OF the many features which will hereafter stamp the nineteenth century as "Centuria Mirabilissima," not the least will be the vast number of animals and birds introduced into Europe, and the great stride made in our knowledge of Natural History during its progress. The precise date of the extinction of a genus or a species has interest; the dodo of the Mauritius and the dinornis of New Zealand have disappeared within the historical period, and there is no reason to suppose that such gaps have been, or will be, filled up by new creations. Second only in interest to the occurrence of these blanks in the list of living inhabitants of the surface of this globe is the record of the introduction of a new race into a part of our planet where it was previously unknown. In such instances the last twenty years have been prolific; the graceful bower-birds and the Tallegalla or mound-raising birds, those wondrous denizens of the Australian wilderness, may now be seen in the Regent's Park for the first time in this hemisphere. For the first time, also, the wart hog of Africa there roots, and the hippopotamus displays his quaint gambols; and that "fairest animal," the giraffe, is now beheld in health and vigor, a naturalized inhabitant of Great Britain.

A giraffe presented by the Pasha of Egypt to the king of England, was conveyed to Malta under the charge of two Arabs, and was from thence forwarded to London in the "Penelope," which arrived on the 11th of August, 1827. She was conveyed to Windsor two days afterward, and was kept in the royal menagerie at the Sandpit-gate. George the Fourth took much interest in this animal, visiting her generally twice or thrice a week, and sometimes twice a day. It would have been better if he had left her to the management of the keepers; but, acting on some vague instructions left by the Arabs, his majesty commanded that she should be fed on milk alone—a most unnatural diet when the animal had attained the age of two years. From this cause, and in consequence of an injury which she had received during her journey from Sennaar to Cairo, the giraffe became so weak as to be unable to stand; a lofty triangle was built, and the animal kept suspended on slings to relieve its limbs from the support of its weight. The apparatus was provided with wheels, and, in order that she might have exercise, it was pushed along by men, her feet just moving and touching the ground. It may well be supposed that such an artificial existence could not be prolonged to any great length of time, and although the giraffe lived between two and three years, and grew eighteen inches in height, she gradually sank and died in the autumn of 1829, to the great regret of the king. Her body was dissected by the sergeant-surgeon, Sir Everard Home, and an account thereof published by him.

Those who frequented the British Museum in the days of Montague-house, shortly before the present building was erected, will remember a hairless stuffed giraffe, which stood at the top of the stairs, mounting sentry, as it were, over the principal door. This miserable skin was interesting, as being the remains of the first entire specimen recorded. Its history was as follows: The late Lady Strathmore sent to the Cape, to collect rare flowers and trees, a botanist of the name of Paterson, who seems to have penetrated a considerable distance into the interior—sufficiently far, at least, to have seen a group of six giraffes. He was so fortunate as to kill one, and brought the skin home for Lady Strathmore; her ladyship presented it to the celebrated John Hunter, and it formed part of the Hunterian collection until a re-arrangement of that museum took place on its removal to the present noble hall in the College of Surgeons. This stuffed specimen, with many others of a similar description, was handed over to the British Museum, and for some years occupied the situation on the landing above mentioned; being regarded as "rubbish," it was destroyed, and the "stuffing" used to expand some other skin. There are now, however, two noble stuffed specimens in the first zoological room of the Museum; one especially remarkable for its dark-brown spots is no less than eighteen feet in height. It is from the southern parts of Africa, and was presented by that veteran zoologist, the Earl of Derby; the other was one of the giraffes brought by M. Thibaut to the Zoological Gardens.

The Zoological Society having made known its wish to possess living specimens of the giraffe, the task of procuring them was undertaken by M. Thibaut, who having had twelve years' experience in African travel, was well qualified for the arduous pursuit.

M. Thibaut quitted Cairo in April, 1834, and after sailing up the Nile as far as Wadi Halfa, the second cataract, took camels and proceeded to Debbat, a province of Dongolah, whence he started for the Desert of Kordofan. Being perfectly acquainted with the locality and on friendly terms with the Arabs, he attached them still more by the desire of profit; all were desirous of accompanying him in pursuit of the giraffes, for up to that time, they had hunted them solely for the sake of the flesh, which they ate, and the skin, of which they made bucklers and sandals. The party proceeded to the southwest of Kordofan, and in August were rewarded by the sight of two beautiful giraffes; a rapid chase of three hours, on horses accustomed to the fatigues of the desert, put them in possession of the largest of these noble animals; unable to take her alive, the Arabs killed her with blows of the sabre, and cutting her to pieces, carried the meat to their head-quarters, which had been established in a wooded situation, an arrangement necessary for their own comfort, and to secure pasturage for their camels. They deferred till the following day the pursuit of the motherless young one, which the Arabs knew they would have no difficulty in again discovering. The Arabs quickly covered the live embers with slices of the meat, which M. Thibaut pronounces to be excellent.

