Dear Joshua:

Thank you very much for your letter. My schedule
is now the following: I shall leave here cune lth.
Retween dune 14th and 15th I shall be at the Ziba Founda-
tion in London. Cn June 17th I shall be in Boston (c/o
Dr. Balaes, Retina “oundation, 70 Sharbers Street,
Eoston 14) and on dune 1£th I shall so to Kingston.
tne meetings end on dune 21st and I have planned to go
down to Phiadelvhia and see Jack SGehultz for one or
two days after the meeting. I have passa#e reservation
back fron xew York to Stockholm on June 29th which is
the latest day ween I have to leave. In the reantine,
that is between about cune 25th and 2°th, I should be
available for a trip to Madison. As I said tcefore, I
sno ld be delishted to core but I dont think it would
be right 17 you would nave to so to svecial troubles
to arrange this, varticularly sinée there are zood
chances for us to meet next year. As far as finances
are concemed, 3 125 is nore than needed since it would
only be necessary to cover air transportation on the
route Philadelphia-Madison-New York. If you can secure
tais without tajor trouble and you are rot too busy
with other thines, I should love to core. If the time
is not very convenient for you or there are other daif-
ficulties, however, I shall also verféctly understand
and we can meet next year. So olease consult your oom
convenience and just let re know how you feel about
it. You can reach me at one of the above adresses.

As to the Gatlinburg meeting I think “that the
combination with the symposium in Madison sounds ex-
celicis. If I can come to Gatlinburg, I shall certainly
come to Madison too. I have corresvonied with Dr.
Hollaender about the forver and, as usual, it will
depend on the possibility of arranring transatlantic
passace in one way or another. There is very little
chance to have it covered from the Swedish side.

I have not heard from Francois Jacob as yet. The
errangerents for the Internatiznal Congress of “icro-
biology are progressing slowly but definitely. There
is no doubt about it that the Tonsress will be able to
contribute to your vassage and invite you snecially;
what is not known at the present moment yet is the exact
amount the Congress will be able to offer. Donations
are still coming in and the economic situation will
not be clarified before Centember. I am sure, however,
that something will work out.

iy professorship nas now been Finally approved

by the Farliament, as of duly Ist this year. This
settles the question about Wister.

Hoping to see you either very goon or next year,
and with kindest revards to both Ester and you,

Sincerely yours,
fame.
