Dr. Dugand I am sure will arrange to put you in 

 touch with workers in the Rockefeller Laboratories which 

 are connected with the government* I hope that it will , 

 be practicable for you to go down into the tropical zone ofc 

 Villavicencio to see this region. 



Necessarily details for your itinerary will be 

 left to your own discretion because of your familiarity 

 with the work in hand, and of the fact that you will be 

 working at a distance from Washington* 



Please keep me informed as to your address and the 

 progress of your investigations • May I ask also that you 

 remember me to my many friends in Colombia. 



Sincerely 



A» Wetmore, 

 Assistant Secretary*
