No especial event affecting the welfare of the library has occurred 

 during the year; the endeavor has been to rotmd out the work along the 

 usual lines. With the activities of the ctiratorial staff largely engaged in 

 preparations for moving to the new building, their requests for books 

 were comparatively few during the first half of the year. With the ces-

 first volimie of The Monograph of the Pheasants, by William Beebe, 

 was published by the New York Zoological Society; a beautifully il- 

 lustrated work of these gorgeous birds in their native haunts, to be 

 complete in four volumes. When the attention of Mr. Edward E. Ayer 

 was called to the work he immediately subscribed to the set for the Ayer 

 Ornithological Library of the Museimi. Mr. Ayer has also presented 

 copies of Seth-Smith's Handbook of the Imported Species (parakeets), 

 and Whitaker's Birds of Tunisia. A niunber of desirable and valuable 

 publications were received from contemporary institutions, both domes-

 number was especially noticeable because of the enormously enhanced 

 cost of book-production. The Museum was most fortunate in receiving
