THE GEOLOGISTS' ASSOCIATION
This Association celebrated its sixtieth anniversary on December 7th, 1918, when a Lecture was delivered by Major Sir Douglas Mawson, in the Architectural Theatre, University College, Gower Street, W.C.1, on "The Glaciation of Antarctica." During 1919 several important papers have been read, including the Annual Address by the President, Mr. J. F. N. Green, B.A., F.G.S., on "The Vulcanicity of the Lake District" and a paper on "Old Age and Extinction in Fossils," by Dr. W. D. Lang. Three parts of the Proceedings for 1919 have already been published containing a full report of Dr. Lang's paper, another paper by the same authority on "The Evolution of Ammonites," and the Presidential Address by the Past-President, Mr. George Barrow, F.G.S., on "Some Future Work for the Geologists' Association," which is an interesting and exhaustive study of the post-Eocene deposits of clays, sands and gravels, older than the River Terrace deposits. The Proceedings also contain accounts of the excursions made to certain places of geological interest during the year. At Easter an excursion was conducted to the Bristol District by Professor S. H. Reynolds and Mr. J. W. Tutcher, and at Whitsuntide the Association visited the Isle of Wight, under the guidance of Mr. G. W. Colenutt and Mr. R. W. Hooley. Llangollen was selected as the district for the "Long Excursion" in August, and about forty members spent a week in the study of the Ordovician, Silurian and Carboniferous systems of the neighbourhood. Mr. L. J. Wills, M.A., F.G.S., was the Conductor. Excursions were also made to Sevenoaks, Farnham, Berkhamstead, Codicote (Herts), St. George's Hill (Weybridge), Box Hill, Headley Heath and Epsom. The first meeting of the Winter Session was held at University College on November 7th, which was followed by a conversazione. Many exhibits were made of Fossils and Flint Implements. Mr. Llewellyn Treacher showed a fine specimen, one of the largest known, of a flattened, pear-shaped late Chellean implement, 12½ inches long, recently found in the Maidenhead gravels; a slab of shale studded with Graptolites, from the Tarannon of Peebleshire, was exhibited by Mr. R. J. A. Eckford; and Mr. J. Francis showed many fine examples of Jurassic Ammonites and Belemnites, illustrating chambers, septa, siphuncles and sutures.
