The subject of this notice belongs to a family of which several members have occupied high positions as clergymen and scholars. His father, the Ven. John Fisher, the early friend and patron of Constable, was Archdeacon of Berks, Canon of Salisbury, and Vicar of Osmington and Gillingham in Dorset; his grandfather, the Rev. Philip Fisher, D.D., was Master of the Charterhouse; and his great-uncle, the Rev. John Fisher, was preceptor to the Princess Charlotte, and subsequently Bishop, first of Exeter and afterwards of Salisbury.

The Green River Shales of Wyoming have long been noted for their numerous and beautifully preserved fossil fishes. Fragmentary traces of bird-remains have been met with in the same horizon from time to time since the year 1869, when the first fossil feather reported from North America was obtained by Dr. F. V. Hayden.

I have from my boyhood been intimately acquainted with Snowdon and its neighbourhood, and for some years past I have been investigating the geology of the district in a systematic manner. In doing this I have paid particular attention to the lake basins, and shall in the following pages give an account of some of my investigations as far as they have gone. I say as far as they have gone, because I hope in the future to make by means of a level more accurate measurements than can be made with a pocket aneroid; and I also hope that next Summer the lakes and tarns will be sounded either by myself or by someone else; for at present we know nothing about the depth of Llyn dur Arddu, next to nothing above that of Glaslyn, and very little about Llydaw, though that little is of great importance.

One of the results incidental to the meeting of the British Association for the Advancement of Science at Dover in September last was a visit paid to Folkestone by the members of Section C (Geology). Among the ladies present was Miss Caroline Birley, well known both as a traveller and for the deep interest which she has always taken in palæontological research; she is also the owner of an excellent private museum of minerals and fossils, mostly collected by herself. Miss Birley was fortunate in obtaining from Mr. J. Griffiths, the resident geological collector, a small but well - preserved carapace of a Gault Crustacean, believed at the moment to be the usual Necrocarcinus Bechei (Deslongsch., sp.), a form about as abundant in that locality as the Palæocorystes Stokesii (Mantell, sp.). The specimen, enlarged twice natural size, is clearly depicted in the accompanying illustration in the text.
