Abstract
IN letters recently published in NATURE (Mar. 17, p. 421; May 5, p. 710) Mr. R. W. Gray records the interesting fact that whales dying ‘at a depth’ invariably sink, while those (of certain species) which die at the surface always remain floating. He suggests that the failure to rise after death may be due to the escape of air from the lungs, and in his second letter he attributes this to the water-pressure, which at a certain depth becomes sufficient to overcome the resistance of the valves of the blow-holes.
