Note 34 — LETTER V.
Reading edition
Bracini, in his account of the eruption of 1613, says, that he found many sorts of sea shells on Vesuvius after that eruption; and P. Ignatio, in his account of the same eruption, says, that he and his companions picked up many shells likewise at that time upon the mountain: this circumstance would induce one to believe, that the water thrown out of Vesuvius, during that formidable eruption, came from the sea.
