Relation of the Hand to the Eye and the Mouth
You cannot have watched a game of cricket without being struck by the manner in which the hand acts in harmony with the eye. With what almost lightning-like rapidity it is in the exact place to catch the ball; and with what precision the practised cricketer can throw the ball to a great distance. In this, however, he is surpassed by the wonderful skill with which the Indian throws the lasso. Again, it is enough for the sportsman merely to get sight of the bird; he is scarcely conscious of the process by which the hand directs the gun and pulls the trigger at the exact moment. Still more remarkable is the successful aim when taken, as it occasionally is, without bringing the gun to the shoulder.
In estimating the importance of the hand, you must not forget that the mouth is quite dependent upon it for supplies. In most other animals the jaws are prolonged, forwards, from the cranium, and the head is placed in such a position that the mouth becomes an organ of prehension, and is enabled to provide for itself. But, in man, the head is carried so high above the ground, and the jaws are so shortened and compressed beneath the forehead, that the mouth is of little use in obtaining food. Its abilities and duties are restricted to receiving, masticating, and swallowing; and, if it had to rely upon its own efforts for supplies of food, it would, indeed, be in a poor case. When we look at one of the Sphinxes from Egypt, or at one of the stately Bulls from Nineveh, in which wisdom and power are represented by joining a human head to the trunk and limbs of an animal, the question suggests itself, “How is that mouth to be fed?” In the Centaur and Mermaid this difficulty is overcome by adding the hands, as well as the human head, to the trunk and locomotory organs of the horse in the one instance, and the fish in the other; so that monstrosity does not preclude the means of sustentation. Sufficient incongruities, however, still remain to justify the exclamation
“Spectatum admissi risum teneatis amici?”
In the Elephant the mouth is circumstanced, somewhat, as in man; and the office of feeder is performed by the elongated snout or proboscis. This organ, with its finger-like extremity, is so sensitive and mobile as to be able to pick up small bodies—pins or needles—from the ground, and so strong as to pull down large branches of trees, and gather the fruit from them. It is interesting, in connection with the relation of the hand to the will and the intellectual endowments, to remark that this proboscidean substitute, which fulfils so many of the purposes of the hand, is furnished to the “half reasoning” elephant. The natural sagacity and teachableness of this creature, of which such interesting evidence is given in Sir Emerson Tennent’s book on Ceylon, seem to render it quite worthy of the privilege of having an especial organ provided to minister to its will.
