The Librarian reported that during the summer efforts were 

 made to complete the various sets of pubHcations in the hbrary 

 by requesting the societies exchanging with the Academy to fill 

 in the parts wanting. Some 393 volumes and 603 numbers 

 were received, completing 40 sets and many volumes. 



Miss Mary J. Klem presented to the museum a large and 

 finely preserved specimen of Sigillaria from the Lower Coal 

 Measures at Veedersburg, Indiana. The specimen is interesting 

 because of its large size, branched condition and excellent state 

 of preservation. 



Miss Klem also stated that she had secured photographs of 

 some of the early members of the Academy, among them pictures 

 of Professor G. C. Broadhead, August Fendler, Dr. Theodore C. 

 Hilgard, Professor A. Litton, Professor J. G. Norwood, Dr. C. C. 

 Parry, Dr. Gustav Seyffarth and Professor G. C. Swallow. 



The President called the attention of the Academy to the fact 

 that the recommendation of the Council that Dr. Enno Sander 

 be made an honorary member of the Academy, as a mark of 

 appreciation for his long, faithful and efficient service as Treas- 

 urer, could be acted upon at the present meeting. Mr. Kinealy 

 moved that the Academy proceed at once to ballot. The mo- 

 tion was seconded by Dr. C. D. Stevens, and unanimously car- 

 ried. Mr. Kinealy was appointed teller and reported twelve 

 ballots cast, all in the affirmative. The President then declared 

 Dr. Sander elected to honorary membership. 



Dr. J. Arthur Harris presented a brief report of the Interna- 

 tional Zoological Congress held in Boston during the summer. 



Professor Woodward presented further notes on the me- 

 chanics of aerial navigation. 



Mr. D. I. Bushnell was unanimously elected to membership.

Dr. William Trelease delivered an illustrated lecture on 

 ''Variegation in the Century Plant and Other Agavis." Varie- 

 gated individuals are quite common among the agaves, but little 

 is actually known of their origin. Dr. Trelease exhibited young 

 plants of various agaves, showing variegation.
