Illustrating his lecture with lantern slides of the latest developments in the field of modern building, Kenneth J. Conant '15, professor of Architecture, will speak this afternoon at 5 o'clock in Robinson Hall Annex on "The Development of Modern Architecture." The lecture is given in connection with the exhibition of models and photographs of new types of architecture assembled by the Museum of Modern Art in New York, which is now being held in Robinson Hall Annex. Professor Conant has made a study of modern architecture in many European countries.

The exhibition of modern architecture has attracted a great deal of attention, since it illustrates the architectural uses of steel and other new structural materials. As a result of the wide-spread comment aroused by the buildings at the Century of Progress Exposition, interest in radically modernistic forms of architecture has brought many outside visitors to the exhibition.

The Fogg Museum also announces that the second of a series of four illustrated lectures on "Medieval Russian Churches" will be given tomorrow at 4.30 o'clock in the Fogg Museum. It is entitled "Novgorod and Oskov."
