" JMicroscopic observations '" of which the Hbrary ])ossesses 1667 

 and 1780 editions respectively. 



Accessions 



During- the year J 929 tliere were added to the Hl)rary 1.767 

 voknnes and 1,509 pamphlets, makinj^ a total collection on De- 

 cember 31 of 15.091 volumes and tt,to8 pamphlets, or a grand 

 total of 26,199. ] resides the abcjve volumes and pam]ihlets there 

 were received 6.667 P^i^i'ts of jxiblications which will be bound 

 and accessioned later when complete volumes have been issued. 



Idle number of volumes added by purchase was somewdiat less 

 than for the previous year, ddie funds allotted for the purchase 

 of books were exhausted some time before the end of the year 

 and many order slips which had already been written had to be 

 filed and held for the beginning of the new year. This will result 

 in considerable inroads on the ensuing year's appropriation at the 

 very commencement and reduce by so much the number of other 

 desirable books that can he purchased. This is ])articularly un- 

 fortunate at this time l)ecause of the large num1)er of sets of 

 botanical periodicals, serials, and other scholarly ])ublications which 

 are now in the market. Catalogues from English and European 

 booksellers are being received constantly and checked for works 

 needed for the library, only a fraction of which can be ordered 

 l)ecause the income from the s])ecial book funds is insufficient for 

 the purpose. Several rare botanical classics were ])urchased from 

 the income of the P>enjamin Stuart Gager Memorial Fund, but the 

 opportunity of securing- a number of other Pre-Einnean works 

 had to be lost.
