I was ‘delighted by your recent® “Yettér°with all its details of Grabar's
visit in Madison. A jotrat. ipople from our lab is visiting you, I under-
stand and Wisconsin is, ind I than ever, a big center.

This letter is speedily sant to you as I just realize that Jacques
Monod has been visiting yor, now. Did he gave you the Chinese "estampage"
and the little catalogue,as ke was supposed to do sos if I ask you this
question it is because we know his absent-mindedness and I would be
much disappointed if he had forgotten . We do like these Chinese engra-
vings, Suzan and I, very much,and we hope it will suit well your new
house.

As you probably know,I am now back from a little convalescence trip

in the Midi and very anxious to go back to work heavily, as I have in
my mind so many things I planned to dofluring all these months of semi-
inactivity: before anything else I want to push the purification of the
neurotoxin of the Cobra venom and get an answer about it being the same
fraction as the lecithinase of the venom and also to confirm that it
is really a small polypeptide molécule. The second dir.cction being the
study of the lecit:.inase-unti lecitinase reaction# which I am just
beginning.

I have been promoted,recently a member of the Pasteur Institute and
I hope it will help me in getting more financial help in my work , it
is also morally nice to get into this good old family house, despite
all its little struggles, specially after 9 years during which I was
working in its lab without being a member of the staff. |

I will look around for the Pasteur's work and also willask the main
French Scientific publishers to send you theirs catalorues.

I have no ideas about the flagel&as antigenic snecificity in Salmo-
nella but I guess that an immunological analysis in gels may be of

interest to study it. I will ask Cludin what he thinks of the prospect?
