Dear Dr. Robinson:- 
I have your letter of March 29. I think the best address to use 
for mailing publications will be Botanical Department, Brown University. 
This is what Dr. Snell also seems to think would be best. 
Just at present it seems impossible to tell you just what gaps 
may occur in the series of Contributions, as Dr. Snell has, at the 
present time, a man reorganising the pamphlet collection, and nobody 
seems to know just where to put their hands on this series. As soon 
as they are uncovered or discovered I have asked them to re£>ort to 
me and l v/ill then communicate with you again. 
Very sincerely 
J. RRAMLIII COLL IMS
