A sandstone statue of St. Leonardo, in the Capella Sta. Anna, on the north side of the church, stood elevated on a pedestal, in a niche on the north wall, in front of which was a stone and stucco slab or altar-table. (See Photog. No. 281, Coll. Roy. Soc. and Figs. 3 and 4, Diagram No. 282 bis.) It stood loose upon its base, 7.78 feet above the floor level, and was thrown in a direction, which finally was 162° 30' E. of north, but which, by marks upon the altar-slab and east walls, &c., seen in the Photog. No. 281, indicated that its first projection had been in a path about 144° E. of north, and that then, in pitching forward head foremost, over the edge of the altar-slab in front of the niche, it had altered the plane of its descent, to one more south, and, at the same time, thrown a complete somersault before it reached the floor, upon which it was found lying with the feet towards the south, and broken in two. The original height of the figure was 3½ feet. It weighed entire, by careful estimation, about 160 rotuli = 314 lbs. The centre of gravity, being about 1½ foot above the base, and the centre of oscillation over the front edge about 2 feet above it, it is not conceivable that its descent, to the position in which it was found, should have been made without the intermediate somersault. This so perplexes the effects of the original throw, that any calculation as to velocity, founded upon the horizontal distance, would probably prove fallacious. It might have reached its distance shown, viz. 7.45 feet from the front edge of the pedestal (having slided and turned over together, on the front edge of the altar-slab), by a force only just sufficient to upset it; and for this a
