Show Fingerprinted Beam Will Probe 11 1 Mysteries on High New Scientific Marvel 1 to Transcend Strato WASHINGTON A A new method of discovering what exists exists exists ex ex- ex- ex in the unexplored upper air beyond the reach of balloons some 20 to 50 miles above the earth has been developed by three Washington n physicists connected with the Carnegie Institutions Institution's institutions institution's department of ot terrestrial magnetism and the United States Department t of ot Agricultures Agriculture's bureau of chemistry and soils Searchlights will be used to shoot light Into the night sky tight light that thatIs I Is fingerprinted by being Interrupted Interrupted interrupted Inter Inter- at a given gl frequency using a tI light chopper so that when It ItIs ItIs itIs Is scattered by the upper air and picked up by large mirrors It can be recognized by hy tuning the observing In ing Instruments ts From what happens to the light In the upper airs air's greatest unknown region will come the answer to some questions that science Is eagerly eagerly eagerly ea ea- ea- ea gerly asking Will Probe Unfamiliar Strata How the thinning airs air's density varies with height some 30 miles above the tile stratosphere In the regions regions re reo re- re gions glons known kno as the ozonosphere will become become be be- and the alto troposphere come known This Is Important basic Information now lacking The research team that has taken tak take en the first steps toward conquest of the region between where the stratosphere leaves off orr and the aurora begins to be born consists of Dr M.
