Thank you for your letter and your reprints of your letter to Science--We understand perfectly well your position based on

We have done a little bit more work on K12 and we will soon send you the copy of a short manuscript.
As you know, I am probably going to the states next summer. I still do not know how long I shall be able to stay and where
I will go. This will probably be worthy a [ . . . ] of money. Any way I hope very much to see you here or there and to talk
Best wishes for the New Year and best regards to the both of you from
