REPOKT OF ASSISTANT SECRETARY. 15 



this series. Much material already entered in the earlier volumes of 

 this series has been reentered in the later volumes. In the Depart- 

 ment of Metallurgy and Economic Geology an endeavor seems to 

 have been made to enter all material of a like nature in separate cata- 

 logues ; thus, in the year 1S89 three catalogues (Vols, xi, xni, and xiv) 

 were in use in this department. All of these books are as yet unfilled.
