedgwick informs me by letter (June 10) that his paper, in which the 
Bridlington shell-beds are mentioned, was published in the Annals of Philosophy 
for 1826. He collected a good many of the shells, and might have easily filled 
a wheelbarrow with them at the time of his visit in 1821. But owing to their 
extreme fragility, and bad packing, the specimens did not even get so far as 
Searboro’ in safety.
