REPORT OF THE CURATOR OF THE WILLIAM S. 
YAUX COLLECTIONS. 
The Curator of the W. S. Yaux collections submits his report for 
the years 1889 and 1890. 
The collections are in good condition. One hundred and forty 
specimens were added during the two years embraced by the re¬ 
port, at a cost of $379.28. Sixteen upright cases have been pre¬ 
pared at an outlay of $523.22, and placed above the horizontal 
cases for the proper systematic arrangement of the additions. 
The additions now reported increase the number of specimens 
in the Mineralogical collection to 7,028. No additions have been 
made to the Archeological collection, and the specimens at present 
number 2,940, the same as reported in 1888. 
Respectfully submitted, 
Jacob Binder, 
Curator.
