Dear Doctor Schmitt; 
I appreciate your kind letter of November 10 regarding your 
soil samples and hope that you have had some success in hairing these 
studied, I have not had an opportunity to talk to Dr, Welch recently so 
I do not know if you have discussed the matter wilh him. 
Your mention of the DuPonts having an interest in antibiotics 
surprises me, I did not know that they were doing research in this field. 
We are currently having the Merck people make an antibiotic 
for us for experimental use which was why I had suggested them, but there 
are many others in this field that I know quite well. 
If I can ^ve you ar^y assistance, please let me know. 
Kind regards and best wishes. 
Sincerely yours.
