Abstract

WITH reference to the communication published in last week's NATURE, on “Strange Noises heard at Sea off Grey Town,” it does not appear necessary to refer these noises to any occult galvanic agency, or magnetic influence in connection with iron ships, although at first sight, and more especially as there is much ferruginous sand in the vicinity, and as the sounds are heard only in iron ships, and not in wood-built, copper-bottomed vessels, there seems ground for such an idea. The solution I would venture to offer is that these noises proceed from “musical fish” or shells.
