. Diversions of a naturalist. Natural history. 286 DIVERSIONS OF A NATURALIST in which the teeth are socketed they must be big enough to occupy a length of two inches and two-fifths (con- sult Fig. 25 and its explanation). Dr. Smith Wood- ward did not hesitate, in view of the shape of the jaw so closely like that of a chimpanzee, to postulate the. 7— B Fig. 25.—The Piltdown Jaw (shaded) and the Heidelberg Jaw (outline only) super-imposed and compared by placing the first and second molar teeth (1 and 2) of the two specimens in exact coincidence on the horizontal line A, B. The linear dimensions of the drawings are reduced to two- thirds of those of the specimens. It is obvious that when the front bony part of the Piltdown jaw is completed with an outline like that of the Heidelberg and Neander jaws, as shown by the dotted line m, the space between its molars and the sockets of its front teeth cannot be filled by teeth of the normal human dimensions, as it is in the Heidelberg jaw. As the figure shows, they would stop short half an inch from the front of the jaw. Hence Dr. Smith Woodward inferred that larger teeth like those of a chimpanzee were present in this region in the Piltdown jaw (Eoanthropus). former existence in it of big front teeth—canines and incisors—like those of a chimpanzee, and unlike those of man, although there was no trace of them left in the specimen. He restored the jaw, giving it very much the shape and the teeth of a chimpanzee's jaw (Fig. 23, B). That this was a correct interpretation was proved a year.
