Extract

At a time when those curious forms often assumed by the upper beds of limestone rocks are thought worth attention, and are brought forward by some geologists as evidences of sea-action, it may not be wholly without interest if I re-introduce a curiously moulded bed of this rock, occuring near Ulverstone.

Beete, p. 513.—Since writing the above, it occurred tame to turn to the memoir by Mr. Jukes on the River Valleys of the South of Ireland; and I fear the fact will scarcely be believed, that the description given there of the limestone of the Burren hills, so true to nature as it evidently is, had hitherto entirely escaped my attention.Google Scholar

There is palpable evidence of the truth of this in the small angular stones (one cannot call them pebbles or shingle) which may be found entangled amongst the grass-roots where the sod is thin. It will be seen that there is a remarkable tendency amongst these to terminate in points, more or less sharp; sometimes in one, awl-like; or in two or more, often closely resembling fossil teeth of fishes. Below, where these occur, are quantities of miniature “rockery stones” of every form and shape. There could not, certainly, be a greater proof, I think, of the absence of wave-action than in these extraordinary examples of limestone débris.Google Scholar
