 were placed on duty with the Morale Branch of the General

 a report upon preliminary experiments for the various methods 

 that had been recommended for use in the selecting of lis-

 for this service. One of these Instruments was an audiometer 

 designed in cooperation with Professor A. H. Ford. Two re-
