1870.] 315 [Annual Report. 



The binder, having attended to the most important series 

 in the library, has recently been dismissed. During the past 

 year one thousand and ninety eight newly bound volumes 

 have been placed on the shelves, a number of repairs made 

 and one hundred and twenty copies of the Proceedings 

 covered. Work has also been done for outside parties, *and 

 the signatures of the Proceedings and extras issued to au- 

 thors, folded. Special reference should here be made to 

 the Harris manuscripts ; the binder has secured the most 

 delicate fragments with such ingenuity and skill that both 

 sides of the manuscripts can be seen when necessary, without 

 danger ; thus all may inspect these valuable memoranda and 

 mementoes. 



The assistants in the library have continued the revision 

 of the Card Catalogue and completed about one third. The 

 remarkable growth of the library has delayed the progress 

 of the work, not only from the time required to attend to 

 the new accessions and the preparation of unbound series for 

 the binder, but also from the changes necessitated in the 

 arrangement of the cases. We shall soon be obliged to build 

 the gallery in the back library. The pamphlets have contin- 

 ued to receive constant attention whenever time permitted, 

 and from one fourth to one third of the older pamphlets, as 

 well as all the new donations, are now accessible. 



The Librarian has recently made an enumeration of the 

 books ; they have been counted as bound, whether contain- 

 ing more than one volume, as is frequently the case, or not ; 

 the parts have been estimated at their proper proportion of 

 the volumes to which they belong and the pamphlets counted 

 separately ; this enumeration therefore gives the number at 

 its least valuation, and is proportionally a much smaller esti- 

 mate than those previously made. There are 9,396 volumes 

 and 2,677 pamphlets. Of these volumes 1,010 belong to 

 general literature, mainly deposited by A Republican Insti- 

 tution ; 806 are botanical, 453 entomological, 402 geological 

 and mineralogical, 510 encyclopaedic ; 613 treat of verte-
