Spectra and Atoms to be Bohr's Topic

Professor Niels Bohr, the celebrated physicist from the University of Copenhagen is to give this afternoon in the lecture room of the Jefferson Physical Laboratory the first of two lectures on the theory of spectra and atomic constitution.

Professor Bohr is an international authority on spectra and radio activity and has done valuable work in proving the electron theory of the composition.

Professor Bohr will give a second lecture on the same subject tomorrow
