KEEP UP HUNT FOR SUBSTITUTE TO RADIUM RAY Report on Experiments Is Made at Session of Physical Society. Rft Sricnrr Srr< \rr BERKELEY, Cal , Dor 20 —Manmade transmutation of the elements ' and artificial radioactivity by high 1 energy atomic taomDardment were reported to the meeting of the American Physical Society here today from the laboratories of the host institution, the University of California. Eight different chemical elements, ranging from sodium and chlorine, found in common table salt, to rare platinum and deadly arsenic, give off piercing radiation like that from radium, according to papers presented by investigators working in the laboratory of Prof. E v O. Lawrence. f Tool of accomplishment fog the many researches was the giaht 85ton cyclotron magnetic accelerator apparatus, invented and developed by Prof. Lawrence. The investigators not only have the immediate purpose of telling how atoms are put together but hold the hope of realizing some cheap yet effective substitute for costly radium in the treatment of cancer and its allied diseases. New Reports Hopeful Gamma radiation, the type of rays used in cancer hospitals, was reported by J. R. Richardson as being given off from sodium, chlorine and aluminum with energies as high as 3,400,000 volts Platinum became radioactive under deuteron bombardment, declared J. N. Cork and Prof. Laurence, and yielded radiation having energy of 4.500.000 volts. H. G- Paxton described experiments with radioactive phosphorus having a half life period of over 50 hours. Comparable experiments with zinc discussed by Dr. J. J. Livingood yielded artificial radioactivity having a half life of as much as 100 hours. Most artificially radioactive elements retain their activity for only a few minutes at the most. The search, thinking of possible biological and medical applications, has been to find substances which would

PAINTING A BARN?

'rlWr

You’d never suspect, just watching Dorothy Lee going through her lipstick ritual, that she covers 9.68 square feet of lips in a year and that she and the other 2874 co-eds at the University of Wisconsin use enough lipstick annually to paint four good-sized barns. But that’s what the test shows. The chart below shows that the average lip area is .83 square inch. With the painting process repeated 32 times a week, the annual territory coverage reaches the 9.68 average average for each co-ed.

be active for longer periods. Radium, by comparison, has a half life of 1600 years and. although costly, wears out, by distintegration, very slowly. The new reports on artificial activity lasting as long as five days are encouraging..

PURDUE OFFERS SPECIAL STUDY IN VEGETABLES Short Course Is Designed to Benefit Young Growers. j Timm Sped'.l LAFAYETTE, Ind., Dec. 20.—A special short course in vegetable crops is to be given at Purdue University Jan. 27 to Feb. 1, it was announced here today by the Purdue University horticultural department. Designed primarily for young growers with limited or no experience, rather than for commercial ! growers, the course is to touch on | all problems of vegetable cultiva- | tion. Production and marketing of crops is to be discussed by speak- ; ers from the Purdue staff. Such j topics as the general situation and i importance o f horticulaural products in the Hoosier State are to be discussed, along with the technical phases of producing and marketing vegetables. Subjects of Talks Dr. J. H. MacGillivray is to explain how plants grow; E. C. Stair, practical points on plant growing; F. : C. Gaylord, grading and marketing; G. P. Walker, fertilizers for vegetables, and Dr. R. W. Samson, plant | diseases. A talk on insects and how to | identitfy and control them is to be given by Prof. J. J. Davis; R. R. | Fraser is to speak on soil and plant | testing methods: J. A. MacClintock and Mr. Stair, dusting and spraying materials and how to apply them, and W. W. Ward, potatoes for Indiana. Along with these lectures are to be demonstrations and actual class work in the tasks with which every 7 successful vegetable grower must be familiar. Further information about the course may be obtained from any county agricultural agent or the horticultural department of Purdue University here. mm check* mm colds ODD FEVER mW day Ll sa , i! > vS-m> , sb TS headaches DROPS In 30 minutes
