There are in India, as well as in Africa, certain old bull elephants that lead a solitary life, and that are scarcely ever seen in company with the herds. These bachelors are usually of a morose and fierce disposition, and when one of them is captured it requires all the skill of the hunters to keep clear of danger. These wild bulls are larger and stronger than the common kind, and so untamable in their ferocity that even when captured no use can be made of them, since they will die rather than submit to being trained. They are called Goondahs by the people of Hindostau, and by English hunters Rogues or Rovers. The African elephant next merits attention. There is no difficulty in distinguishing this species from any of the Indian varieties. The immensely large ears constitute a marked characteristic of the former, which at once becomes recognisable. Other points of difference are the greater convexity of the forehead or skull and the larger size of the tusks; though this last point of distinction is not always to be depended upon, since there are Indian elephants with tusks of similar dimensions. Generally, however, the African elephants have the largest "ivories." In point of bulk the Asiatic species has been considered superior; but this belief may not be correct. Certain circumstances should be taken into account. The Asiatic elephant is living in a domesticated state, and this may have produced a greater size, as it does in the case of most other quadrupeds. Another circumstance: the African elephants of our collections have been mostly obtained from the Cape, or the regions contiguous to it. But it is now known that in the countries nearer to the equator there exists a much larger kind, that appears to be quite as bulky as any of the Asiatic varieties. The height of the elephant has been much exaggerated by travellers--some having been described as measuring eighteen feet from the foot to the top of the shoulder! An authority on this subject, who measured the largest he could meet with in different parts of India, found none that stood over twelve feet, and this appears to be the actual height of the very biggest of elephants. The African elephants have not been tamed--at least not in modern times; but it is certain that the elephants used by the Carthaginians in their wars with the Romans were of this species; and also that African elephants were the species exhibited by Caesar and Pompey in the Roman arena.
