PROCEEDINGS OP THE ACADEMY OF 



[1890. 



Letters accompanying publications number thirty-one and indi- 

 cate in great part the number received through the International 

 Exchange. 



The demand for missing parts of our publications has been less 

 during the past year than formerly, indicating the greater degree of 

 safety in mail transmission. These deficiencies we have in every 

 instance endeavored to supply. 



During the year eight correspondents have been elected and noti- 

 fications sent. Acceptances have been received from nearly all. 



Formal notifications of the death of four correspondents have been 

 received. 



With this, my fourteenth annual report, my official connection 

 with the Academy in this position ceases. In conclusion I desire to 

 return my thanks for the compliment paid me in the repeated elec- 

 tions, which have made my service so long. 

 Respectfully submitted, 



George H. Horn, M. D., 



Corresponding Secretary.
