to their sympathies, made a great number of patriotic speeches. 

 Another was county chairman for the U. S. P. S. R., and another 

 was a captain in the R. O. T. C. and later an instructor in the S. 

 A. T. C. 



MEDICINE. 



Several medical members did valiant work fighting the "flu" on 

 the home front. Others lectured before the soldiers and the S. A. 

 T. C. and one was director of the Iowa Child A\'elfare Research 

 Station. 



PHYSICISTS. 



The war work of the members of the Academy who are physicists 

 differed widely. One of our members gave a series of lectures at the 

 naval camps on "The Earth, Magnetism and the Compass," and 

 "The Ocean Tides;" one was senior instructor in charge of all 

 technical instruction at a Signal Corps Officers Training School : 

 one was "Assistant District Educational Director" of District No. 

 8, under the Committee on Education and Special Training of the 

 War Department ; two were members of the Committee on Loca- 

 tion of Invisible Aircraft of the National Research Council, one as 

 chairman ; one was a captain in the army and assistant engineer 

 engaged in experimental work in connection with the flight of air- 

 plane bombs; one was captain and later major in the army and de- 

 voted himself to the ordnance features of airplane service; one was 

 a non-commissioned officer in the Signal Corps and an active par- 

 ticipant in experimental work in the development of the wireless 

 equipment of airplanes ; another was employed as special agent to 

 assist in locating men in diff'erent branches of the service ; and those 

 remaining on duty in the colleges were actively engaged in S. A. 

 T. C. instruction. It is impracticable to discuss the individual suc- 

 cesses of the members. They found themselves utilized in a highly 

 specialized capacity, as teachers, as executives in connection with 

 education and with army and navy research, and virtually as devel- 

 opment engineers in the employ of the army and navy. In fact, 

 experience during the war showed that the physicist possessed the 

 api)ni])riaU' training and the suitable attitude of mind for a develop- 

 ment engineer. The profession of physicist has more than ever 

 become recognized as having an important function in the develop- 

 ment of applied science. 



PSYCHOLOGISTS. 

 'J'he members of the Psychology department of the State Uni- 

 versity were engaged in devising acoustic insirunicnls for use by
