Dear Josh,

It was nice to hear from Boris Ephrussi that Ester and
you will be able to come in Paris next March. This letter is
therefore to invite you to give a talk at the Club de Physiolo-
gie cellulaire, which has a monthly session at the Institut de
Biologie physico-chimique, 11 rue Pierre Curie. Generally,
the sessions are all on Friday evening at 6 P.M. Exceptionally,
if Friday was not convenient for you, I could probably change
the day and arrange it for Tuesday March 12 as you wrote to
Boris. These are very informal meetings where various aspects
of physiology are discussed. Sessions are in French, but every-
body will helpljif you have troubles with your French.

As Boris told you, we can give! 60,000 frances to cover both
Ester's and your trip from London to Paris as well as your
stay here for several days.

The problem of getting an exchange order from Air France
appears to involve many difficulties. We have to fill many
forms in order to make an application. We shall probably not
get it, and if we get it, it could take a long time. Ma I
suggest one of a3 possibility at your convenience

1) you can take care of 60,000 francs and exchange them

2) We can buy for you,London~Paris-London reuntreé tickets
on Air France for the time you want # and send them to you and
you take care of the difference.

3) We can exchange the’ 60,000 francs against dollars
through an American worker’ who will send you a cheque in
Madison. However, the rate of exchange might be rather low
(something like 410 - 420 francs).

Please tell me as soon as possible whether you can give
your talk on a Friday and whether you prefer Tuesday ? And
which financial solution you favored.

We are looking forward to see you.
Best regards to both of you,

Francois JACOB
