Dear Riley:

I am pleased to have your two letters. I have written to Queen’s University in connection with your application for the Chowh Research Professorship.

I shall be pleased to provide a reference for you for the Intermediate Fellowship in Cancer Research, when the Cancer Campaign people get in touch with me. They have not yet done so.

I think that the U.S.C. matter has turned out the way it should, considering their financial situation.

I am very glad to know about your conclusions about α1 and α2, and I look forward to seeing your published paper. I am also very much interested to learn about the state of the histone in calf thymis nucleoprotein. I judge that you mean that the histone is present as an α helix.

I am also glad to learn that you have some good data on various sorts of nucleic acids. Dr. Rich here had been considering whether he should go ahead with a study of this sort – you know that we have been interested in it. I myself feel that there may well be a large number of nucleic acid structures.

Corey and I are glad to give you permission to reproduce our drawing of the α helix.

Things are going along well here. I am getting started on a new attack on the problem of the structure of collagen. I think

that it may be that our proposed structure is completely wrong. At any rate, we are hoping to make a thorough analysis of the situation.

With best regards, I am

Sincerely yours,

Linus Pauling: W
