FIG. 3. 



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 ' palaeo- 

 liths ' of the low-lying gravels of the valleys of the Thames, Somme, and 

 other rivers. (Original).
