42 NINTH ANNUAL REPORT OF 



in addition 1.o the complete series of specimens to be retained on the 

 shelves. 



Among the more important collections thus distributed ma}' be men- 

 tioned one of 145 species of North American birds, in 199 specimens, 

 to the Swedish Academy of Sciences at Stockholm, in return lor a very 

 valuable collection of skins and skeletons of north European mammalia ; 

 97 species and 160 specimens of North American birds to Mr. F. 

 Sturm, of Niirnburg, in return lor collection of birds, &c., li'om central 

 Europe ; 104 lots of fishes and invertebrates to Professor Agassiz, of 

 Cambridge, in return lor numerous donations of duplicates- from his 

 pre-eminentU'' valuable collection ; fishes of Massachusetts to Dr. D. 

 H. Storer, of Boston, to assist him in the preparation of his memoir on 

 the fishes of the State ; numerous birds and quadrupeds, both European 

 and North American, to the Philadelphia Acadenw ot" Natural Sciences; 

 eggs of American birds to Dr. T. M. Brewer, tor his work on North 

 American oology ; large numbers of North American coleoptera to Dr. 

 Leconte, for his memoirs on this department of entomology, &c. The 

 list is capable of considerable extension, but thei'e is enough to show 

 how the Institution has endeavored to co-operate with all societies and 

 individuals, engaged in special investigations, re(]uiring materials ad- 

 ditional to those already in their possession. 



It will, however, be sufficiently evident thai the Smithsonian In- 

 stitution cannot indiscriminately undertake systematic exchange of 

 specimens with other parties — with individuals especially. The force 

 of the natural history department is not nowsuflicient tor this, and may 

 never be. To the mere collector, as distinguished from the investigator, 

 it will not be expedient to distribute specimens to any considerable 

 extent, as the disposable stock may be reduced so low as to render it 

 difficult or impossible to do proper justice to the student. While, 

 however, the Institution canned undertake the mere business of exchange 

 with individuals, unless in exceptional cases, and even with institutions, 

 it can do and has done much to facilitate such exchange between other 

 parties. Scarcely a week passes without the communication of infor- 

 mation of the readiness or desire of exchange in particular departments 

 on the part of different individuals or associations. AH notifications or 

 applications of the kind are systematical^ recorded in the proper 

 books and duly referred to when occasion requires.
