THE ESSEX FIELD CLUB. 85 Proceedings of the Geologists' Association. The President and Mr. Whitaker pointed out the value of this paper (alluded in a note in the present part) as a summary of the present state of knowledge on the subject. Any student wishing to gain an insight into the geology and palaeontology of the Crags of Essex and Suffolk could not do better than make this paper his guide. Thanks were voted to Mr. Harmer for his interesting communication. Photographic Survey of Essex.—Mr. A. E. Briscoe, B. Sc., Principal of the 'Technical Institute, then read a paper entitled "Proposals for a Photographic and Pictorial Survey of Essex, in connection with the Essex Museum of Natural History." This paper was published in full in the last part of the Essex Naturalist, ante, pp. 1-5. A letter was read from Sir Benjamin Stone, President of the National Photographic Record Association, in which the writer gave some useful hints on the subject, and cordially approved of the scheme for Essex. An interesting discussion was carried on by the President, Mr. G. Scamell (the Secretary of the National Association), Mr. W. Whitaker (Chairman of the Surrey Survey), Mr. Avery, Mr. W. Cole, Mr. F. J. Brand, and Mr. Briscoe. The Secretary suggested that Mr. Briscoe's paper should be printed in the Essex Naturalist, and that after a committee had carefully considered practical plans, a meeting should be called in the summer in some central place in Essex, when the proposal could be formally placed before the county. A cordial vote of thanks was passed to Mr. Briscoe, the President remarking that they were much obliged to him for affording the Club an opportunity of making a practical movement towards realizing a very fascinating idea. The Club's set of photographs showing the effects of the Essex Earthquake of April 22nd, 1884, was exhibited. THE 220th ORDINARY MEETING. Saturday, February 28th, 1903.
