Its greatest length stood transverse to the general wave-path, and it has suffered much. Its walls present fractures complicated by the double shock; but those whose planes approached a north and south direction, gave good measures of angle of emergence, which appeared a good deal less, down on the deep clays, than up on the rocky eminence of the town.

The average of the measurements taken from fissures and fractures, some of which were in the portions of the monastery seen in Photogs. No. 223 and No. 224 (Coll. Roy. Soc.), gave an emergence of 18° to 20° from the north, or $5 1⁄2$° to $7 1⁄2$° less in the clays than in the limestone rock.
