Dear Joshua:

Within a few days I will leave for Boston where I will stay towards
the end of the month. My address there is Children’s Cancer Research
Foundation, 35, Binney Street, Boston,

May I trouble you to drop me a note or cable there if your plans
about Stockholm should have changed, Now IJ have reservation which takes
me back to Stockholm April the 22nd. If you should not come to Stockholm,
I would, however, prefer to stay another week in Boston.

With personal regards, Iam,

Very sincerely yours,

Torbjérn Caspersson
