FIG. 4. 



Photographs of six Eoliths of the ' shoulder-of-mutton ' or trinacrial ' 

 type from the same locality and collection as those shown in Fig. 3. 

 The photographs are of half the length of the actual specimens. A con- 

 siderable 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).
