To furnish every possible link in the grand procession of organized life, is the aim of the science of zoology. Its professors have explored the wilds of Africa, and have penetrated far into the interior of South America; have endured the last extremities of hunger and thirst to catch some curious humming-bird; have been consumed by fevers to the very socket of life, in order to pin an unknown beetle, or to procure some rare and gorgeous-coloured fly. The passion for this science seems to have long dwelt in the English race: our love of field-sports, and keen relish of rural life, coupled with a habit of minute observation, have all had a tendency to foster an acquaintance with the beasts of the field and the fowls of the air, and scarcely a village but boasts of some follower of White or Waterton. This taste we carry with us to our vast colonial possessions, and to that chain of military posts whose morning guns echo round the world. With such splendid opportunities for observing and collecting animals, we have succeeded in gathering together a menagerie which is by far the first in existence, and which includes typical forms of most living things--from the chimpanzee, in whose face and structure we trace the last step but one of the highest form of mammal, to the zoophyte, which shakes hands with the vegetable world. Ancient Rome, it is true, in her degenerate days, witnessed vaster collections of animals, and saw hippopotami, ostriches, and giraffes, together with the fiercer carnivora, turned by hundreds into the arena; but how different the spirit with which they were collected! With the debased and profligate Roman emperors the only object of these bloody shows was to gratify the brutal appetite of their people for slaughter; with us the intention is to display the varying wonders of creation.
