The scientific program of the meeting began with a lecture by
Professor Michael I. Pupin, of Columbia University, who
described the work on aerial transmission of speech of which no
authentic account has hitherto been made public. To Professor
Pupin we owe the discovery through mathematical analysis and
experimental work of the telephone relays which recently made
speech by wire between New York City and San Francisco
possible, and we now have an authoritative account of speaking
across the land and sea a quarter way round the earth. One
session of the academy was devoted to four papers of general
interest. Professor Herbert S. Jennings, of the Johns Hopkins
University, described experiments showing evolution in
progress, and Professor John M. Coulter, of the University of
Chicago, discussed the causes of evolution in plants Professor
B. B. Boltwood made a report on the life of radium which may he
regarded as a study of inorganic evolution. Professor Theodore
Richards, of Harvard University, spoke of the investigations
recently conducted in the Wolcott Gibbs Memorial Laboratory.
These are in continuation of the work accomplished by Professor
Richards in the determination of atomic weights, which led to
the award to him of a Nobel prize, the third to be given for
scientific work done in this country, the two previous awards
having been to Professor Michelson, of the University of
Chicago, in physics, and Dr. Carrel, of the Rockefeller
Institute, in physiology.
