APPENDIX TO THE REPOET OF THE SECEETARY.

From the preceding tables it will be seen that the average entries per year, 

 for fifteen years, have been about 7,450, and that those for 1865 amounted to 

 15,925, the difference between the summations for 1SG5 and 1S64. This, how- 

 ever, includes about 7,600 entries of shells made during several yeai-s past by 

 Mr. Carpenter, and only reported in 1SG5. 



As repeatedly explained in previous reports, it is only in case of the osteo- 

 logical specimens, the mammals, and the birds, that each entry necessarily re- 

 lates to but one specimen. In the other departments all of the same kind, 

 from one locality, and collected at one time from the same donor, may have 

 but a single entry number, although this number should be affixed to all the 

 specimens. The average of specimens to each entry cannot be determined ac- 

 curately, but it is probable that five will not be too high, thus giving as the 

 total number of specimens catalogued over half a million. 



The following tables present an enumeration, somewhat approximate indeed 

 in some cases, of the specimens of different kinds, as well as the names and ad- 

 dresses of the parties receiving them, whether public or private. Many of the 

 latter have made contributions of greater or less value to the Institution, which 

 were then reciprocated ; and some required the specimens for scientiHc investi- 

 gation. From very few of the institutions, however, has anything been ever 

 received, nor is any expected.