On the following morning the party started at daybreak in search of the young giraffe, of which they had lost sight not far from the camp. The sandy desert is well adapted to afford indications to a hunter, and in a very short time they were on the track of the object of their pursuit: they followed the traces with rapidity and in silence, lest the creature should be alarmed while yet at a distance; but after a laborious chase of several hours through brambles and thorny trees, they at last succeeded in capturing the coveted prize.

It was now necessary to rest for three or four days, in order to render the giraffe sufficiently tame, during which period an Arab constantly held it at the end of a long cord; by degrees it became accustomed to the presence of man, and was induced to take nourishment, but it was found necessary to insert a finger into its mouth to deceive it into the idea that it was with its dam; it then sucked freely. When captured, its age was about nineteen months. Five giraffes were taken by the party, but the cold weather of December, 1834, killed four of them in the desert, on the route to Dongolah; happily that first taken survived, and reached Dongolah in January, 1835, after a sojourn of twenty-two days in the desert. Unwilling to leave with a solitary specimen, M. Thibaut returned to the desert, where he remained three months, crossing it in all directions, and frequently exposed to great hardships and privations; but he was eventually rewarded by obtaining three giraffes, all smaller than the first. A great trial awaited them, as they had to proceed by water the whole distance from Wadi Halfa to Cairo, and thence to Alexandria and Malta, besides the voyage to England. They suffered considerably at sea during a passage of twenty-four days in very tempestuous weather, and on reaching Malta in November, were detained in quarantine twenty-five days more; but despite of all these difficulties, they reached England in safety, and on the 25th of May were conducted to the Gardens. At daybreak, the keepers and several gentlemen of scientific distinction arrived at the Brunswick Wharf, and the animals were handed over to them. The distance to the Gardens was not less than six miles, and some curiosity, not unmingled with anxiety, was felt as to how this would be accomplished. Each giraffe was led between two keepers, by means of long reins attached to the head; the animals walked along at a rapid pace, generally in advance of their conductors, but were perfectly tractable. It being so early in the morning, few persons were about, but the astonishment of those who did behold the unlooked-for procession, was ludicrous in the extreme. As the giraffes stalked by, followed by M. Thibaut and others, in Eastern costume, the worthy policemen and early coffee-sellers stared with amazement, and a few revelers, whose reeling steps proclaimed their dissipation, evidently doubted whether the strange figures they beheld were real flesh and bone, or fictions conjured up by their potations; their gaze of stupid wonder indicating that of the two they inclined to the latter opinion. When the giraffes entered the park, and first caught sight of the green trees, they became excited, and hauled upon the reins, waving the head and neck from side to side, with an occasional caracole and kick out of the hind legs, but M. Thibaut contrived to coax them along with pieces of sugar, of which they were very fond, and he had the satisfaction of depositing his valuable charges, without accident or misadventure, in the sanded paddock prepared for their reception.

The sum agreed on with M. Thibaut was £250 for the first giraffe he obtained, £200 for the second, £150 for the third, and £100 for the fourth, in all £700; but the actual cost to the society amounted to no less than £2386. 3s. 1d., in consequence of the heavy expenses of freight, conveyance, &c.

During the following months of June and July the giraffes excited so much interest, that as much as £120 was sometimes taken at the Gardens in one day, and the receipts reached £600 in the week; they then decreased, and never, until the arrival of the hippopotamus, attained any thing like that sum again. Shortly after their arrival one of the animals struck his head with such force against the brickwork of the house, while rising from the ground, that he injured one of his horns, and probably his skull, as he did not long survive. Guiballah died in October, 1846, and Selim in January, 1849; Zaida, that worthy old matron, is still alive, and may be recognized by her very light color.

An unusual birthday fête was celebrated on the 9th of June, 1839, when Zaida presented the society with the first giraffe ever born in Europe; but alas! it only survived nine days. A spirited water-color sketch was made of the dam and young one when a day old by that able artist, the late Robert Hills; and we recently had an opportunity of seeing this interesting memento. Two years afterward a second was born, and throve vigorously; this fine animal was sent to the Zoological Gardens at Dublin, in 1844. It was rather a ticklish proceeding, but was managed as follows: He was taken very early in the morning to Hungerford market, where a lighter with tackles had been previously arranged. With some dexterity slings were placed under him, and to his great astonishment, he was quickly swung off his feet, and hoisted by a crane into the lighter, and from the lighter, by tackle, on board the deck of the steamer; he had a fine passage, and was welcomed with enthusiasm by the warm-hearted Hibernians, and is now one of the chief ornaments of the Dublin Gardens. Another remarkably fine male, named Abbas Pasha, was born in February, 1849, and is thriving in great vigor in the Gardens at Antwerp.
