Dear Mr. Li:
I am sorry that I must apologize for not being able to help you when you asked me to give you a letter of introduction to the director of the National InstITute of Oncology of my country.
Unfortunately I didnt see Director Tom Carter of the National InstITute of Oncology those days and I had no chance of mentioning your name to him. Because he was in a hospITal.
I will certainly mention you if I happen to run into him. I hope you will do well in your research work.
Yours sincerely,
E.S.Jones(Signed)
