APPENDIX TO THE REPORT OF THE SECRETARY. 



REPORT OF THE ASSISTANT SECRETARY, SPENCER F. BAIRD, RELATIVE TO EXCHANGES, 

 COLLECTIONS OF NATURAL HISTORY, &.C. 



Durino- tlie past year C7S principal packages of various kinds— boxes, bales, 

 or bundles— were received at the Institution, and 508 sent out from it by the 

 different express, railroad, or steamship lines. 



The fio-ures given above, however, do not represent the entire number of par- 

 cels received by the Institution, or made up and transmitted by it, since, as will 

 be seen by the subsequent tables, seventy-seven alone of the parcels scut out 

 were boxes for our agents of exchange, containing 1,176 parcels, thus increasing 

 the preceding enumeration by 1,100. Again, of the packages received 60 were 

 boxes from Europe, containing at least 5,000 parcels, making a total of at least 

 5,600 received, and of about 1,600 transmitted. n ■, t • 



As usual, the principal statistics connected with the exchanges of the Institu- 

 tion will be given in a series of tables, marked, respecti.vely. A, B, C, and D.

As the corresponding receipts in 1S64 amounted to 3,686, it will be seen that 

 1805 exhibits an increase of over 500 volumes and parts of volumes, thus indi- 

 cating that this source of supply to the library of the Institution exhibits no 

 symptom of diminution.
