Panama, R. de P. 
Dear Col. Hertig: 
I have just received Dr. Clark’s letter and write 
to thank you lor your friendly consideration relative to 
the release of Ratibor Hartmann. This will be of major 
assistance to me in the work that I have in mind. 
I learn from Dr. Clark’s letter that you are going 
to Paraguay so that it appears that I will not see you this 
trip. 
With my best regards and my best wishes for full 
success in the south, I am 
Sincerely yours, 
lp 
A. Wetmore, 
Secretary.
