14 Thirty-eighth Annual Report of the 



formerly. The additions made are not large, and there appears no good 

 reason for incurring much expense in th-at direction. So long as the 

 collections can be preserved from the ordinary destructive agencies by 

 the present Museum staff, I see no reason for appointing special assist- 

 ants to perform the work. Were we even to look upon the matter 

 in its worst possible aspect, the salary of a special assistant would, in 

 five years, be sufficient to replace the entire collection with fresh speci- 

 mens. Of the stuffed skins, none can be regarded as types, or of special 

 historic interest, and only a few of them are rare and difficult to be 

 procured. I would therefore recommend that the special work which 

 has heretofore devolved upon these assistants be henceforth performed, 

 as in the past two years, by the assistant in charge of the Zoological de- 

 partment, with such temporary aid as he may require from time to time.
