Professor W. C. Sabine, A.M. '88, will deliver the ninth of the series of University war lectures in the New Lecture Hall tomorrow evening at 8 o'clock on "Aviation and the War." These lectures are given for the purpose of better acquainting members of the University with conditions and customs in the warring countries. They are not open to the public.

Professor Sabine stated yesterday that his speech "will relate to conditions at the front, and the function of aviation as an offensive weapon, and as an aid to the other branches of the service." The lecture will be illustrated with lantern slides, and will deal to a considerable extent with airplane photography. The speaker will also discuss the part of the airplane in actual fighting.
