(3) _Eoanthropus Dawsoni_: Dec. 18, 1912, is memorable with evolutionary anthropologists as the day on which Charles Dawson announced his discovery of the famous Dawn Man. The period of discovery extended from the years prior to 1911 up to Aug. 30, 1913, when the canine tooth was found by Father Teilhard de Chardin. The locality was Piltdown Common, Sussex, in England. The fragments recovered were an imperfect cranium, part of the mandible, and the above-mentioned canine tooth. The stratified Piltdown gravel, which Dawson assigns to the Lower Pleistocene or Glacial epoch, had been much disturbed by workmen, “who were digging the gravel for small repairs.” (Dawson.) The discoverer first found a fragment of a parietal bone. Then several years later, after the gravels had been considerably rainwashed, he recovered other fragments of the skull. All parts of the skeletal remains are said to have been found within a radius of several yards from the site of the initial discovery. The skull was reconstructed by Dr. A. Smith Woodward and deposited in the British Museum of Natural History at South Kensington. Eoliths were found in the same gravel as the skull. Of the skull, according to Woodward, four parts remain, which, however, were integrated from nine fragments of bone. “The human remains,” he says, “comprise the greater part of a brain-case and one ramus of the mandible, with two lower molars.” Of Woodward’s reconstruction, Keith tells us that “an approach to symmetry and a correct adjustment of parts came only after many experimental reconstructions” (cf. “Antiquity of Man,” p. 364), and he also remarks that, when Woodward undertook to “replace the missing points of the jaws, the incisor and canine teeth, he followed simian rather than human lines.” (_Op. cit._, p. 324.) Here we may be permitted to observe that, even apart from the distorting influence of preconceived theories, this business of reconstruction is a rather dubious procedure. The absence of parts and the inevitable modification introduced by the use of cement employed to make the fragments cohere make accurate reconstruction an impossibility. The fact that Woodward assigned to the _lower_ jaw a tooth which Gerrit Miller of the United States Museum assigns to the _upper_ jaw, may well give pause to those credulous persons, who believe that palæontologists can reliably reconstruct a whole cranium or skeleton from the minutest fragments. Sometimes, apparently, the “experts” are at sea even over so simple a question as the proper allocation of a tooth.
