LIBRARIAN'S REPORT. 139 



from the Wisconsin Academy. The Redwood Library, Newport, 

 R. I., sent two boxes of miscellaneous duplicates, from which 

 we have secured several valuable papers. 



About 25 volumes and 100 reprints have been secured by the 

 exchange of duplicate material. 



The following sets have been completed this year: 



Experiment Station Record, 



Proc. Zool. Soc. France, 



Chemical Abstracts. 



The assistant librarian has kept a constant watch for oppor- 

 tunities to secure desirable accessions, as was proposed last year 

 when a special fund requested was set aside for this purpose. 

 The good effects of an extensive preliminary study and corre- 

 spondence to prepare for such enterprise are now seen. Of the 

 $500 set aside for the purchase of second-hand books and 

 periodicals, $342.60 has been expended and 251 volumes secured. 

 Important monographs by Weismann, Garbowski, Blochman 

 and many other bargains were secured; a full set of Wallace and 

 Huxley were added ; 33 leather bound volumes of Popular Science 

 Monthly, in perfect condition, were bought at 30 cents each. 



89 volumes have been added to incomplete files by securing 

 missing parts. In this way substantial progress has been possible 

 toward making up deficiencies. This method of building in lost 

 parts, now feasible for the first time, is as important as extension 

 From now on desirable bargains are apt to appear in numbers, 

 which will enable us to systematically follow up this campaign. 

 This should be done! 



The serials listed below were not on our shelves last year: 



Abstracts of Bacteriology, 



Journal of Genetics, 



Memoirs Zool. Soc. France, 



Archives Russes d'Anat. d'Hist. et d'Embryol., 



Journ. Russe de Zoologie, Revue Zoologique Russe,

The last two journals have been secured by exchange with the 

 BIOLOGICAL BULLETIN.
