First of the scheduled radio broadcasts of classroom lectures will take place tomorrow afternoon at 4:30 o'clock, with an address on "Dante" by George B. Weston, associte professor of Romance Languages. This inaugurates a pioneer experiment in the international broadcasting of regular University lectures.

The broadcast tomorrow will be on a wave-length of 11.79 megacycles, through station W1XAL, of Boston, a non-commercial station devoted entirely to educational programs, an financed by private donations and by a grant from the Rockefeller Foundation.

The University, in cooperation with W1XAL, plans to broadcast a comprehensive schedule of activities this spring, including musical concerts, church services, and lectures in the fields of literature, music, philosophy, government, economics, history, and some of the sciences. If the experiment is successful, the radio transmissions will be incorporated next fall as a regular part of the University's program.

Tomorrow's lecture will be broadcast by Professor Weston from Emerson Hall, where he will be addressing students concentrating in ancient and modern languages. This is one of a series of lectures on the world's great authors which are being given for students in this field on Wednesday afternoons at 4:30 o'clock.

The remaining lectures of the series, following the one on on Dante, will include "Goethe," February 24, by John A. Walz, professor of German Language and Literature; "Chaucer," March 3, by Fred N. Robinson, Gurney. Professor of English Literature; and Austotle," March 10, by William C. Greene, associate professor of Greek and Latin.

None of the lectures given in the radio series will be especially adapted for broadcasting, but will present the teachers just as they are heard by the students in class. Lectures given in forenoon classes will not be put on the air immediately, it is planned, but will be recorded and transmitted later at a time more convenient for most listeners.

The first broadcast of services from the Memorial Church will take place at 11 o'clock Sunday, February 28, on 15.25 megacycles.

Announcement of further broadcasts will be made later. Station W1XAL operates at various frequencies, 6.04, 11.79, 15.25, or 21.46 magecycles, depending upon the day and the hour
