That single archaic skull and the commingled bones of the ten bodies and their limbs, all fossilized, scientific diggers recently dug up, a Peiping despatch reported last week. Actual finder was Pei Wenchung, Chinese archeologist, in the party of Dr. Davidson Black, Canadian paleontologist. The find is undoubtedly the most important archeological discovery of the year. It provides one complete and nine nearly complete skeletons of the "Peking man," pithecanthropus erectus, whose vestiges heretofore have consisted of but a skull top, a leg bone, a few teeth...
...paths are slim for electrons going at high speed, broader for slower moving ones. This is a phenomenon noted in Professor Floyd Karker Richtmyer's physics laboratory at Cornell University and announced last week. One of his graduate students, Dr. P. H. Carr of Gaffney, S. C., had noted how pitted the metal targets of X-ray tubes became after long electronic bambardment,* and inferred that flicking light also left its invisible mark. To bring such marks, if existent into sight meant long trials of various reagents on such battered metals. In the end he found that mercury vapor...
...ramshackle bacteriological laboratory of the rich University of Chicago, where often "rats destroy in a night the fruits of six months' work,"* Dr. Isidore Sydney Falk has discovered, the university announced last week, the germ which causes influenza.

It was 11 a. m. in London. 5 a. m. in Chicago. It was a half-hour later when Dr. Falk returned...

Dr. Falk went back to the Rosenau indication. When influenza struck Chicago severely last winter, he and his assistants took cultured smears from every throat they could reach. They slept on their desks to avoid losing time...
