As we have already stated, living examples of the Eland were received in Holland from the Cape as long ago as about 1783, when they were described by Vosmaer and others as being in the menagerie of the Prince of Orange. In England the first examples of this species of which we can find any record were those which constituted the herd in the celebrated menagerie of Edward, 13th Earl of Derby, President of the Zoological Society of London. There is, unfortunately, little information available as to the origin and history of this celebrated herd, but from some notes published by Lord Derby in the first volume of the ‘Gleanings,’ we learn that the first specimens received were obtained for him by Mr. Burke from the Cape in November 1842, and consisted of two males and a female. The female first bred in August 1843, and produced young in 1844, 1845, and 1846, at which date Lord Derby remarked that he had in his possession four males and two females of this Antelope. At the dispersal of the Derby Menagerie by auction in October 1851 the Knowsley herd consisted of two males and three females. These passed into the Gardens of the Zoological Society of London, having been selected out of the whole stock by the Council of the Society in virtue of a bequest by Lord Derby to that Society of any group of animals in his collection that they might prefer. The original stock of the Zoological Society’s herd of Elands consisted, therefore, of these five animals received by the Society in December 1851. Of these an old female had been born at Knowsley in 1846, and the other individuals, two males and two females, had been imported by Lord Derby in 1850. These animals throve well in their new quarters and began to increase rapidly. As will be seen by the list given in Wolf and Sclater’s ‘Zoological Sketches’ (vol. i.), two calves were born in 1853, three in 1854, four in 1855, and four in 1856. The first additions made to the original stock were a female presented by the late Sir George Grey in April 1859, and a male received in exchange from Viscount Hill in November of the same year. Since the date of its first institution, the Zoological Society’s herd of Elands has never failed, although occasionally reduced to somewhat small dimensions. Nearly every year one or more Eland-calves have been born in the Gardens, and care has been taken to lose no opportunity of introducing fresh blood whenever the occasion has offered. At the present moment, however, we regret to say, in consequence of the great difficulties now prevailing in obtaining living examples of the larger Antelopes of Africa, the Eland is represented in the Society’s Antelope-House by only two specimens, namely, a male, about six years old, bred in the Jardin d’Acclimatation of Paris, and received on October 12, 1898, and a young female, purchased of Herr Reiche, of Alfeld, in April 1899. The latter is more rufous in colouring and shows slight traces of stripes,
