"If I could but wash this corpse in a solution of sulphuric acid," continued my uncle, "I would undertake to remove all the earthy particles, and these resplendent shells, which are incrusted all over this body. But I am without this precious dissolving medium. Nevertheless, such as it is, this body will tell its own history." Here the Professor held up the fossil body, and exhibited it with rare dexterity. No professional showman could have shown more activity. "As on examination you will see," my uncle continued, "it is only about six feet in length, which is a long way from the pretended giants of early days. As to the particular race to which it belonged, it is incontestably Caucasian. It is of the white race, that is, of our own. The skull of this fossil being is a perfect ovoid without any remarkable or prominent development of the cheekbones, and without any projection of the jaw. It presents no indication of the prognathism which modifies the facial angle.[4] Measure the angle for yourselves, and you will find that it is just ninety degrees. But I will advance still farther on the road of inquiry and deduction, and I dare venture to say that this human sample or specimen belongs to the Japhetic family, which spread over the world from India to the uttermost limits of western Europe. There is no occasion, gentlemen, to smile at my remarks." [4] The facial angle is formed by two planes--one more or less vertical which is in a straight line with the forehead and the incisors; the other, horizontal, which passes through the organs of hearing, and the lower nasal bone. Prognathism, in anthropological language, means that particular projection of the jaw which modifies the facial angle. Of course nobody smiled. But the excellent Professor was so accustomed to beaming countenances at his lectures, that he believed he saw all his audience laughing during the delivery of his learned dissertation.
