München, February 28, 1928

Dear Professor Raman:

I thank you sincerely for your kind cable: I shall be very glad to spend some time with you in Calcutta and to give some lecture there. Please write me how long you expect me to stay at your university. I made, at Como, a provisional arrangement with Prof. Saha to come for some days to Alahabad. I hope you may be willing to put in order my program for India together with Prof. Saha. Therefore I am enclosing my letter for Saha, and beg you to read it and to send it on. I shall have altogether something like four weeks to spend in India.

Very faithfully yours,
[A. Sommerfeld]
