84 THE ESSEX FIELD CLUB. Tri-colour Photography and its application to natural history work, the making of lantern slides of insects, flowers, and micro-photographs, &c. Mr. Turner's exposition was illustrated by many beautiful examples of the process, shown by the lantern. A very considerable discussion on methods and results ensued, carried on by the President, Mr. John Spiller, F.C.S., Mr. F. H. Varley, F.R.A.S., Mr. Briscoe, B.Sc, Mr. Crouch, the Lecturer, and others. But as these remarks pertained mainly to points of photographic practice, they are unsuitable for reporting here. The object of Mr. Turner's exposition was to show what a beautiful and practical method had been placed in the hands of the naturalist. We have also the Sanger-Shepherd process, the methods and results of which were so well shown at late meetings of the Club by the inventor and by the slides illustrating the lectures of Professors Poulton and Meldola. Mr. Turner was most heartily thanked for his interesting and well presented demonstrations. THE 219th ORDINARY MEETING. Saturday, January 31ST, 1903. This meeting was held as usual at the Technical Institute, Stratford, at 6.30 p.m., the President in the chair. Photographs of Colchester Charters and Essex Churches.—Mr. J. Avery showed a set of the photographs (32 in number) made by Mr. J. C. Shenstone, F.L.S, (one of the Vice-Presidmts of the Club) of the Charters of the Borough of Colchester, from Richard II. downwards, together with many other Charters and records of historical interest. The photographs were made for and presented to the New Town Hall, and were printed by the carbon process, but a very few copies (12) were struck off and acquired by residents of the town. Mr. Avery's copy is believed to be the only one outside the borough. Mr. F. J. Brand exhibited an interesting album of photographs of Essex Churches. Palaeolithic Implements from Leyton.—The Secretary exhibited on behalf of Dr. Frank Corner, F.G.S., a set of over 30 Palaeolithic Implements found in making excavations in the valley of the Fillibrook at Leyton, Essex. Some of them, from the gravel about 6 feet down, were much rolled and water worn; but at the 9 feet level sharper specimens occurred, and this level appeared to have been the "living floor" of the makers of these implements. Dr. Corner had presented the whole series to the Club's Museum. Mr. W. Whitaker, F.R.S., made some remarks on the implements, which he considered to be very interesting, coming as they did from one locality. It was most desirable for finds of this kind to be kept together. The President, in suggesting that Dr. Corner should be thanked for his donation, alluded to the excellent scientific work of Mr. Worthington Smith in collecting and studying the implements unearthed in particular spots. Care in this respect had enabled Mr. Smith to prove the existence of working-places or "Palaeolithic Floors" on the margins of the old Thames and Lea. The vote of thanks was cordially given. Later Tertiary History of East Anglia.—The President said that Mr. W. F. Harmer, F.G.S., had sent for the library a reprint of his paper on "A Sketch of the Later Tertiary History of East Anglia," published in the
