find their subterranean course to St. Michael's Cavern at Pertosa. There are several apertures, and the waters which before their plunge, turn some primitive old "mo- linas," appear to fall to a great.depth. The rock, where visible, shows extremely rapid erosion by the water, as well as evidence of immense dislocation and denudatiou at former periods, when the great valley was drained dry over it, by the gradual rending of the gorge of Oampostrina. The Palazzo Palmieri is fiasured diagonally in every wall more or less, those in tho north and south walls being the most formidable. A large wedge-haped mass, carrying with it a portion of the roof; is thrown from the S.W. quoin of the front, and a large portion of the south external wall , is prostrate and thrown to the south. In Fig. 1, Diagram No. 175, the form, position, and angles, of the principal fiasures found in the west front are show, looking eastward, entering beneath the "Portoue," and looking back or westward. The ti,__ures formed above the archway in the north and south wall of the interior facade, parallel to the front, are seen in the Photog. No. 177, and in the sectional sketch (No. 178) takeu on the line A B (on plau), and looking westward. The south external wall,  to , had been thrown to the south, and the upper part lay between t and k. This is shown, in part, in Photog. No. 180 (0o11. Roy. Soc.), as seen from the balcony of the staircase, directly opposite the entrance gateway, and is shown in elevation in Photog. No. 179, looking eastward. In all these the general directions and angles of the fissures are correctly exhibited. There are some fissures, in .all the walls, but the great mass are in those omning north and south.
