black, both externally and internally. This sort is frequently found 
with much wood on the surface of the stones ; and, most frequently, 
the internal parts of the stone are found to contain wood still existing 
in a soft state. Of this kind, two very large pieces are mentioned. 
The one was a stone, weighing ^00 pounds, which was found two 
miles from Lough ^^'eagh, on the side towards the river Camlin. 
This specimen appears to have been, externally, complete stone ; but, 
internally, evidently woody. The other specimen was as heavy as 
two men could lift, and the reverse of the former ; the outer coat 
being of a woody nature, and the internal part entirely stone. The 
woody coat of this stone, when first found, was at least a foot thick, 
except at the ends. The stony parts of these masses are of a dark 
grey, approaching, in some parts, to a blue colour ; but are generally 
stained yellow on the outside, from their laying in a bed of gravel. 
These stones are chiefly found at a point called Ahaness, in the 
county of Antrim ; half a mile south of the mouth of the river Glen- 
evey. The bank at Ahaness is twelve feet high ; between the bottom 
of which and the lowest water-mark in summer, there is a space of 
about ninety feet ; which space, in winter, is sometimes covered with 
water. Upon digging a pit in this place, it appeared that the upper 
stratum is of red clay, four feet deep ; the second stratum is of stiff 
blue clay, four feet deep ; the third stratum is formed by a black 
wood, lying in flakes four feet deep ; and under this is clay again. 
From the top of the stratum of wood to the surface, is a depth of 
seven feet ; and before the water of the lake encroached so far on the 
land, it appears to have been nineteen feet. 
In a paper of Mr. James Simons, contained in the Transactions 
of the Royal Society*, it is asserted, that the white wood-stones are 
generally found in the ground, at from about two to six miles dis- 
tance from the lake, and sometimes very deep in the earth. The
