In 1853–6, when Mr. Sharpe published his monograph on the Cretaceous Cephalopoda of England, the various species were roughly placed according to the divisions of the Chalk formation as described by Conybeare and Philips. This, unfortunately, led to many mistakes: amongst others, Mr. Sharpe described Belemnitella mucronata as occurring “everywhere in the Upper Chalk of the South of England,” whilst Belemnitella quadrata is only noticed as occurring in the Middle Chalk of Kent, Surrey, and Sussex; the fact being that Belemnitella quadrata is not found in the Middle Chalk, and Belemnitella mucronata is restricted to the highest zone of the Upper Chalk.

IN a previous paper I have discussed the post-Tertiary Clays of Eastern England. In that paper I endeavoured to show that these clays, varying as they do in texture, composition, and contents, mark a varying geographical distribution and substratum rather than a succession of changes in time; that, so far as we can tell, they are for the most part on the same horizon, and interlock with each other, with occasional local overlaps; while they are united by one common element, namely, the presence of certain foreign boulders of the same general type in them all.

Since I joined this Society I have devoted special attention to Glacial Geology, commencing with an investigation of the Pleistocene deposits in the neighbourhood of Liverpool, and gradually extending my observations to adjacent areas, and finally generally to England, Wales, Scotland, and Ireland. I have therefore thought that the “Present Aspects of Glacial Geology” would form a fitting subject for my closing Presidential Address.

The prevailing type of schist in the south-east of Anglesey, for some miles to the north and north-west of Beaumaris, is a wavily foliated, pale-green, chloritic rock, the quartz in which, though more abundant than appears at first glance, is in a very fine state of subdivision. In a common variety, especially prevalent about Llanddona, quartz forms nearly the whole of the rock, but it is still in very compact seams, separated by partings of chlorite or mica.

A Slight earthquake of intensity IV, according to the Rossi-Forel scale, was felt in and near Exmoor at about 9 a.m. on January 23, 1894. Its interest lies, not so much in the seismic phenomena presented by it, as in its connection with the northern boundary fault of the Morte Slates.
