Page 36 - Kinahan's work, now before us, aims to give a more detailed account of the strata, and of the facts to be observed in the field, thus acting as a guide to the geologist in his explorations. As the general features of the Geology of Ireland were pointed out at some length in the notice of Prof. Hull's book (see GEOL.
Page 29 - Florence of Worcester says : — "On the third day of the nones of Nov. 1099, the sea came out upon the shore, and buried towns and men very many, and oxen and sheep innumerable.

They appear to be destitute of animal remains, but the greater part of this immense group of strata is filled with the silicified remains of a multitude of forests.
Page 26 - because the lands covered by seas were originally at different altitudes, that the waters have risen, or subsided, or receded from some parts and inundated others. But the reason is, that the same land is sometimes raised up and sometimes depressed, and the sea also is simultaneously raised and depressed, so that it either overflows or returns into its own place again.
