234 at $$a$$, Fig. 121, the other at $$b$$, in the western transept—both not far from vertical, and right down through window and door opes to the ground level, from the roof. These were originated, the Sacristan informed me, by small thread-like cracks (filone) in 1851, but were widened and lengthened now, in December 1857. a is now about 0.75 inch open near the top, and the roof of the apse has been sufficiently injured to require struts betwixt ceiling and floor. The dislocation of the roof here, indicates a certain amount of emergence in the wave-path (but the fissures do not indicate any distinctly), 10° or 12° at most.

The direction I derive from them is 34° 30′ W. of N. There are upon various points of the cathedral and attached buildings many slender iron crosses, the iron flat bars of about 1 1/2 inch $$\times$$ 3/8 inch thick, as in Fig. 122, none of which present any signs of having been bent or twisted. They were all confined, however, by small diagonal stays of round iron, about 1/4 inch diameter. In the noble old cloister court, a long stone, part of the shaft of an old column that had leaned against a wall running nearly N. and S., was overthrown, and indicated a wave-path of about 60° W. of N.

Fissures, at the Tribunale, gave a wave-path 67° W. of N. These fissures also afforded pretty decisive evidence of the
