THE MALAYAN RUSA-DEER.
The horns, which form the most distinguishing character of the genus, are perfectly solid throughout their whole extent. Their form varies very considerably in the different races; but they are constantly uniform in the same species, unless accidentally or artificially perverted from their natural growth. In some they are simple at the base and terminate in a broad and palmate expansion, which is variously lobed and divided; in others they are more or less branched, giving off antlers in different directions; and in some few they are short and nearly simple. They fall off and are renewed annually in all the species which inhabit the northern and temperate regions of the earth, and in those in which they attain any considerable size; but Sir T. Stamford Raffles was of opinion, and his opinion has been in some measure confirmed by the observations of Major C. Hamilton Smith, that several of the tropical species with small and nearly simple horns are exempted from this general law. The horns are smaller and less developed in the young than in the full grown and adult animal, and diminish again in size, and frequently become irregular, as he advances in age. In one species alone, the Rein-Deer of the North, the female wears the same palmy honours with the male; but they do not in her reach the same enormous extent.
Of the characters of most of the institutions which we have noticed the Tower Menagerie has at various times partaken in a greater or less degree. Originally intended merely for the safe-keeping of those ferocious beasts, which were until within the last century considered as appertaining exclusively to the royal prerogative, it has occasionally been converted into a theatre for their contests, and has terminated by adapting itself to the present condition of society as a source of rational amusement and a school of zoological science.
