220 REV. R. A. BULLEN, B.A., ON EOLITHIC IMPLEMENTS. 
DISCUSSION. 
The Cuatrman.—Before inviting the Members present to com- 
mence the discussion, I may say that I think you have already 
by your applause anticipated me in proposing a vote of thanks, 
which we all owe to the lecturer. 
It is a subject that I am not qualified to diseuss—or hardly 
at all—but he has shown himself to be a perfect master of know- 
ledge respecting it, and he has given us a most valuable lesson in 
geology, as to the various formations in which these flint imple- 
ments of different form and appearance are found. 
I will now ask Professor Rupert Jones to address the meeting. 
Professor Rurert Jonus.—I really cannot tell you anything 
more than Mr. Bullen himself has so clearly and definitely put 
before you. 
There are one or two little points on which I would say some- 
thing. 
~ Asa geologist, I should have liked the author to have given 
more importance, in a popular kind of way, to the height of the 
Wealden dome that did exist. It is not so easy for people to 
fancy, or imagine, the real condition of things, as shown on the 
diagram ; but although it was some 2,000 or 3,000 feet in elevation, 
I believe, you must remember that the same movement, the 
same crush, the same lateral pressure that brought that up, as a 
mere crumple of a carpet, raised the Ardennes Mountains ten times 
as high. So that there is nothing so very wonderful in it to a 
geologist. 
Koliths and paleoliths sometimes seem to be almost muddled 
up together—not by our friend the author, but by people in 
general. Asa matter of fact they are found together in some 
cases, though not quite undistinguished; but they may be 
found in one place together, and people say they are all of one 
form; but eoliths are the very earliest condition in which a 
man can use a clean flint stone, or pebble, with slight degrees 
of modification which are necessary to make it useful. The pale- 
oliths have been still more mixed up, and possibly people who 
made the paleoliths were making eoliths originally in the same 
way, and therefore you find the two together.
