Note 92 — Chapter XV · SUBTERRANEAN HEAT—ITS POWERS ILLUSTRATED BY VOLCANOS.

See the elaborate work of Sir William Hamilton, entitled Campi Phlegraei, in which he gives a full account of the formation of Monte Nuovo, accompanied with colored plates. He has preserved two interesting narratives of the eruption written at the time by eye-witnesses. See also Lyell, Principles of Geology, vol. i., pp. 606-616.
