The President's Address. 101 Arctic animals. I hope to have an opportunity of enlarging upon this subject on some future occasion. Our Field Meetings cannot but have left pleasant memories with us all. In spite of unfavourable weather on many occasions, they have always been well attended, and their success is largely due to the efforts of the eminent gentle- men who have acted as our conductors. The best thanks of the Club are due to Sir Antonio Brady, Professor Boulger, Dr. M. C. Cooke, Major-General Pitt-Rivers, Mr. B. H. Cowper, Mr. D'Oyley, Mr. Worthington Smith, and Mr. Henry Walker ; whilst upon our Honorary Secretary has not only devolved the organization of these meetings, but likewise the preparation of those excellent reports which have appeared in the Woodford Times, and which we shall many of us peruse with the interest of personal experience as now published in our "Proceedings." Among the most memorable of these excursions was the visit to Ilford in July, under the leadership of Sir Antonio Brady and Mr. Henry Walker, on which occasion most interest- ing collections of flint implements and other objects of Palaeolithic and Neolithic age were exhibited by Sir Antonio Brady and Mr. Worthington Smith ; and Mr. A. R. Wallace favoured us with a brief sketch of his views on the great question of geological climate which have recently appeared fully elaborated in his admirable "Island Life." It would be quite out of place to attempt here to lay before you any of the lines of argument adopted by Mr. Wallace in support of his theory, but it will be instructive, as show- ing the rapidity of the onward march of science, if I just mention one of his main conclusions, in so far as it bears upon a statement made in my inaugural address delivered last February. In speaking of the glacial epoch (i.e., the last glacial period, with its alternations of warm periods), I stated that the causes of these wonderful conditions of climate were of an astronomical nature, thereby of course indicating the occurrence of winter in aphelion (brought about by the precession of the equinoxes) during a period of great excentricity of the earth's orbit. This theory, due to Dr. Croll, has long been held by our most eminent
