32 Report of the President. 



During the year 15,573 cards have been received from the 

 Concilium Bibliographicum and intercalated in the original 

 set. This has proved to be one of the most complete and 

 practical bibliographies of biological subjects, and has been 

 much used. In addition to this set the Concilium has recently 

 deposited in the American Museum of Natural History a com- 

 plete set of its cards. These are for the convenience of 

 American purchasers, who can thus obtain the cards at the 

 same price as from Zurich, but with the saving of much time. 

 The Museum has undertaken this gratuitously for the benefit 

 of American biologists. 



During the past year the Museum has sent the following 

 letter to one hundred Institutions in selected centers: 



"The American Museum of Natural History desires to 

 place its publications in certain institutions where they may 

 remain as complete, sets for all time. We are therefore asking 

 you if the name of your library may be placed upon a list of 

 one hundred institutions to receive the 'Memoirs' and 'Bul- 

 letin ' of the American Museum, with the understanding, first, 

 that these publications be sent gratis, and second, that they 

 shall be made available for reference and study for those in 

 your locality who may be disposed to avail themselves of the 

 general privileges of your institution." 



Replies have been received and publications sent to ninety- 

 eight of these institutions. 



Following is a list of the scientific publications of the 

 Museum issued in 1904, as received by the Curator for distri- 

 bution and exchange:
