In the centre of Ross-shire, to the west and north-west of Ben Wyvis, there are large intrusive masses of granite gneiss lying in the midst of the sedimentary Moine schists. They have a N.N.E. strike and extend over a tract of country about 20 miles in length, from Loch Luichart, near Garve Station (Dingwall and Skye line), to Carn Bhren, within 3½ miles of Ardgay Station (Inverness and Wick line). A coarse augen gneiss with large elliptical eyes of pink orthoclase or perthite, sometimes 2 inches long, is the principal rock, but a finer-grained granite gneiss also occupies considerable areas, especially in the region of Carn Chuinneag (see Map, Fig. 1). Boulders of the augen gneiss have been widely distributed by ice, and are common on the shores of the Moray Firth, etc. For that reason the “Inchbae augen gneiss” has long been familiar to geologists, though little was known about the parent mass, except that gneisses of this type were exposed on the high road between Garve and Ullapool, particularly in the lower part of Strath Rannoch.

The British Museum collection has lately been enriched by two Cephalopods from the Chalk of Lincolnshire that seem to be worthy of notice; one being a new species of Pachydiscus (P. farmeryi), the other being referable to the genus Heteroceras.

The phenomena of ‘plate-crushing’ in the course of the growth of the ambulacra of the regular Echinoids have for many years been utilized for purposes of classification of those forms, but the similar features which exist among some of the irregular types have not been studied in such detail as to render them systematically useful. It is with a view to showing that the structure of the ambulacra in one group of the Echinoidea Irregularia can be relied upon as an index of the relationships of the various genera, that this note has been written. It makes no pretence at completeness, as the material and time available have not been sufficient to allow of an exhaustive study. But the results of those observations that have been made seem to indicate that among the Holectypoida it should be possible, with the aid of zonal collecting, to trace genetic series among the various species, and perhaps to bridge the gulfs existing between the genera, by a study of their ambulacral plating.

The Ross of Mull is a comparatively low-lying peninsula exposed to the storms and swept by gales from the Atlantic. On these rocky shores are occasional stretches of sand which frequently have been driven inland, forming dunes and patches of blown sand at intervals around the coast. Sometimes the sand is forced up the cliffs and deposited more than 100 feet above the sea, and there are places in the centre of the peninsula where the blown shell-material is quite a noticeable constituent in the soil.

During the last few weeks East Yorkshire seems to have been severely dealt with by wind and hail and flood, and in common with the rest of the area the cliffs have suffered. Geologists, however, are able to profit where others lose, and as a result of disasters can obtain useful information in reference to the structure of a district. Perhaps one of the most interesting exposures that has recently been made occurs at the south extremity of North Sea Landing, Flamborough, where a large amount of cliff has recently slid down on the beach.

In the year 1831 the famous mineralogist and chemist, Gustav Rose, described a mineral which he had observed in his travels in the Urals the previous year. He pointed out that he had found in the greenstones of the Urals crystals with the cleavages and the prism angle of hornblende, but with the external form of augite. The porphyritic crystals of these greenstones are sometimes hornblende, sometimes augite.
