Captain Hutton tells us that "this bird breeds in the cliffs of Prince Edward's Island and Kerguelen's Land, but the nests can be got at occasionally. The young are at first covered with a beautiful, long, light grey down; when fledged they are dark brown, mottled with white. When a person approaches the nest, the old birds keep a short distance away, while the young ones squirt a horribly-smelling oil out of their mouths to the distance of six or eight feet. It is very voracious, hovering over the sealers when engaged cutting up a seal, and devouring the carcase the moment it is left, which the Albatross never does. It sometimes chases the smaller species, but whether or not it can catch birds possessed apparently of powers of flight superior to its own is doubtful; but supposing one is killed, that it feeds only upon its heart and liver, I can never believe, yet it is said to do so in the works of many ornithologists." [Illustration: THE FULMAR PETREL (_Procellaria glacialis_).] THE FULMAR PETREL. The FULMAR PETREL (_Procellaria glacialis_) is principally white, light silvery grey upon the under side, and blueish grey upon the mantle. The primary quills are black, the eye is brown, the beak along the culmen pale horn-yellow, at its base greyish green. The foot is yellow, with a shade of blue. In young birds the plumage on the under side of the body is slightly blueish. The length of this species is eighteen or nineteen inches, its breadth forty-one to forty-three inches, the length of its wings twelve to thirteen inches, length of tail four inches and two-thirds.
