DISCOVERY OF MAMMALIAN REMAINS AT GREAT YELDHAM. 115 first colour-printed map issued by the Geological Survey. I wish also to note its unprecedentedly low price of 2s. 6d; It is in the highest degree desirable that its merits and existence should be widely known as, should its sale be large, other maps, illustrating districts of similar size, will be published at similar prices. But that will occur only in the event of this map turning out to be a com- mercial success. And when we remember how many cheap and admirable Government publications remain unknown to thousands (who would purchase them did they know of their existence) owing to the utter neglect of Government Departments to give them any fair chance of being known and sold—a neglect that would ruin any private firm—I do not think you will charge me with unnecessarily taking up your time in calling attention to this new departure in Geological Maps.1 DISCOVERY OF MAMMALIAN REMAINS AT GREAT YELDHAM, ESSEX. By T. V. HOLMES, F.G.S., with notes by E. T. NEWTON, F.R.S., F G.S. TOWARDS the end of February, 1896, I received a letter from Mr. E. A. Fitch, enclosing one sent to him by Mr. T. Goodchild, of Great Yeldham Hall, in which the latter gentleman mentioned the discovery of bones, antlers, etc., in a brickyard close to Yeldham Railway Station. Mr. Fitch very kindly offered to go with me to the spot, and, accompanied by Mr. E. T. Newton, F.R.S., on behalf of the Geological Survey, we visited Great Yeldham on March 5th, 1896. On arrival, Mr. Goodchild at once conducted us to the brickyard about 200 yards west of the Railway Station, which is marked on both the old and the newer ordnance maps, and has thus evidently been a brickfield for many years. It had, however, at the time of our visit, a general aspect of disuse and decay, sheds and other buildings shown on the six-inch to the mile map being either ruinous or having disappeared, and the sections being obscured and overgrown. In the Geological Survey Memoir, on Sheet 47 (which includes Essex north of a straight line from the junction of the Lea and Stort to 1 Mr Holmes has kindly presented a copy of the map above described to the Forest Museum. It may be useful to add that the sole official agent for the sale of the Government Maps is Stanford, Charing Cross, London.—Ed.
