The Fisherman and the Merman
Of mermen and merwomen many strange stories are told in the Shetland Isles. Beneath the depths of the ocean, according to these stories, an atmosphere exists adapted to the respiratory organs of certain beings, resembling, in form, the human race, possessed of surpassing beauty, of limited supernatural powers, and liable to the incident of death. They dwell in a wide territory of the globe, far below the region of fishes, over which the sea, like the cloudy canopy of our sky, loftily rolls, and they possess habitations constructed of the pearl and coral productions of the ocean. Having lungs not adapted to a watery medium, but to the nature of atmospheric air, it would be impossible for them to pass through the volume of waters that intervenes between the submarine and supramarine world, if it were not for the extraordinary power they inherit of entering the skin of some animal capable of existing in the sea, which they are enabled to occupy by a sort of demoniacal possession. One shape they put on, is that of an animal human above the waist, yet terminating below in the tail and fins of a fish, but the most favourite form is that of the larger seal or Haaf-fish; for, in possessing an amphibious nature, they are enabled not only to exist in the ocean, but to land on some rock, where they frequently lighten themselves of their sea-dress, resume their proper shape, and with much curiosity examine the nature of the upper world belonging to the human race. Unfortunately, however, each merman or merwoman possesses but one skin, enabling the individual to ascend the seas, and if, on visiting the abode of man, the garb be lost, the hapless being must unavoidably become an inhabitant of the earth.
