The specimen of Fossil Wood in flint, figured in Pl. IX. of the Geological Magazine, from a drawing by Mr. Crozier, was presented to the Oxford Museum by Sir Woodbine Parish, K.C.H., to whose intelligent liberality the public collections of England are greatly indebted. It was obtained from the Chalk of Winchester.

At the last meeting of the Society, Mr. Plant made statements respecting the supply of so-called fossil shells from the Drift at Macclesfield, of a striking and curious character: he warned geologists against certain specimens, on the grounds that some were only recent shells sold as fossils, and others, though bearing the appearance of Drift-fossils, were not only spurious as such form Macclesfield, but were not even fossils at all, being nothing but the results of an elaborate system of importation and manufacture: forgeries, in fact, to meet a new demand. Mr. Plant allowed that some of these frauds were well calculated to deceive even geologists, and quoted a statement that they had been successful at the Museums of London, Liverpool, and Manchester. Besides the simple introduction of recent shells, he specially reported a process of fecthing such shells from recent beaches at Liverpool, Southport, or Ireland (even the use of West Indian African shells), the breaking-up of the same, and the subjection of the fragments to fire or acid, and a subsequent treatment by friction in a basket with gravel, ‘to give them the true Drift-character and the necessary redtinge.’

All geologists admit that the Lake-district of the North-west of England has been several times under the sea since the first upheaval of the alternating sedimentary and volcanic rocks of which it is composed; and few would be disposed to question that during the repeated processes of elevation land subsidence, whether continuous or intermittent, the sides of the mountains and valleys of this district have been long exposed, at different levels, to the action of waves, tides, and currents. We have reason to suppose that the duration of the last or intra-glacial submergence was at least as long as the time which has since elapsed; and if during the latter the sea has done so much to indent and modify our coasts, may we not expect to find the most obvious traces of its former denuding influence in regions which have risen above its level? Yet some of the pluvial, fluvial, glacial geologists of the present day would soon reduce the sea to a subordinate rank in the list of causes, were it not for the masterly advocacy of marine denudation which, with fresh arguments, may be found in the successive editions of the works of Sir Charles Lyell and Sir R. I. Murchison.

In the GeologicalMagazine, No. VII., Mr. C. B. Rose described the Brick-earth of the Nar Valley. To the list of Fossils which he gave at pp. 11 and 12, we can now add some minute but interesting forms, namely, four Bivalve Entomostraca and three Foraminifera. The former (all new species), determined by Mr. G. S. Brady, of Sunderland, are—
