WILL DISCUSS X-RAYS TONIGHT

Radio activity and X-rays will be the subject of a talk tonight at 8 P.M. in the large lecture room of the Jefferson Physical Laboratory by William Duane '93, professor of Bio-Physics at the University. This will be the first of a series of three lectures which the Physics Department is to offer to the Public this spring on topics of every-day Interest.

Professor Duane recently discovered the means of obtaining extremely penetrating X-rays, and has been engaged in research work on this subject for many years. The Harvard Cancer Commission will shortly apply his discovery to the alleviation of cancer.
