Whilst Professor OWEN was advancing this conjecture, another comparative anatomist, from the examination of another portion of the structure of the elephant, was led to a somewhat similar conclusion. Dr. HARRISON of Dublin had, in 1847, an opportunity of dissecting the body of an elephant which had suddenly died; and in the course of his examination of the thoracic viscera, he observed that an unusually close connection existed between the trachea and oesophagus, which he found to depend on a muscle unnoticed by any previous anatomist, connecting the back of the former with the forepart of the latter, along which the fibres descend and can be distinctly traced to the cardiac orifice of the stomach. Imperfectly acquainted with the habits and functions of the elephant in a state of nature, Dr. HARRISON found it difficult to pronounce as to the use of this very peculiar structure; but looking to the intimate connection between the mechanism concerned in the functions of respiration and deglutition, and seeing that the proboscis served in a double capacity as an instrument of voice and an organ for the prehension of food, he ventured (apparently without adverting to the abnormal form of the stomach) to express the opinion that this muscle, viewing its attachment to the trachea, might either have some influence in raising the diaphragm, and thereby assisting in expiration, "or that it might raise the cardiac orifice of the stomach, and so aid this organ to regurgitate a portion of its contents into the oesophagus."[1271]
Dr. HARRISON, on the reflection that "we have no satisfactory evidence that the animal ever ruminates," thought it useless to speculate on the latter supposition as to the action of the newly discovered muscle, and rather inclined to the surmise that it was designed to assist the elephant in producing the remarkable sound through his proboscis known as "trumpeting;" but there is little room to doubt that of the two the rejected hypothesis was the more correct one. I have elsewhere described the occurrence to which I was myself a witness[1272], of elephants inserting their proboscis in their mouths, and withdrawing gallons of water, which could only have been contained in the receptacle figured by CAMPER and HOME, and of which the true uses were discerned by the clear intellect of Professor OWEN. I was not, till very recently, aware that a similar observation as to the remarkable habit of the elephant, had been made by the author of the Ayeen Akbery, in his account of the Feel Kaneh, or elephant stables of the Emperor Akbar, in which he says, "an elephant frequently with his trunk takes water out of his stomach and sprinkles himself with it, and it is not in the least offensive."[1281] FORBES, in his Oriental Memoirs, quotes this passage of the Ayeen Akbery, but without a remark; nor does any European writer with whose works I am acquainted appear to have been cognisant of the peculiarity in question.
It is to be hoped that Professor OWEN'S dissection of the young elephant, recently arrived, may serve to decide this highly interesting point.[1282] Should scientific investigation hereafter more clearly establish the fact that, in this particular, the structure of the elephant is assimilated to that of the llama and the camel, it will be regarded as more than a common coincidence, that an apparatus, so unique in its purpose and action, should thus have been conferred by the Creator on the three animals which in sultry climates are, by this arrangement, enabled to traverse arid regions in the service of man.[1291] To show this peculiar organization where it attains its fullest development, I have given a sketch of the water-cells, in the stomach of the camel on the preceding page.
The food of the elephant is so abundant, that in feeding he never appears to be impatient or voracious, but rather to play with the leaves and branches on which he leisurely feeds. In riding by places where a herd has recently halted, I have sometimes seen the bark peeled curiously off the twigs, as though it had been done in mere dalliance. In the same way in eating grass the elephant selects a tussac which he draws from the ground by a dexterous twist of his trunk, and nothing can be more graceful than the ease with which, before conveying it to his mouth, he beats the earth from its roots by striking it gently upon his fore-leg. A coco-nut he first rolls under foot, to detach the strong outer bark, then stripping off with his trunk the thick layer of fibre within, he places the shell in his mouth, and swallows with evident relish the fresh liquid which flows as he crushes it between his grinders.
The natives of the peninsula of Jaffna always look for the periodical appearance of the elephants, at the precise
time when the fruit of the palmyra palm begins to fall to the ground from ripeness. In like manner in the eastern provinces where the custom prevails of cultivating what is called chena land (by clearing a patch of forest for the purpose of raising a single crop, after which the ground is abandoned, and reverts to jungle again), although a single elephant may not have been seen in the neighbourhood during the early stages of the process, the Moormen, who are the cultivators of this class, will predict their appearance with almost unerring confidence so soon as the grains shall have begun to ripen; and although the crop comes to maturity at different periods in different districts, herds are certain to be seen at each in succession, as soon as it is ready to be cut. In these well-timed excursions, they resemble the bison of North America, which, by a similarly mysterious instinct, finds its way to portions of the distant prairies, where accidental fires have been followed by a growth of tender grass. Although the fences around these chenas are little more than lines of reeds loosely fastened together, they are sufficient, with the presence of a single watcher, to prevent the entrance of the elephants, who wait patiently till the rice and coracan have been removed, and the watcher withdrawn; and, then finding gaps in the fence, they may be seen gleaning among the leavings and the stubble; and they take their departure when these are exhausted, apparently in the direction of some other chena, which they have ascertained to be about to be cut.
