Five of these form a portion of the Journal before alluded to, 

 three were returned to the author, one was withdrawn, one is now 

 about going to press, and one has been held over until next year. 

 The others have been printed in the Proceedings. It is gratifying to 

 find in this connection that representatives of departments of the 

 United States Government, and of several important educational 

 institutions including the Agricultural College of New Mexico, the 

 Leland Stanford, Jr. University, the Smithsonian Institution aud 

 the University of Pennsylvania have found it to their advantage to 

 avail themselves of the facilities for securing early date of publica- 

 tion afforded by the mode of issue and distribution of the Academy's 

 Proceedings. It is earnestly urged that as soon as the Academy's 

 means will permit, the numbers as issued be distributed free of 

 charge to all members of the society in good standing.

 issued 231 pages and 11 plates of the Entomological News, 128 pages 

 and 2 plates of the Transactions, and 202 pages of special papers. 



The publications of the Conchological Section during the year have 

 consisted of 143 pages and 27 plates of the Manual of Conchology.
