  Dear Dr. Branson:

  I enclose a draft of a manuscript which we propose to publish in the Proceedings of the National Academy of Sciences. Dr. Weinbaum did a great amount of work, based on your original notes, and I think that a discussion of the configuration of the spirals is in good shape.

  Please let me know if there are any suggestions that you want to make about the wording of the paper. Also let me know if it is satisfactory to you to publish it in the Proceedings of the National Academy.

  With best regards, I am

  Sincerely yours,

  Two Hydrogen-Bonded Spiral Configurations of the Polypeptide Chain

  Sir:

  During the past fifteen years we have been carrying on a program of determination of the detailed atomic arrangements of crystals of amino acids, peptides, and other simple substances related to proteins, in order to obtain structural information that would permit the precise prediction of reasonable configurations of proteins. We have now used this information to construct two hydrogen-bonded spiral configurations of the polypeptide chain, with the residues all equivalent, except for variation in the side chain.

  We have attempted to find all configurations for which the residues have the interatomic distances and bond angles found in the simpler substances and are equivalent, and for which also each CO group and NH group is involved in the formation of a hydrogen bond. The plane layer of extended polypeptide chains is a structure of this type, the hydrogen bonds being formed between adjacent chains. In addition there are two spiral structures, in which the plane of the conjugated system C--CO--NH--C is nearly parallel to the spiral axis, and hydrogen bonds are formed between each carbonyl and imino group and an imino or carbonyl group of a residue nearly one turn forward or back along the spiral.

  One of these spirals is the three-residue spiral, in which there are about 3.7 residues per turn and each residue is hydrogen-bonded to the third residue from it in each direction along the chain. The unit translation per residue is 1.47 Å. There is evidence that indicates strongly that this configuration is present in alpha-keratin, contracted myosin, and some other fibrous proteins and also in hemoglobin and other globular proteins.

  The second hydrogen-bonded spiral is the five residue spiral, in which there are about 5.1 residues per turn and each residue is hydrogen-bonded to the fifth residue from it in each direction. The unit translation is 0.96 Å. We believe that this spiral is present in supercontracted keratin, which is formed from alpha-keratin with a shrinkage of about 35% in the fiber direction.

  We are indebted to Dr. H. R. Branson and S. Weinbaum for assistance. Our work has been aided by grants from the Rockefeller Foundation and the National Foundation for Infantile Paralysis. A detailed account of the work will be published soon.

  Linus Pauling, Robert B. Corey

  Footnote to be added at end of third paragraph: *A three-residue spiral described by Huggins (Chem. Rev. 32, 211 (1943)) is similar to ours, but differs from it in essential structural details.

  Dr. Charles D. Coryell

  Department of Chemistry

  Massachusetts Institute of Technology

  Cambridge 39, Massachusetts

  Dear Charles:

  I am very glad to have your letter of October 10. However, I am sorry to say that I am not coming to the gelatin symposium on October 19, and also am not coming to give the lecture in December. My trip in December was to have been to attend a meeting of the Advisory Committee of the Massachusetts General Hospital. Then, the date was changed from the scheduled date, to a time when I could not come.

  I am glad to learn that you are writing up some of the unpublished work on hemoglobin, and that you are to get out a paper in this field. I am sending you reprints of my two recent hemoglobin papers - I don't believe that I have sent them to you before - and also a reprint of the sickle cell anemia paper. I shall look forward to reading about your new theory, and shall let you know what I think. You probably know Robert St. George. He is now carrying out some experiments to test an idea of nine, that the heme-heme interactions are due to steric effects.

  We have thought about the action that you suggest, the preparation of a report on the Weinbaum case; but we are handicapped by the fact that we are all busy, and that no one of us attended all of the court sessions. I did not attend any of them - I was out of town, except for the last day. The feeling of the people who attended the trial was in general that Margolis had done a good job. Of course, if the money could have been raised earlier, it might have been possible for Sidney to get another attorney. As it was, he had to take the one who was willing to serve even when there was a chance that he would not even receive expenses.

  An effort was made to appeal Sidney's case, but the appeal court refused to allow him to be out on bail during the appeal* Since it would have taken about a year to appeal, and would have cost about $3,000 (expenses, not Including lawyer's fees), which was not available, the decision was made not to appeal.

