From Chaim Weizmann Oakwood, 16 Addison Crescent, W. 14, 21 January 1922 My dear Professor, Your lines pleased me very much.[1] I believe it would be best if you would write to Mr. Berliner that he please send you the money. It could then be used for furnish- ing the Institute of Physical Chemistry, be it with books, apparatus, or the workshop.[2] I was in Paris & Geneva.[3] In Paris I spoke with a few professors, such as Had- amard and Widal.[4] There is great interest in the university there. In Geneva I saw the gentlemen of the League of Nations and I now do have the hope that our man- date will get ratified for once, at last, at the next session of the League of Nations.[5] That would be great luck. I am thinking of traveling to Palestine on the 25th of Feb., maybe my path will take me to Germany again. With many cordial greetings from both of us[6] to you and your wife and family, yours truly, Ch. Weizmann 33.
