design of large auditoriums, where, because of thelarge volume of the room, the loudness of speech or music reachingthe auditors is greatly diminished. 2. Reverberation probably is the most important factor in determiningthe acoustics of auditoriums. This, of course, is the conclusionestablished by the investigations of W. C. Sabine and others, andis supported by the experience of the past twenty-five years. Thepresent investigation shows quantitatively the harmful effect ofreverberation upon speech reception. 3. The time of reverberation in small rooms, intended for speakingpurposes only, should be reduced to less than 1.0 second for thebest hearing conditions. 4. Further tests are necessary to establish the optimum time of rever-beration for auditoriums intended primarily for speaking purposes.These preliminary tests show that the optimum time is quite small,perhaps even smaller than is attained or planned in current practice.

Next to a hospital a building designed solely forI)hysicians and dentists is to be classed in such a group. It must be pro-vided with such installations of machinery as will guarantee uninter-rupted service of the requisites to modern surgery, pure water supply,electricity supply, and compressed air supply. These must not fail sincethe moment of their failure conceivably might be the crucial moment ina delicate operation in which they might play an all important part. The Medico-Dental Building, located at Post and Mason streets, SanFrancisco, demanded just this type of mechanical service, a ser
