lake near the summit of the mountain, called the Devil's Punch Bowl; which on account of its immense depth, and the continual overflow of water, is considered as one of the greatest curiosities in Killarney.—Mr Smith seems to think, that one of the best prospects this admired lake affords, is from a rising ground near the ruined cathedral of Aghadoe.

The lake of Killarney is otherwise called Long Lane, or Loch Leir, from its being surrounded by high mountains. Nennius says, that these lakes were encompassed by four circles of mines; the first of tin, the second of lead, the third of iron, and the fourth of copper. In the several mountains adjacent to the lakes are still to be seen the vestiges of the ancient mines of iron, lead, and copper; but tin has not been discovered. Silver and gold are said by the Irish antiquaries to have been found in the early ages; but this is somewhat doubtful, especially in any considerable quantity, though some silver probably was extracted from the lead ore, and small quantities of gold might have been obtained from the yellow copper ore of Mucruis. However, in the neighbourhood of these lakes were found in the early ages, as well as at present, pebbles of several colours, which taking a beautiful polish, the ancient Irish wore in their ears, girgles, and different articles of their dress and furniture.

a genus of stones belonging to the argillaceous class, found chiefly in Cornwall in England. Its texture is either lamellar or coarsely granular; the specific gravity from 2630 to 2666. It contains 60 parts of siliceous earth, 25 of argillaceous, 9 of magnesia, and 6 of iron. The greenish kind contains more iron, and gives a green tincture to the nitrous acid.
