Dear Daddy,

I was disturbed to learn you had lost you libel case. It strikes me as very odd that in New York there is one law of libel for the rich and another for the poor. It seems to be misdirection by the judge. Can you take it further or is the Supreme Court of New York the Supreme Court?

Do you know anyone in Warsaw or anyone in Prague I might go see? I am planning to go to the Moscow meeting July 11th to 22nd, visit Czechoslovakia for a bit. Visit Peter Waser and, others for a bit in Switzerland, and go to the Biophysics congress in Vienna. I am pushing my model structure of molecules active in cholinergic systems. Is there any way I can lift some of your blocked rouble account in Moscow? I do not think there is. I think you have to go there. How about coming? I will stop off in Poland if I can and there is anyone to see. There are a lot of crystallographers of one sort or another in Poland. If you know anyone special, let me know please, because it is getting late to arrange things. I still do not have enough money to go but I hope sufficient cones through.

Cholinergic systems are going well. I think my model is pretty good, based on the three known relevant crystal structures. I have been meaning to send you a list of publications. I shall do so. It is not very impressive. I am having trouble getting some things describing instruments published. I have to find a suitable journal. I think they are worth publishing. Lots of new ideas and I might get a consultancy somewhere.

I saw Bernal yesterday. He is better but still in a bad way. He says he wrote to you about the nuclear structure. You should send him a set of reprints if you have not already. He cannot walk at all really, and has great trouble talking. It is tragic.

You should come see us. We only fixed the bloody house in order to be able to receive you and Mamma. Now you don't come.

I am likely to be busy for several years on the cholinergic stuff. I will probably not be able to do the only worthwhile experiment, determine the structure of one of these molecules and the receptor or acetylcholinesterase.

We are reasonably well. Sarah has grown up a lot the last fortnight or so. Before that she refused to cease being a baby and was a bit of a pill in ways. Thos. is fine. Too sensitive and sulky at times but I think he will be all right. Julia is quite well. I am a bit up and down, depressed, excited. Too impatient. Work goes too slowly or I cannot somehow go faster.

I have had several fine letters from Crellin. He seems in good shape.

Much love,

Peter
