Another and even more interesting example of this class has recently been brought to light by the Hon. W. O. Stanley, at Plas Newydd, not far from the great dolmen represented on woodcut No. 50.

It is a chamber or cist, 3 feet 3 inches wide by about 7 feot long, and covered by two slabs. Before being disturbed, the supporting slabs must have formed nearly perfect walls, thus distinguishing the cist from those standing on widely-spaced legs. Its principal point of interest, however, is the widely-splayed avenue of stones leading up to it, showing that it was always intended to be visited ; and still more curious are the two holes that were pierced in the slab that closed the entrance. The upper part of this slab is now broken off, but so much remains that it is easy to see that they were originally circular and about 10 inches in diameter. Such holed stones are very frequent in Eastern dolmens, and are also common in Cornwall and elsewhere ; but what their purpose may have been has not yet been explained.
