"The Ostrich is the largest of all living birds, standing from six to eight feet in height, and has been known from remote antiquity; Xenophon mentions it in the "Anabasis" as found in the plains of Artemisia, and there are frequent references to it in later Roman literature. Hunters report that the flesh is palatable. The ostrich is hunted and bred for the sake of the quill feathers of the wings and tail.The Ostrich is a vegetable feeder, but swallows stones, bits of iron, and other hard substances to aid the gizzard in its functions. On ostrich farms newly hatched birds have been observed to pick up little stones before taking any food. The wings are useless for flight, but of so much assistance in running that the bird can outstrip the fleetest horse."—(Charles Leonard-Stuart, 1911)

"The Penguins are aquatic birds confined to the high S. latitudes or both hemispheres, where they congregate in large flocks. The body is generally elliptical; neck of moderate length; bill moderately long, straight, compressed; tail short. They have no quills in their wings, which are as rigid as the flippers of a cetacean, and utterly useless for flight, though they move freely at the shoulder joint, forming most efficient paddles, and are usually worked alternately with a rotatory motion. In standing, the penguin preserves an upright position, generally resting on the tarsus, which is widened like the foot of a quadruped; but in progressing this is kept nearly vertical, and the weight supported on the toes alone."—(Charles Leonard-Stuart, 1911)
