REPORT ON FLINT IMPLEMENTS OE THE NORTH-EAST 
OF IRELAND. By W. J. KNOWLES. 
[Read January 14, 1889.] 
In former communications to the Academy^ I have shown grounds for 
there being two series of flint implements in Ireland. On further 
research I see no reason to depart from the decision I had come to ou 
the occasions referred to. The implements of the older series, which 
are the subject of the present report, are found embedded in an 
aqueous deposit known as the raised beach, often many feet from the 
surface. The worked flints of the series consist chiefly of flakes and 
cores ; but we find, in addition to these, pear-shaped implements, not 
flat, but rather rudely circular in section, and others longish coarsely 
dressed, somewhat pointed at both ends, and often triangular in sec- 
tion. While a few of the implements have been found in the aqueous 
deposit itself, many have been obtained from the material spread out 
on the shore in cases where the raised beach has suffered denudation. 
Some of the implements approach the palaeolithic type, but others 
show a different form. Such animal remains as have been found in 
association with the worked objects are insufiicient for determining 
their age, but there is sufficient evidence to show that they are older 
than the ordinary flint implements of Ireland, such, for instance, as 
are to be found in the Academy's Museum, and therefore I shall 
content myself for the present by continuing to speak of them as the 
older series. 
In the raised beach at Larne the flakes and cores are to be found 
as low as eighteen feet from the surface. We would, no doubt, find 
them at a lower level, but that is about the greatest depth to which 
any section has been opened. They are covered with a whitish 
weathered crust, in some cases three-eighths of an inch in thickness, 
and in several cases I have obtained flakes and cores in situ at various
