The larger gulls grow hopelessly coarse and heavy; the kittiwake is not what it was, something is gone from the bold corsair-like sweeps of the Arctic skua, and even in the seeming-laboured grace of the tern the eye begins to dwell more on the labour and less on the grace. All these birds are bodies: the fulmar petrel more suggests a soul. Something of this it owes to its colouring, which, though approaching to blue above, and of the purest-looking white below, yet has in it that exquisitely smoked or shadowed quality which allows of no glint or gleam, avoids all saliency, and almost seems alien from substance itself. It blends with the air, of which it seems to be a condensation rather than something introduced into it. Yet most lies in the flight.
