Abstract
ABOUT a month ago I picked up on Maenporth Beach, near Falmouth, a piece of drift pumice of the size of a large goose's egg. It was rounded, floated heavily, and was just twice the weight of a piece of Krakatao pumice of the same size which had been obtained in the Indian Ocean several months after the eruption. No Cirripedes, Serpulrae, c but in one of its crevices I found a tiny dead coleopterous insect, which I unfortunately lost. From my familiarity with floating pumice in the Western Pacific I at once perceived that this fragment had been a considerable time in the water. After searching the other beaches in the neighbourhood failed to find another piece. Mr. John Murray, to whom I sent the specimen, informs me that he has similarly picked up fragments of pumice on the west coast of Scotland.
