Photographs of eight Eoliths of one and the same shape, namely, with a chipped or worked tooth-like prominence, rendering the flint fit for use as a ‘borer’—photographed of half the actual size (linear measurement) from specimens found near Ightham, Kent, in the high-level gravel—which form part of the Prestwich collection in the Natural History Museum, Cromwell Road, London. Many others of the same shape have been found in the same locality. These and the trinacrial implements photographed in Fig. 4 are far older than the oval and leaf-shaped ‘palæoliths’ of the low-lying gravels of the valleys of the Thames, Somme, and other rivers.

Fig. 4.
Photographs of six Eoliths of the ‘shoulder-of-mutton’ or ‘trinacrial’ type—from the same locality and collection as those shewn in Fig. 3. The photographs are of half the length of the actual specimens. A considerable number of worked flints of this peculiar shape have been found in the same locality. Possibly their shape enabled the primitive men who ‘chipped’ and used them to attach them by thongs to a stick or club. The descriptive term ‘trinacrial’ is suggested by me for these flints in allusion to the form of the island of Sicily which they resemble. (Original).
