Dear Dr. Barnhart: 
I send you, herewith, a photostat copy of a Chronological List 
of the Dissertations of Charles Linnaeus, which I had prepared in the 
hope it would lead ultimately to our securing in this country a com¬ 
plete set of these valuable publications. According to the latest 
information at our disposal the lew York Botanical Garden Library 
contains eighty original Linnean dissertations. If by good fortune you 
have more than this please let me know so the second issure of this 
list can be corrected accordingly. 
Yours very sincerely 
Chairman o f the Library Commit tee
