 daily required for cleaning the building after the hours in which it is'

 has been given the Institution, without pay, by persons interested in 

 the study of natural history, or who have been engaged in explora-

The laboratory has been under the care, for the last few years of 

 Dr. B. P. Craig, now of the medical department of the army and 

 also of Dr. Wetherill, just appointed Professor of Chemistry in the 

 new^ college at Bethlehem, Pennsylvania. The remuneration they 

 received was either from the government or from private parties on 

 account of researches principally of an economical character. 



Fr^- the purpose of conducting the foreign exchanges, it has been 

 found necessary to have agents in such central positions as may en- 

 able us to distribute the books and specimens most effectually to 

 various parts of the Avorld, and to collect the returns intended for 

 t^iis county. The following are the agents at present employed : 

 Dr. ^ehx Flugel, Leipsic ; Gustavo Bossange, Paris j William Wes- 

 ley, London ; Fred. Muller, Amsterdam. 



The collaborators, to whom references have so frequently been 

 made, include all the prominent cultivators of original science in this 

 countiy. They have all, with scarcely an exception, rendered assist- 

 ance m supporting, directing, and advancing the Institution. Its op- 

 ponents have been mainly those who have been misinformed as to its 

 character and labors, or have been disappointed in the desire to ad- 

 vance personal interests through its means. 

 Respectfully submitted.
