 *[Footnote:

Toises. Eng. ft. Poulett Scrope, 1822, barometric, somewhat uncertain from the proportion between the diameters of the tube and cistern being unknown                   604      3862 Monticelli and Covelli, 1822                              624      3990 Humboldt, 1822                                            629      4022

Most probable result 317 toises, or 2027 English feet, above the Hermitage; or 625 toises, or 3996 English feet, above the level of the sea.

B. The lowest and southern margin of the crater opposite to Bosche Tre Case.

Toises. Eng. ft. After the eruption of 1794 this edge became 400 (426 Eng.) feet lower than the Rocca del Palo; therefore if we estimate the latter at 625 toises (3996 English feet)                                     559      3574 Gay-Lussac, Leopold von Buch, and Humboldt, 1805, barometric                                        534      3414 Humboldt, 1822, barometric                                546      3491

C. Height of the cone of scoriæ inside the crater, which fell in on the 22d of October, 1822.

Toises. Eng. ft. Lord Minto, barometric                                    650      4156 Brioschi, trigonometric, according to different combinations either                                     636      4066 Or                                                        641      4098

Probable final result for the height of the above-mentioned cone of scoriæ 646 toises, or 4130 English feet.

D. Punta Nasone, highest summit of the Somma.

Toises. Eng. ft. Schuckburgh, 1794, barometric, probably computed by his own formula                                      584      3734 Humboldt, 1822, barometric, Laplace's formula             586      3747 ]*
