Dear Johnston: 
I am glad you are pleased with the South American set. 
Some of the names on the labels are guesses or worse, but I 
wanted the duplicates to be where they will be studied and 
cited. 
Enclosed is a list of Lycium determinations from Professor 
C. Leo Hitchcock. 
Presumably I shall soon be off for rehabilitation duties 
at the University of the Philippines. There won’t be much 
time for collecting but I shall be surprised indeed if I don't 
get something. At any rate, I do not expect to be here for 
some months and shall not be clamoring for any identifications. 
Whenever you do study any of my numbers I'll appreciate it if 
you will drop me a note or a postal card. Eventually I'll 
make use of them. 
Sincerely yours. 
H, H.. Bartlett
