are quite surprising in proportion to the bulk of the bird. The Apteryx is about as big as a turkey, standing two feet in height, but its egg measures four inches ten lines by three inches two lines in the respective diameters. The egg of the Dinornis giganteus, to bear the same ratio to the bird as this, would be of the incredible length of two feet and a half, by a breadth of one and three quarters! Possibly this specimen, though indubitably the egg of one of this great family of extinct birds, may after all be that of one of the subordinate species.
But about the same time as Mr. Mantell's discovery, one of equal interest was made in Madagascar. The master of a French ship obtained, in 1850, from natives of the island, three eggs, of far greater size, and fragments of the leg-bones of an immense bird. These, on their arrival at Paris, formed the subjects of valuable investigations by M. Isidore Geoffroy St. Hilaire[16] and Professor Owen.[17]
The native statement was, that one of the eggs had been found entire in the bed of a torrent, among the debris of a land-slip; that a second egg, with some fragments of bone, was subsequently found in a formation which is stated to be alluvial; a third egg, which the natives had perforated at one end, and used as a vessel, was also found. This last egg was broken in the carriage, the other two arrived in Europe entire.
These two, though nearly alike in size, differed considerably in their relative proportions and shape, the one being shorter and thicker, with more equal ends than the other. The following table shews the dimensions of both compared with those of an ostrich's egg:—
| Ovoid egg. | Ellipsoid egg. | Ostrich egg. | |||||||||
| ft. | in. | li. | ft. | in. | li. | ft. | in. | li. | |||
| Longer circumference | 2 | 10 | 9 | 2 | 9 | 6 | 1 | 6 | 0 | ||
| Shorter circumference | 2 | 4 | 3 | 2 | 5 | 6 | 1 | 4 | 6 | ||
| Extreme length | 1 | 0 | 8 | 1 | 0 | 5 | 0 | 6 | 4 | ||
M. Geoffroy St. Hilaire estimates the larger of the two to contain 10⅛ quarts, or the contents of nearly six eggs of the Ostrich, or sixteen of the Cassowary, or a hundred and forty-eight of the Hen, or fifty thousand of the Humming bird.[18]
The fragments of bone indicated a bird of the same natural affinities as the New Zealand colossi, and of dimensions not widely remote from theirs. Professor Owen thinks that it did not exceed in height or size Dinornis giganteus, and that there is a probability that it was slightly smaller. The Madagascar bird has been named Æpyornis maximus.
The fragments of the egg of the New Zealand bird (still uncertain as to the species to which it is to be referred) shew that the shell was absolutely thinner, and therefore relatively much thinner than that of the Ostrich's egg; the air-pores, too, have a different form, being linear, instead of round, and the surface is smoother. In these qualities, the New Zealand egg resembles that of the Apteryx; in the thickness and roughness of the egg of Æpyornis there is more similarity to those of the Ostrich and Cassowary. The colour of the Madagascar egg is a dull greyish yellow; but it is possible that this may be derived from the soil in which it has long been imbedded. The fragments of the New Zealand egg are white, like the eggs of the Apteryx and Ostrich: those of the Emu and Cassowary are light green.
The willing fancy suggests the possibility that, in an island of such immensity as Madagascar, possessing lofty mountain-ranges, covered with the most magnificent forests, where civilised man has only yet touched one or two spots on the seaward borders, but where these slight explorations have educed so many wondrous animals, so many strange forms of vegetable life, the noble Æpyornis may yet be stalking with giant stride along the fern-fringed hill-sides, or through the steaming thickets; though in the more contracted area of New Zealand its equally ponderous cousins, the Dinornis and the Palapteryx, may have sunk beneath the persevering persecutions of man.
Yet another item of evidence bearing on the recent if not present existence of these great fowls has recently come to light:—the most interesting discovery that one of the genera whose fossil remains had been found associated with theirs is really extant in New Zealand. I refer to the Notornis.
At a meeting of the Zoological Society of London, held on the 13th November 1850, Dr. Mantell made the following communication relative to this discovery:—
"It was in the course of last year, on the occasion of my son's second visit to the south of the middle island, that he had the good fortune to secure the recent Notornis, which I now submit, having previously placed it in the hands of the eminent ornithologist Mr. Gould, to figure and describe. This bird was taken by some sealers who were pursuing their avocations in Dusky Bay. Perceiving the trail of a large and unknown bird on the snow, with which the ground was then covered, they followed the footprints till they obtained a sight of the Notornis, which their dogs instantly pursued, and, after a long chase, caught alive in the gully of a sound behind Resolution Island. It ran with great speed, and on being captured uttered loud screams, and fought and struggled violently. It was kept alive three or four days on board the schooner, and then killed, and the body roasted and eaten by the crew, each partaking of the dainty, which was declared to be delicious. The beak and legs were of a bright red colour. My son secured the skin, together with very fine specimens of the Kapapo or ground parrot (Strigops), a pair of Huias (Neomorpha), and two species of Kiwikiwi, namely Apteryx Australis, and A. Oweni. The latter very rare bird is now added to the collection of the British Museum."
"Mr. Walter Mantell states, that, according to the native traditions, a large Rail was contemporary with the Moa, and formed a principal article of food among their ancestors. It was known to the North Islanders by the name 'Moho,' and to the South Islanders by that of 'Takahe;' but the bird was considered by both natives and Europeans to have been long since exterminated by the wild cats and dogs; not an individual having been seen or heard of since the arrival of the English colonists. On comparing the head of the bird with the fossil cranium, and mandibles, and the figures and descriptions in the 'Zoological Transactions' (Plate lvi.), my son was at once convinced of their identity. It may not be irrelevant to add, that in the course of Mr. Walter Mantell's journey from Banks's Peninsula along the coast to Otago, he learned from the natives that they believed there still existed in that country the only indigenous terrestrial quadruped, except a species of rat, which there are any reasonable grounds for concluding New Zealand ever possessed. While encamping at Arowenua, in the district of Timaru, the Maoris assured them that about ten miles inland there was a quadruped which they called Káureke, and
