The earlist, and almost the only published, notice of the ‘Bridlington Crag’ is contained in a single page of London's ‘Magazine of Natural History’ for 1835, vol. viii. p. 355, entitled ‘A Short Account of an Interesting Deposit of Fossil Shells at Burlington Quay, by Mr. William Bean.’ Writing from Scarbro’ on March 30th, Mr. Bean states that ten days previously he had made a geological excursion to ‘Burlington Quay,’ when Mr. Walter Wilson, an intelligent lapidary of that place, directed his attention to a deposit of fragile and broken shells, which the late high tides had exposed on the north side of the harbour, and near the pleasure-ground called the Esplanade. On arriving at the spot, he found a heterogeneous mass, only a few yards long, and as many high, composed of sand, clay, marine shells, and pebbles of every description, chalk and flint being most abundant. The colour and appearance of this shelly bed resembled London Clay, but the fossils had the character of those found in the Crag formation. It would be necessary to collect a greater number of species than he had then obtained, and to exercise much caution before the geological position of the bed could be truly determined; but of this much he was certain, that the shells were coeval with, if not of higher antiquity than the Crag. More than half of them could not be referred to any existing species. The writer concluded by mentioning that he had already made a second visit to the place, in company with Dr. Murray, and reaped an abundant harvest.

In Plate 1 of professor Owen's invaluable memoir on the Archæopteryx (Phil. Trans. 1863) the fifth vertebra behind the Acetabula is seized upon as the first of the caudal series. In Pl. 3, fig. 5, of the same memoir, we have the delineation of a young Ostrich’s pelvis; and in that figure the first post-femoral joint is marked as the commencement of the true tail; eight such joints being, even in the young bird, embraced by the posterior processes of the iliac bones.

Few amongst the Fish-remains preserved to us in the Secondary roacks are more commonly met with than those of Sharks of the genera Acrodus and Hybodus; yet, not-withstanding the frequency of their occurrence, we have but little exat knowledge of the from and affinities of the fish to which these remains beleonged. Their cartilaginous skeletons have, expecting a few fragments, altogether pershied; and it is quite impossible to guess at their outlines, undefined as these were either by scales or hard plates. Nay, more, the remains that are known of these extinct forms present such great differences from the corresponding structures of living fish, that, although a relationship to a single existing genus has long been indicated, the degree of that affinity is still very uncertain.

The age of the sandstones and conglomerates, containing copper and other ores, at Alderley Edge, has until lately been a matter of some uncertainty; and, as far as I am aware, no detailed account of the formation has yet been published. Some few years since I made an examination, in company with Mr. E. W. Binney, F.R.S., of the beds in question, and on the first opportunity afterwards I hazarded an opinion, at a meeting of the Geological Society of Manchester, that the copper-bearing beds were referable to the age of the Lower Keuper Sandstone of the Trias. My brother-geologists, I had reason to think, received this opinion with some amount of distrust, as the rock, being in some places a quartzose conglomerate, and in others a soft whitish or yellowish sandstone, had much more the appearance of Bunter Sandstone than of the uppermost member of the Trias. My conjecture was not made, however, at hap-hazard, but was founded on evidence of position and petrographical characters, as the conglomerates, with their underlying bands of red shale, reminded me of the basement-beds of the Keuper division in the somewhat distant region of Alton Towers, and the Churnet Valley in Staffordshire.

In the well-known section at Whitecliff Bay the Chalk and the various Tertiary beds are seen to succeed one another in regular order northwards; and the dip, at first very high, so that the beds are almost vertical, decreases in that direction.
