Dear H r. White, 
I am enclosing a list of supplementary identif leatlona 
for your Mexican collect 'one of last year. Still remaining 
are the Conifers e and Sallcaccse which Mr. Hehder la supposed to do. 
These 1 have hope of obtaining soon 
In your letter of Jan. 24th you list foul! cases of 
Incorrect numbering which you detected in ray list of Identifications. 
These are my mistakes and, after checking hack on the specimens, I 
spree with the corrections you suggest. The I porno oa on pg. 7 of the 
list should read 1599 (not 1559). 
Your collection is now mounted ; nd in checking over It 
today I was once os?atn impressed with what e useful and very nice 
collection It Is. It will certainly he of sreat help to me. 
With kindest or regards, 
Yours sincerely.
