REPORT OF THE ASSISTANT SECRETARY. 85 
If to the above we add the mollusea catalogued, by Mr. Carpenter, the record 
of which, filling an entire volume, is still in his hands, it will bring the total 
number of entries fully up to 100,000. As in all departments, excepting those 
of mammals, birds, and osteology, each entry may include a large number of 
specimens, it is a fair allowance to estimate an average throughout of five te 
each number, making half a million of objects catalogued (probably many 
more) and marked by permanent labels or figures. 'The average number of 
entries for the twelve years during which the system has been continued will 
thus exceed 8,000. 
DISTRIBUTION OF DUPLICATES. 
A very large number of specimens have been issued from the duplicate stores 
of the Institution, in 1864, both to public museums at home and abroad, and 
to gentlemen requiring them for special investigations. The following table 
exhibits the statistics of distribution as far as they could be reduced te 
figures :

The estimate, although somewhat approximate, is under the true amount 
of material distributed, rather than in excess. Mvery specimen included in it 
was carefully and authentically labelled before being issued. Of the birds 
referred to, 360 were mounted duplicates of the United States Exploring Hx- 
pedition, supplied to the Boston Society of Natural History and the Philadelphia 
Academy of Natural Sciences. 
PRESENT CONDITION OF THE MUSEUM. 
The specimens exhibited in the museum are all, apparently, in good condi- 
tion, free from insects, and nearly all properly identified and labelled. The 
series of fishes has been removed from the rooms under the art-gallery and 
placed in the northwest gallery of the museum hall, arranged for their recep- 
tion. A series of casts of interesting Mexican masks and other antiquities, from 
originals in the museum of the American Philosophical Society, has been 
placed in the eastern end of the northeast gallery. 
A large portion of the collections of the exploring expedision and Western 
American shells, intrusted to Mr. Carpenter for determination, has been re- 
turned by him, but they remain in the cases in which they arrived until the 
rest shall have been received, by request of Mr. Carpenter.
