industries are not referred to, but it must be understood 

 that the Eolithic tools persisted through these periods 

 for general purposes. . . ' 



The Fagnien. The implements of this industry were' 

 discovered at BonceDes, near Liege, Belgium, at an 

 altitude of 860 feet above sea level, and 600 feet above 

 the level of the River Ourthe. The Eoliths were found 

 in the clay and flints at the base of the deposits of 

 the upper Oligocene containing Cytherea Beyrichi, 

 Pectunciihis obovatus, etc. 



The Cantalien. This industry is that of Puy Courny. 

 A considerable number of implements have a bulb of 

 percussion. 



TJie Kentien. This industry is represented in 

 Harrison's pits in the Kent Plateau gravel at an altitude 

 of about 700 feet above the sea level. It is also found in 

 the thin spreads of Ochreous gravels on the chalk plateau. 

 It has also been found by Dr. H. P. Blackmore in the 

 deposits of the " high terrace " at Laverstock, near 

 Salisbury, and by the Rev. H, G. O. Kendall on Hackpen 

 Hill, near Marlborough.* The surface of the Kent 

 Plateau also yields numerous specimens of Eoliths of the 

 Flenusien division of the Neolithic period. These can be 

 readily distinguished from the Kentien specimens by their 

 patina, and from the fact that they are unrolled. Owing 

 to their being rolled to a considerable extent, the Kentien 

 Eoliths are among the most difficult to make out, and it 

 is no doubt due to this fact that acceptance of Eoliths in ■ 

 this country has made such slow progress. 



St. Prestien. The Eoliths at St. Prest are associated 

 with Elephas nieridionalis. They are found at the base of 

 the deposits of the middle terrace of the river valleys at 

 altitudes of between 100 and 200 feet above the present
