I Left London on the 3rd of August, 1875, and next morning was sailing down the muddy estuarine waters of the Humber towards the German Ocean en route for Gottenborg. On either side was a long line of flat coast.

In two papers, by Messrs. S. V. Wood, jun., and F. W. Harmer, recently read, before the Geological Society,—alluded to by Mr. Belt, in the GeologicalMagazine for April last,—this Rootlet-bed at Kessingland has been referred to, and described as an interglacial shallow valley deposit; of an age posterior to the Contorted Drift or Lower Boulder-clay, lying in a trough excavated out of the Chillesford Clay. To make their description more intelligible, the authors (Messrs. Wood and Harmer) subjoin a sketch-map—in their combined, paper “Observations on the Later Tertiary Geology of East Anglia,” read November 8th, 1876—and indicate by a broken line the connexion of this trough with the existing (!) valley systems of the rivers Waveney and Yare—which are here mainly cut out of the Chalky Boulder-clay and Middle Glacial Sands—thus apparently assuming that, before the Middle Glacial Sands and Chalky Boulder-clay were deposited, there were valley systems occupying much the same positions in this immediate locality as there are now, with the addition of the supposed continuation of the interglacial valley of the Waveney in a south-easterly direction to Pakefield and Kessingland.

By the permission of the Director-General of the Geological Survey I am enabled to publish a short account of the results arrived at during a detailed examination of the cliffs between Weybourn and Mundesley on the coast of Norfolk.

Sp. Chars.—Tooth bidentioulated with a re-entering angle between the denticles; sides sloping down to the lateral angles; anterior profile convex; posterior profile concave. The most prominent portion of the anterior surface is at the centre of the inferior margin of the crown, where it becomes bowed-out, whence the surface gradually recedes to the cutting edge of the crown on the one hand, and more rapidly towards the root on the other.

On the 6th March, 1874, I communicated a paper on the “Geology of the Neighbourhood of Nottingham” to the Geologists' Association, which was subsequently printed in extenso in their Proceedings. Up to that time I believe the definition laid down by the Government Survey, and imported into text-books, of the distinction between the so-called Permian and the New Red Sandstone formations had not been called in question very prominently. Like other students of geology, I myself accepted in good faith the dictum as to a great break existing between the two formations, indicating, of course, an enormous period of time.

In a paper read before the Geological Society of London, Prof. Hull proposes, as generally applicable to the whole of Great Britain and Ireland, a new classification of the Carboniferous rocks, as follows:

In Chile and adjacent regions of South America, Mr. Darwin, in his “Geological Observations,” has described a great series of Mesozoic rocks, which he calls the “porphyritic formation,” and which shows an interesting resemblance to certain rocks in British Columbia. These I had provisionally designated in my report in connexion with the Geological Survey of Canada for 1875, as the Porphyrite series, without at the time remembering Mr. Darwin's name for the Chilian rocks. Many of Mr. Darwin's descriptions of the rocks of Chile would apply word for word to those of British Columbia, where the formation would also appear to bear a somewhat similar relation to the Cascade or Coast Range, which that of Chile does to the Cordillera.

The following brief notes on rare, little known, or occasionally new fossils, in some cases anticipating more detailed descriptions, may be of interest to the readers of the GeologicalMagazine.
