Paleontologists are largely indebted to Messrs. Meek and JL Worthen for their very careful researches in the Coal-Measures of Illinois, which have resultedinsuch large and valuable accessions to the fauna and flora of the Carboniferous formation. Not the least interesting of these has been the discovery of numerous organisms, which were first recognized and correctly described by themin1868 as the remains of spined Myriapods.

Probably from the great preponderance of interest attaching to the Devonian rocks of North and South Devon the Culm Measure rocks, constituting the great central table land, have been to a certain extent overlooked. The attempt to subdivide them by ascertaining their different lithological characteristics, and observing to what extent these characteristics are peculiar to definite horizons, Las seldom been made. We may, infact, sum up the literature of the subject with one notable exception—the late Prof. J. Phillipsinhis “Figures and Descriptions of the Palasozoic Fossils of Cornwall, Devon, and W. Somerset”—as bearing upon the position.of the series as a whole, or calling attention to some special point of interest.

In Decade III. Vol. II. of the GEOLOGICAL MAGAZINE, for 1885, at page 283, an abstract of a paper on “ Cone-in-Cone ” by Mr. John Young, F.G.S., of Glasgow, was given. The author of this interesting paper has kindly presented the writer with a copy of it, to which, since it was readinGlasgow last year, has been added some additional remarks, together with two very beautiful plates, by ‘ photogravure,’inillustration of some of his typical Scottish specimens.

The discovery of diamonds at Kimberley, South Africa, has proved to be a matter, not only of commercial, but of much geological interest. The conditions under which diamonds here occur are unlike those of any other known locality, and are worthy of special attention. The first diamond foundinSouth Africa wasin1867, when a large diamond was picked out of a lot of rolled pebbles gathered in the Orange river. This led to the “river diggings” on the Orange and Vaal rivers, which continue to. the present time.

The section exposing this stratum was discovered during an excursion made last June by Mr. W. Hill, F.G.S., and the author. It occurs in a quarry near West Row Ferry, about two miles west of Mildenhall;here a band of red marly chalk is seen near the entrance, dipping westward at a low angle, hut soon becoming horizontal and running along the whole face of the quarry, till it is cut off by a fault, which brings up lower beds on the southern side.

Observations extending over several years upon glacial phenomena on both sides of the Atlantic had convinced the author of the essential identity of these phenomena; and the object of this paper was to show that the glacial deposits of Great Britain and Ireland, like those of America, may be interpreted most satisfactorily by considering them with reference to a series of great terminal moraines which both define confluent lobes of ice and also often mark the line separating the glaciated from the non-glaciated areas.

At the last meeting of the British Association certain facetted pebbles derived from the Olive group of the Salt Range, and presumably of glacial origin, were exhibited and commented on. Some doubt appears to have been expressed as to their being due to glacial action. The following notes on these pebbles and the bed they were derived from may prove of interest.

The rocks of this area have been previously described by Professor Hughes (Geol. Mag. Vol. IV.), and some notes upon the same were subsequently submitted by myself to the British Association at Yorkin1881, and published in the Proceedings of the Yorkshire Geological and Polytechnic Society (Proc. Y. G. & P. S. N.S. vol. vii.). Further work was carried on this year, incompany with a party of Cambridge geologists, under the guidance of Prof. Hughes, and I have to thank him and them for much information, and for the opportunity of examining many specimens.
