xii Journal of Proceedings. Saturday, May 29th, 1880.—Ordinary Meeting. The Ordinary Monthly Meeting was held in the St. John's Church Schoolrooms, kindly placed at the disposal of the Council by the Rector, the Rev. C. J. Ridgeway. The President occupied the chair. Upwards of eighty members and friends were present. The following were balloted for, and elected members of the Club :— Miss Alcock, Mrs. M. Smith, Messrs. John Finzi, J. M. Gawler, Charles J. Glass, Frank Jesse, Charles Thomas, F.G.S., Charles Welsh. The names of seven new candidates were read. Mr. Worthington Smith, F.L.S., exhibited six large and heavy Palaeo- lithic implements, found by himself in the Valley of the Lea, near London, and of the same age as the elephants and other animals sub- sequently mentioned by Mr. Walker in his lecture. These implements are found on both sides of the Lea Valley, generally in sand and gravel, and not unfrequently with bones of Elephas primigenius. Mr. Saward exhibited a remarkably pale form of Argynnis Euphro- syne (the "Pearl-bordered Fritillary Butterfly") from Ongar Park Woods. Mr. E. A. Fitch, F.L.S., brought up for exhibition and distribution amongst the members a large number of specimens of the usually rare Cress, Lepidium draba. This plant is a native of the middle and south of Europe, but is not admitted into the British list, being considered by Mr. Watson as an alien ; it has occurred in fields and on hedge- banks, at Swansea, St. Peter's, Ramsgate, and in Essex, but always rare, and appearing to be introduced. Mr. Fitch's specimens were from his fields at Maldon. The plant was first noticed twenty or twenty-five years ago, and is now very common. The roots penetrate to a great depth in the soil. Mr. Fitch was of opinion that the seeds of the plant had been introduced with foreign clover seed. Mr. Henry Walker, F.G.S, (author of "The Glacial Drifts of Muswell Hill and Finchley," "Saturday Afternoon Rambles, Rural and Geological," &c), then delivered a lecture entitled "A Day's Elephant Hunting in Essex." (Transactions, Vol. I., pp. 27-58.) Mr. Walker illustrated his lecture by reference to numerous maps, plans, and geological sections, some of which were new, and specially pre- pared for the occasion. He also showed some fine specimen fossils from his own collection. The lecture was listened to with deep atten- tion by the audience:, and Mr. Walker was much applauded at its close. The President said it was almost unnecessary for him to speak of thanks to the lecturer, they had already given their verdict in that hearty burst of applause. The lecture was well worthy of the attention it had received, and he had great pleasure in announcing that the Council had resolved to print Mr. Walker's essay, so that the members
