MAN IS BELIEVED MILLION YEARS
 MORE ANCIENT
Scientists Have Found /, Method to Figure Their Existence as Way Be- y0nd What Was Be- lieyed
By BATES RANEY

(United Press Stan Corrcspondent) New Haven, Conn, Nov 16.- (UP)-Scientist have found way to figure that prehistoric man is a million years older than gen. erally believed.
 Their method for so figuring was explained here to-day by Henry F. Osborne, director emeritus of the American Museum of Naural His tory. He spoke at the National Academy of Sciences in session at Yale.
 An entirely new conception of evolution Is envisaged in the method he explained. which calls for determining the age of an elephant by means of the enamel Holdings on their grinding teeth. Osborn's theory, the result of lifetime of research, introduces a new ganometric method of sub dividing plio-pleistocene time, 60,- 900 to 100000 years ago, and de- termines the age of human relics by the age of the fossil elephants teeth found with them.
 Osborn opened the three-day fall meeting of the academy in which a score of internationally known scientists are to present papers ranging from the Arizona expedi- ton to study meteors. to the pre- historic sabre-tooth cats of Rancho La Brea, and the latest experiments in radio broadcasting. The ascent of man up the lad der of culture from the stone age. the oldest known period Of pre- historic mans culture. was de- scribed by George Grant Mac- Curdy, research associate in pre- historic archaeology at Yale un!- versity, In a discussion of the use of rock crystal by paleolithic man. He revealed that seven perfect rock crystal tools used by prehis- toric man recently have come to the American School of Pre-His- toric Research from Europe. The examples of complete rock crystal tools of the paleolithic age all came from three adjoining depart ments in southern France, he said, which led him to believe that single center somewhere near the hea dquarters of the Vezere river might have been the source of sup ply for the paleolithic home sites in that part of France.
 They attested the growing oul- ture of the old stone men. Halr a million years ago, he pointed out.
 These individuals, short. husky types with bushy hair and pro- truding jaws roamed France ha!f a million years after the true hu- man first appeared, by Dr Osborn's new standard.
 these uncouth, uncivilized humans was made by MacCurdy in pointing out that even when the rock crys- tals were too small to be clipped into perfect tools they were often picked up and carried by the old stone men to their camp sites as ornaments on account of their att tractive colors.
 One of the tools he cited was a combination scraper and point or transparent crystal just tinged with yellow. It probably was used as u building instrument.
 The members of the academy and their guests were welcomed 10 Yale university by President James Rowland Angell. He called their attention to books illustrating the history of science now on exhibit at the Yale library covering every branch of science represented by the academy.
 The first Latin text of hippo crates is shown with later medical exits, notably one of Galen who was for many years the private physician of Marcus Aureiius.
 Dr John Campbell Merriam. president of the Carnegie Institu- ton of Washington. is scheduled tomorrow to discuss "A Climax in Evolution" in which the pre-his- toric saber-toothed cats are fea- tured.
 His lecture will be based upon the fossil remains found in asphalt deposits near Los Angeles, dating ately preceding the present one.
