The statements here referred to, are those of Mrs.Graham, in a letter to Mr.Warburton, which has been published in the Geological Transactions Second Series volume 1 page 412, etc.; and the account is supported and illustrated by a valuable paper in the Journal of the Royal Institution for April 1824 volume 17 page 38 etc.) The writer of this latter article asserts that the whole country, from the foot of the Andes to far out at sea, was raised by the earthquake; the greatest rise being at the distance of about two miles from the shore.

The rise upon the coast was from two to four feet: at the distance of a mile, inland, it must have been from five to six, or seven feet, pages 40, 45.) M.Peron has attributed the great abundance of the modern breccia of New Holland to the large proportion of calcareous matter, principally in the form of comminuted shells, which is diffused through the siliceous sand of the shores in that country;* and as the temperature, especially of the summer, is very high on that part of the coast where this rock has been principally found, the increased solution of carbonate of lime by the percolating water, may possibly render its formation more abundant there, than in more temperate climates.

But the true theory of these concretions, under any modification of temperature, is attended with considerable difficulty: and it is certain that the process is far from being confined to the warmer latitudes.
