APPENDIX TO THE REPORT OE THE SECRETARY. 



Smithsonian Institution, 

 Washington, December 31, 1860. 



Sir: I have the honor herewith to present a report for 1860 of the 

 operations you have intrusted to rny charge, namely: those which 

 relate to the printing, the exchanges, and to the collections of natural 

 history. 



Very respectfully, your obedient servant, 



SPENCER F. BAIRD, 

 Assistant Secretary Smithsonian Institution. 

 Prof. Joseph Henry, L.L. D., 



Secretary Smithsonian Institution. 



PRINTING. 



The publications of the Institution printed during the year 1860 

 consisted of 614 quarto and 641 octavo pages, illustrated by seven plates 

 and sixty-six wood cuts. 



EXCHANGES AND TRANSPORTATION. 



During the year 1860 there has been a very great extension of all 

 operations connected with the department of exchanges. The receipts 

 by the Smithsonian Institution have been much enlarged over those of 

 any previous year, and an increased use has been made by other 

 parties of its facilities both for the transmission and return of pack- 

 ages. 



The following tables will be found to exhibit the statistics of this 

 branch of operations of the Smithsonian Institution, showing how im- 

 portant a part it plays in aiding the scientific and literary intercourse 

 of different parts of the globe. 



The expense of the system of exchanges, however, has been correspond- 

 ingly increased, and would have been greater than the Smithsonian in- 

 come could defray without the many favors from transportation com- 

 panies, in the way of material reduction or entire remission of charges
