1. Those sharp or but slightly rounded at the sides, and presenting a pointed oval or _vesica piscis_ in section. 2. Those with flat sides. 3. Those with an oval section. 4. Those presenting abnormal peculiarities. In each subdivision there will, of course, be several varieties, according as the sides are more or less parallel, the blade thicker or thinner, the butt-end more or less pointed, and the edge flat, segmental, or oblique. There are also intermediate forms between these merely arbitrary classes. |99| [Illustration: Fig. 43.—Santon Downham, Suffolk. 1∕2] * * * * * I commence with those of the first sub-division, in flint. The first specimen I have engraved, Fig. 43, is a representative of a common type, and was found at Santon Downham, between Brandon and Thetford, on the borders of Norfolk and Suffolk, where, also, implements belonging to the Palæolithic Period have been discovered. The sides were originally sharp, but have been slightly rounded by grinding. The faces still show, in many places, the surface originally produced by chipping, but all projections have been ground away. |100| I have also a larger specimen, 9 1∕2 inches long, from the same spot, and found, I believe, at the same time. This form is of common occurrence in the Eastern Counties. I have specimens from Hilgay Fen, Norfolk (8 1∕2 inches), and Botesdale (7 inches), Hepworth (6 1∕4 inches), Undley Hall, near Lakenheath (5 3∕4 inches), in Suffolk. Some of these are ground over almost the entire face. A fine specimen (10 inches) is in the Woodwardian Museum, at Cambridge. In the Fitch Collection is a fine series of them. One of these, 9 3∕4 inches long, 3 1∕2 inches broad, and 2 1∕2 inches thick, weighing 3 lbs. 6 1∕2 ozs., was found at Narborough, near Swaffham. Another (9 1∕2 inches), weighing 3 3∕4 lbs., was found near Ipswich. A third (8 3∕4 inches) was discovered at Bolton, near Great Yarmouth. Others from 5 3∕4 inches to 7 1∕4 inches long, are from Beachamwell, Elsing, Grundisburgh, Aylsham, and Breccles, in the counties of Suffolk and Norfolk. That from the last-named locality has one face flatter than the other. There are others in the Norwich Museum, including one from Blofield, 8 1∕2 inches long. There are numerous specimens of this type in the British Museum. One from Barton Bendish, Norfolk, is 7 3∕4 inches long; another from Oxburgh, in the same county, 6 3∕4 inches. Others, 6 1∕2 inches and 5 1∕2 inches long, are from Market Weston and Kesgrave, Suffolk. The former is semicircular at both ends. Mr. A. C. Savin has a well-finished example (6 1∕2 inches) from Trimingham, five miles south of Cromer. The Rev. S. Banks, of Cottenham, had a fine specimen, of white flint, 8 1∕2 inches long, found at Stow Heath, Suffolk.
