SPECIAL RESEARCHES. 



Little time has been at our command for special research. The De- 

 partment has no chemist, and the entire determinative work falls upon 

 the curator, who even makes a large proportion of his own analyses. 



The titles of such papers as have appeared during the year are given 

 in the Bibliography (sec. iv).
