Dear Ráy,

Thanks for your letter of December 10. I am actually very disappointed in not having to. go to Basle, as I would like an excuse for another visit there.:

The time is arproachirig when we will have to leave Switzerland. I expect to move to London some time between January 5 and January 10. My temporary mailing address there will be:

c/o Medical Officer in Charge
US Public Health Service
American Embassy
London W.1

I will sand you an address and telephone number as soon as we have found a permanent place to stay, so that you will be able to locate me, if you had anything you would like me to do.

Best wishes for a happy holiday season.

Sincerely,

Narres Harris Isbell
