These results were confirmed in work on the dogfish, (Mustelus), by Sheldon (1911) and on the swellfish, (Spheroides), by Copeland (1912). Sheldon closed the nares of the dogfish with cotton plugs and, in 1914, I showed that when only one nostril is thus plugged, the fishes turn persistently to- ward the side of the open nostril. Such responses indicate that in the seeking of food under normal con- ditions, dogfishes, and probably other fishes as well, turn.
