THE OSTRICH. 329 young that we have noticed in other birds, and in animals. The female of a pair in Paris died through swallowing a three-cornered piece of glass which a glazier had dropped into their cage, after which the mate pined away and died in a few weeks. Of their care of their young Captain Cumming says: “J fell in with a troop of about twelve young ostriches, which were not much larger than Guinea-fowls. I was amused to see the mother endeavour to lead us away, exactly like a wild duck, spreading out and drooping her wings, and throwing herself down on the ground before us as if wounded, while the cock bird cunningly led the brood away in an opposite direction.” Professor Thunberg once rode past the place where a hen Ostrich was sitting in her nest; when the bird sprang up, and pursued him, evidently with a view to prevent his noticing her eggs or young. Every time he turned his horse towards her she retreated ten or twelve paces; but as soon as he rode again she pursued him, till he had got to a considerable distance from the place where he had started her.

There are The Emu. several species, known as-the Common Rhea, the Great-billed Rhea, and Darwin’s Rhea, the latter belong- ing to Patagonia. A Common Rhea bred some time ago in the Zoological gardens, when the male bird discharged the duties of incubation. The Cassowary and the Emu belong to Australia. The Cassowary resembles the ostrich in form, but is not so large. It stands about five feet. Like all these birds it is unable to fly, but is very swift of foot. It can kick too, with great violence, as dogs have sometimes found to their cost. The Emu is a very large bird and is said sometimes to exceed six feet in height. Mr. Bennett says:—“ The length of its legs and the muscu- larity of its thighs enable it to run with great swiftness; and as
