_Giraffes_: four received in 1836 cost the Society upwards of 2,300_l._, including 1,000_l._ for steamboat passage: the female produced six male fawns here between 1840 and 1851. _Hippopotamus_, a young male (the first living specimen seen in England), received from Egypt in May, 1850, when ten months old, seven feet long, and six and a-half feet in girth; also a female hippopotamus, received 1854. _Humming-birds_: Mr. Gould's matchless collection of 2,000 examples was exhibited here in 1851 and 1852. _Iguanas_, two from Cuba and Carthagena, closely resembling, in everything but size, the fossil Iguanodon. The _Lions_ number generally from eight to ten, including a pair of cubs born in the gardens in 1853. _Orang-utan_ and _Chimpanzee_: the purchase-money of the latter sometimes exceeds 300_l._ The orang "Darby," brought from Borneo in 1851, is the finest yet seen in Europe, very intelligent, and docile as a child. _Parrot-houses_: they sometimes contain from sixty to seventy species. _Rapacious Birds_: so extensive a series of eagles and vultures has never yet been seen at one view. _The Reptile-house_ was fitted up in 1849; the creatures are placed in large plate-glass cases: here are pythons and a rattle-snake, with a young one born here; here is also a case of the tree-frogs of Europe: a yellow snake from Jamaica has produced eight young in the gardens. _Cobra de Capello_, from India: in 1852, a keeper in the gardens was killed by the bite of this serpent. _A large Boa_ in 1850 swallowed a blanket, and disgorged it in thirty-three days. A _one-horned Rhinoceros_, of continental India, was obtained in 1834, when it was about four years old, and weighed 26 cwt.; it died in 1850: it was replaced by a female, about five years old. _Satin Bower-Birds_, from Sydney: a pair have built here a bower, or breeding-place. _Tapir_ of the Old World, from Mount Ophir; the nearest existing form the Paleotherium. _Tigers_: a pair of magnificent specimens, presented by the Guicoway of Baroda in 1851; a pair of clouded tigers, 1854. _The Wapiti Deer_ breeds every year in the Menagerie. The animals in the Gardens, although reduced in number, are more valuable and interesting than when their number was higher. The mission of the Society's head-keeper, to collect rare animals for the Menagerie, has been very profitable. The additional houses from time to time, are very expensive: the new monkey house, fittings, and work cost 4,842_l._; and in 1864, the sum of 6,604_l._ was laid out in permanent additions to the establishment.
