A celt of the same section, but of peculiar form, with the sides curved slightly inwards, and tapering considerably to the butt, is shown in Fig. 57. The sides are flat, but have the angles slightly rounded; a narrow flattened face is carried round the butt-end. It would appear to have been made from a calcareous nodule found in some argillaceous bed, like the septaria in the London clay. Both of |116| its faces present a series of diverging cracks, of slight depth, apparently resulting from the dissolution of calcareous veins in the stone. It was found at Nunnington, Yorkshire, and now forms part of the Greenwell Collection. The original of Fig. 58 was discovered at Burradon, Northumberland, where also the fine flint celt, Fig. 47, was found. This likewise is in the Greenwell Collection. It is of porphyritic stone, and has the angles of the flat sides slightly rounded. Another, in the same collection, 4 inches long, from Doddington, in the same county, is of similar character. Celts of much the same shape and size have been found in the Shetland Isles; one of these, 5 1∕2 inches long, from West Burrafirth, is in the British Museum. A similar form is found in Japan.[387] [Illustration: Fig. 58.—Burradon, Northumberland. 1∕2] [Illustration: Fig. 59.—Livermere, Suffolk. 1∕2] Fig. 59 shows a celt of much the same kind, found at Livermere, near Bury St. Edmunds. It is formed of a close-grained greenstone, and is in my own collection. The angles at the sides are slightly rounded. I have others of nearly the same size and of similar material, found near Cirencester, and at Soham and Bottisham, Cambs. Greenstone celts of about this size, and with the sides more or less flat, so as to range between Figs. 48 and 58, are of not uncommon occurrence in the Fen country. Mr. Fisher, of Ely, has one, found near Manea, and several from Bottisham. I have one, of felstone, 3 1∕2 inches long, found at Coton, Cambs., one side of which presents a flat surface 3∕8 inch wide, while the other is but slightly flattened. One (4 3∕10 inches) was found near Torquay, Devon.[388] A still more triangular form, more convex on the faces, and having |117| the flat sides much narrower, is shown in Fig. 60, from a specimen in the Greenwell Collection, found at Ilderton, Northumberland. It is formed of a hard, slaty rock or hone-stone. The angles of the sides are rounded. In the National Museum at Edinburgh are two implements of greenstone (2 3∕4 and 3 inches) of nearly similar form to Fig. 60, but having the sides sharp. They were found in the Isle of Skye.[389] [Illustration: Fig. 60.—Ilderton, Northumberland.] A smaller celt of the same character, 2 1∕2 inches long, found in a cairn at Brindy Hill, Aberdeenshire,[390] is in the British Museum. One 2 5∕8 inches long, from Sardis,[391] in Lydia, and in the same collection, is of much the same form, but rounder at the sides and less pointed at the butt.
