twenty-four hours being nearly divided between them. 6. Laborers, 

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

 open to the public, attending to fires, &c. 



Besides the assistants who receive a salary, a large amount of labor 

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

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

 tions and make use of the facilities afforded by the library and col- 

 lections in preparing their reports. To most of these, rooms, warmed 

 and lighted, have been assigned in the building, and lodging apart- 

 ments in the towers. Among these we may mention the names of 

 Mr. F. B. Meek, Dr. W. Stimpson, Dr. Gill, Mr. R. Kennicott, Dr. 

 E. Coues, Dr. H. Allen, Dr. E. D. Cope, and Mr. A. D. Brown. 



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

 Dr. B. F. 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. 



For 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 world, and to collect the returns intended for 

 this country. The following are the agents at present employed : 

 Dr. Felix Flugel, Leipsic ; Gustave Bossange, Paris ; 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 

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

 ance in 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.

 Secretary Smithsonian Institution.
