entire, twenty-three were females and eleven males. The ages of those that died could not be accurately stated, owing to the circumstance of their having been captured in corral. Two only were tuskers. Towards keeping the stud in health, nothing has been found so conducive as regularly bathing the elephants, and giving them the opportunity to stand with their feet in water, or in moistened earth. Elephants are said to be afflicted with tooth-ache; their tushes have likewise been found with symptoms of internal perforation by some parasite, and the natives assert that, in their agony, the animals have been known to break them off short.[1] I have never heard of the teeth themselves being so affected, and it is just possible that the operation of shedding the subsequent decay of the milk-tushes, may have in some instances been accompanied by incidents that gave rise to this story. [Footnote 1: See a paper entitled "_Recollections of Ceylon_," in _Fraser's Magazine_ for December, 1860.] At the same time the probabilities are in favour of its being true. CUVIER committed himself to the statement that the tusks of the elephant have no attachments to connect them with the pulp lodged in the cavity at their base, from which the peculiar modification of dentine, known as "ivory," is secreted[1]; and hence, by inference, that they would be devoid of sensation. [Footnote 1: _Annales du Museum_ F. viii. 1805. p. 94, and _Ossemens Fossiles_, quoted by OWEN, in the article on "Teeth," in TODD'S _Cyclop. of Anatomy, &c_., vol. iv. p. 929.] But independently of the fact that ivory in permeated by tubes so fine that at their origin from the pulpy cavity they do not exceed 1/15000th part of an inch in diameter, OWEN had the tusk and pulp of the great elephant which died at the Zoological Gardens in London in 1847 longitudinally divided, and found that, "although the pulp could be easily detached from the inner surface of the cavity, it was not without a certain resistance; and when the edges of the co-adapted pulp and tusk were examined by a strong lens, the filamentary processes from the outer surface of the former could be seen stretching, as they were drawn from the dentinal tubes, before they broke. These filaments are so minute, he adds, that to the naked eye the detached surface of the pulp seems to be entire; and hence CUVIER was deceived into supposing that there was no organic connexion between the pulp and the ivor
