Upon motions, seconded and carried, the nominations for 

 President, Vice-Presidents and Secretaries were closed. When 

 the nominations for Treasurer were in order, Dr. Sander asked 

 that, in view of his long service in that office, he be allowed to 

 decline the nomination. He stated that he did this with regret, 

 since he had hoped that he might complete a half-century in 

 the service of the Academy, but that the condition of his health 

 did not allow him to be sure that he could be present at the 

 meetings. He placed in nomination Dr. Charles D. Stevens. 

 Dr. Stevens asked that his name be not considered, but his ob-

 by Professor Nipher, it was voted to place the name of Dr. 

 Stevens on the official ballot. Upon motions the nominations 

 for the other offices were successively closed, and the report of 

 the committee accepted. 



Dr. Enno Sander presented a volume entitled "The Hoot of
