Dear Dr* Masons 
Herewith is the list of Bock specimens undetermined at 
the University of California which you sent me and to which I have 
added as many names as we have recorded. It appears that not as many 
Beck specimens have Been determined as I anticipated. 
I suggest that you record names here given in full and return 
this list to me. I shall put it with the Book hook and every time a 
determination is reoordecl in the hook l shall add it also to this list. 
Shen when it seems feasable 1 shall send it again to you, thus gradually 
getting your unnamed material labeled tip. 
Sincerely yours,
