I have collected somewhat similar blades to that here engraved, though of rather smaller dimensions, in the ancient encampment of Maiden Bower, near Dunstable; and I have several found on the surface near Lakenheath and Icklingham, Suffolk. I have seen one of the same character, which was found near Ware, Herts. General Pitt Rivers found in the Isle of Thanet[1516] two lance-heads, curiously like this and the preceding figure. [Illustration: Fig. 247.—Cambridge Fens. 1∕2] A far more highly-finished blade, but still preserving the same general character, is shown in Fig. 247. The original, of brown flint, was found in the Cambridge Fens, and is now in my own collection. Though ground on some portions of both faces, apparently for the purpose of removing asperities, the edges are left unground. They are, however, very carefully and delicately |335| chipped by secondary working to a regular sweep. I think this instrument must be regarded rather as a form of knife than as a head for a javelin or lance. In size, and to some extent in shape, it corresponds with the more crescent-like or triangular tools described under Fig. 256. I have a rather smaller example from Bottisham, ground along one side only. This correspondence is still more evident in a blade now in the Blackmore Museum, Salisbury, of nearly the same shape but somewhat less curved on one edge than the other, which has been ground along the more highly curved edge. It was found at Hamptworth, near Salisbury. A narrower form of blade is shown in Fig. 248. The original, of flint weathered nearly white, was found at Scamridge, Yorkshire, and is preserved in the Greenwell Collection. It is, as will be observed, slightly unsymmetrical in form, so that it would appear to have been intended for a knife rather than for a lance-head. A remarkably fine specimen in the same collection, found at Flixton, Yorkshire[1517] (5 1∕8 inches), is in form much like that from Scamridge. A part of the edge towards the point on the flatter side is slightly worn. There is a considerable diversity of form amongst the instruments of this character, some having the sides almost symmetrical, while others have them curved in different degrees, so much so as to make the instrument resemble in form some of the crescent-shaped Danish blades. In a specimen which I possess, from Ganton Wold, one side presents the natural crust of the flint along the greater part of its length, and has been left unworked; the other side has been chipped to an obtuse edge, which is considerably bruised and worn. I have others from Suffolk, sharpened by cross-flaking on one edge only. Some such knives are rounded at one or both ends instead of being pointed. A blade from the neighbourhood of Bridlington, in my collection, is pointed at one end but rounded at the other, where also the edge is completely worn away by attrition. In the case of another symmetrical and flat blade,
