The conclusions as to the stratigraphical relations of the volcano of Rhobell Fawr, north of Dolgelley, in Wales, which were arrived at by Mr. T. H. Holland and myself, have received kindly recognition from Sir Archibald Geikie in his Presidential Address to the Geological Society of London in 1891; and we may now consider that the great ring of Arenig volcanoes, Cader Idris, the Arans, Arenig Fawr, and Moelwyn, rose upon an area already shattered by sporadic Cambrian outbursts. After again visiting Rhobell Fawr in 1892, in company with Mr. Mervyn Marshall, I feel able to give some account of the rocks that build up that volcano and its outlying fort-like masses.

Since the year 1885 the various zones of the Gault at Folkestone have been systematically examined by one of us for the purpose of recording the Foraminiferal fauna of that deposit; the report upon which is now being published in the Journal of the Royal Microscopical Society.

For many years the writer has wished for the means to bring about some uniform system of glacier observation, and more especially the collection of data respecting ice-movements in British Colonies, and territories under British influence. When we think of our mountains in the Dominion of Canada and in New Zealand, and the vast ranges of the Himalayas (these last we shall before long hear about from Mr. Conway), it seems a great pity that such promising fields should not be adequately worked. In an article in the Alpine Journal, for February, 1891, the writer sketched a plan of operation; and in the same Journal, for February, 1893, asked for a committee to communicate with such Colonial Governments as could take part.

The very great importance of the issues involved if we are to make any definite progress in the study of the later deposits must be my excuse for this reply to Mr. Stirrup's letter. He says that the only available material for discussing the results of the expedition of Toll and Bunge to the Siberian islands is an abstract published by Schmidt some months ago. In this he is surely mistaken.

On the morning of December 20, 1892, a severe earthquake was felt in the neighbourhood of Quetta in British Balúchistan. Some of the remarkable effects of this shock have already been described in a paper in “Engineering” for May 19, by Mr. R. W. Egerton, the executive engineer in charge of the Shalabagh division of the North-Western Railway. The present note is founded partly on this paper, and partly on further details contained in letters written by Mr. Egerton to his father, Sir. R. E. Egerton, K.C.I.E. and to myself. It will thus be seen that everything that is of value in this paper is due to Mr. Egerton's careful observations; my own part has simply been to edit these notes and to select from them, those particulars which appear to me of most interest to geologists.
