D. McFarlan Moore: Mr. Jones has given us a demonstration which proves the fallacy of attempting to illuminate any interior without giving very careful attention to the matter of shadows. The problems of interior illumination are generally duplex, that is, attention must be given to daytime illumination and night time illumination. There are some instances, however, when it is not desired to produce at night time the same effect as in daytime.
