The eyes of the gorilla are large, dark, and expressive, but there is no trace of white in them. That part of the eye which is white in man is a dark coffee-brown in the gorilla, but becomes lighter as it approaches the base of the optic nerve. The taxidermist or the artist, who often furnishes him with a white spot in the corner of his eye, does violence to the subject; and those who pose the animal with his mouth open like a fly-trap, and his arms raised like a lancer, ought to be banished from good society. It is true that such things lend an aspect of ferocity to the creature, but they are caricatures of the thing they mean to portray. The ears of the gorilla are very small, and lie close to the sides of the head. The model of them is much like the human ear. I shall not pursue the comparison into minute details, but leave that to the specialist, in whose hands it will be treated with more skill and greater scope. As my especial line of research has been in the study of their speech and habits, I shall confine myself to that, but the general comparison I have made is necessary to a better understanding of the subject. CHAPTER XV HABITS OF THE GORILLA A study of the habits of the gorilla in a wild state is attended with much difficulty, but the results that I obtained during a sojourn of one year among them are an ample reward for the efforts made. In a state of captivity the habits of animals are made to conform in a measure to their surroundings, and since those are different many of their habits differ also. Some are foregone, others modified, and new ones acquired, therefore we cannot know with certainty what the animal was in a state of nature. In the social life of the gorilla there are a few things perhaps that differ very much from that of the chimpanzee, but there are some that do in a certain degree. From the native accounts of the modes of life of these two apes, there would appear to be a much greater difference than a systematic study of them reveals; but the native version of things frequently has a germ of truth which may serve as a clue to the facts in the case; and while we cannot rely upon the tales they relate in all details, we can forgive the mendacity and make use of the suggestion they furnish. It is certain that the gorilla is polygamous in habit, and it is probable that he has an incipient idea of government. Within certain limits he has a faint perception of order and justice, if not of right and wrong. I do not mean to ascribe to him the highest attributes of man, or exalt him above the plane to which his faculties assign him; but there are reasons to justify the belief that he occupies a higher social and mental sphere than other animals, except the chimpanzee.
