Abstract :
In selecting subjects which would become the major study of the committee during the year, an effort was made to choose those which seemed to be lagging in progress because of unorganized attention, or to be only imperfectly coordinated and recorded because of their relatively recent development. Two subjects were chosen, one on each of these bases, and subcommittees (with chairmen, H. B. Brooks and C. M. Jansky respectively), were appointed to make the survey.
