Dear Prof. Rainman,
I'm sorry I couldn't make our 11 o'clock appointment. Prof. Wolf's lecture lasted a lot longer than I expected. I could meet you in the library Reading Room 4 tomorrow at 10, if that is convenient for you. If not, please leave a note in my mailbox ＃334, this afternoon.
A friend of yours, Li Ping, made a long distance call from Xi'an this morning while you went out. She asked you to book an air ticket for Shanghai at 9 o'clock, August 5, and make a reservation for hotel room tonight. I am sorry that I can't pass on the message to you in your presence, because I was ordered to do something urgent. See you then.
I very much regret I was unable to attend school this morning owing to a severe attack of illness. I am enclosing herewith a certificate from the doctor who is attending me, as he fears it will be several days before I shall be able to resume my study. I trust my enforced absence will not give you any serious inconvenience.
I have done all my things here. I sincerely thank you for the trouble you have taken for my sake. I am leaving for home by train at two this afternoon. This is to say good bye to you. Please kindly remember me to your wife.
