Of the 72 who died in one year's servitude, 35 expired within the first six months of their captivity. During training, many elephants die in the unaccountable manner already referred to, of what the natives designate a broken heart.
On being first subjected to work, the elephant is liable to severe and often fatal swellings of the jaws and abdomen.[2271]

Of the 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.[2281] 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.
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[2282]; and hence, by inference, that they would be devoid of sensation.
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 ivory. But if, as there seems no reason to doubt, these delicate nervous processes traverse the tusk by means of the numerous tubes already described, if attacked by caries the pain occasioned to the elephant would be excruciating.
As to maintaining a stud of elephants for the purposes to which they are now assigned in Ceylon, there may be a question on the score of prudence and economy. In the rude and unopened parts of the country, where rivers are to be forded, and forests are only traversed by jungle paths, their labour is of value, in certain contingencies, in the conveyance of stores, and in the earlier operations for the construction of fords and rough bridges of timber. But in more highly civilised districts, and wherever macadamised roads admit of the employment of horses and oxen for draught, I apprehend that the services of elephants might, with advantage, be gradually reduced, if not altogether dispensed with.
