Abstract
IN the Transactions of the Royal Society of South ability Australia, vol. i., 1926, an interesting contri to slide ahead with no other power than their own bution is made by Prof. F. Wood Jones on the flight of sea-birds. It has long been observed that many sea-birds spend protracted periods, sometimes soaring, sometimes gliding, and at any rate to the novice, apparently without a visible termor of the wing. Their flight appears to be merely an ability to slide ahead with no other power than their own weight and a presumably instantaneous ability to readjust their planes and alter their cant and poise largely by movements of the head.
