To quickly assess the difficulty of the text, read a short excerpt:
The first division is large and rounded like a great bag, some 99 inches on the greater curvature; the second is more cyUndrical, opening from the upper part of the first division, and is about 97 inches long. Its walls are slightly thicker and in both are plicated. The third and fourth divisions are shorter and cylindrical. Immediately below the last cavity of the stomach the hepatic duct enters. The total length of the small intestine of Murie's specimen was 248 feet or four times the length ...of the whale. The large intestine measured about 40 feet. There is no caecum. A remarkable adaptation to aquatic life is found in the Cetacea whereby a projection of the epiglottis extends upward from the pharynx or throat £is a tube into the posterior narial opening of the skull, so that a continuous passage is formed from the blowholes to the lungs, and thus eflfectually prevents the entrance of water into the lungs from the mouth. A similar structure occurs in the Ungulates, so that, as in the horse, they cannot breathe through the mouth.
