Phoenicians, and that their priests took advantage of this 
superstitions feeling, and, like some modern priests, 
"improved the occasion," and assigned to these vibrating 
stones the power of divination. Few of these stones can 
now be found on their poise in this country, most of them, 
like the cromleach, having been removed for agricultural or 
other purposes, or, worse still, thrown over from stupid 
curiosity. Of course the rocking stone, like the primitive 
cromleach, may have been frequently imitated by art, 
especially for religious objects. 
Here is a drawing of the celebrated rocking stone of 
Cornwall, called the " Logan Stone," it does not require any 
great knowledge of geology or mechanics to come to the 
conclusion that this was not the work of human hands 
originally. I say originally, for you all know that it has 
been thrown over and replaced with great labour within your 
own time. There is another way in which a natural rocking 
stone may have been gradually formed. Here is a sketch of 
what Professor Phillips, the distinguished geologist, calls an 
" erratic block," near Settle. It is not difficult to foresee 
that in the lapse of time not very remote the narrow base on 
which this rock now reposes securely, may be worn away by 
rain and frost, until the huge mass becomes detached, or 
poised upon a pivot so small as to allow it to oscillate like a 
rocking stone. 
A short discussion followed the reading of this Paper, 
when John Lubbock, Esq., F.P.S., of London, then pro- 
ceeded to read the second Paper — 
ON THE GEOLOGICO-ARCH^OLOGICAL DISCOVERIES IN DENMARK, 
SWITZERLAND, AND FRANCE. 
Archaeology forms the link between Geology and History — 
the past and the present. If in its more recent portions it is