  Brunner is now out on bail. His appeal case will come up

  Dr. Coryell

  In a few months. In normal times I suppose that it would be decided that the judge did take unconstitutional action, but under present circumstances it might well be decided by an appeal court which refused Sidney to be out on bail that the action was in fact constitutional. Brunner now has a job doing radio repair work, and he seems to doubt that he will be able to get back into chemistry and physics again.

  With best regards, I am

  Sincerely yours,

  Linus Pauling:W

  Research and Control

  The Lilly Research Laboratories

  Eli Lilly and Company

  Indianapolis 6, Indiana

  Dear Dr. Kleiderer:

  I am sorry to learn from your letter of October 16 that the decision has been, made to cancel the consultant arrangement with me.

  I am writing to say that I have enjoyed the intercourse that I have had with the Lilly Research Laboratories during the past four and a half years very much. I have learned a great deal from you and your colleagues. It seems to me that you have a very fine group of men on your staff, and it has been a pleasure to be associated with you.

  I want also to say that I have a very high opinion of the Lilly Research Laboratories and of Eli Lilly and Company. Although I do not know nearly so much about other firms as about yours, I cannot help feeling that I have had the good fortune of being associated with the best one.

  You probably know that I felt rather hesitant about entering into the consultant arrangement with the Lilly Laboratories four and a half years ago. I had not been associated with any company for a good many years, and I was afraid that the consultant arrangement might in some way interfere with my academic work and with what I consider my primary function in life, the discovery of new information about the world in which we live. It has been a source of satisfaction to me that my fears turned out to be without basis. My only worries about the consultant arrangement have resulted from a feeling that I might not be making a very significant contribution to your activities.

  I want to say that I shall keep confidential all information that I have about Eli Lilly and Company. In particular, I do not propose to become associated with any other pharmaceutical house in the foreseeable future.

  Sincerely yours,

  Linus Pauling:W

  Interviews with United Press and Associated Press

  Today I talked with Miss Clary of United Press, Richmond 6565, and with Mr. Arthur, of Associated Press, Richmond 7-9595• Miss Clary told me that a new story had come over the United Press wires, in which my name was mentioned. She said that Senator McCarthy had issued a statement in which the names of 9 atomic scientists were given, as examples of flagrant dereliction on the part of the Atomic Energy Commission. I said to her "I have never received any classified information of any sort about atomic energy from the Atomic Energy Commission." She said that the story also mentioned that I was connected with the Guggen— heim foundation, and that the Guggenheim Foundation had a flagrant record of giving fellowships to Communists. I said that I did not want to comment on this item, because I was only a member of the Committee of Selection of the Guggenheim Foundation, and could not speak for the Foundation.

  Mr. Arthur (perhaps he is at the city desk of the Los Angeles Times) seems to have a somewhat different story. He read the Associated Press story to me - I believe in toto. As read to me, the story said that the American Association for the Advancement of Science had Kirtley Mather as president, although he belonged to 40 Communist-front organizations. It mentioned the Federation of Atomic Scientists, and said that Higginbotham and Lyle Borst of the Long Island AEC laboratories were connected with it. He mentioned Philip Morrison and H.C. Urey, and then Linus Carl Pauling, who worked for Communist causes. I gave him the following statement: "I have been working in support of an international policy that would lead to peace, and I presume that that is what Senator McCarthy is referring to."

  MEMORANDOM TO: Peter J. Pauling FROM: Linus Pauling

  SUBJECT: Proposed Investigations

  I think on reconsideration that it might well be worth while to do some more work on hexagonal (NaCd6?) (I shall call it by this formula even though the composition is uncertain).

  I believe that it would be good to complete the formal investigation, even there is no chance of making a complete structure determination, unless some new structural information permitting a structure to be predicted comes to hand.

  The first thing to be done is to take the rotation photograph that David Shoemaker has, and to measure it carefully, the measurement should be done, with the comparator, by measuring the vertical distance between two corresponding spots above and below the equator. The measurement should be made for a pair of spots on the left side of the film, and the corresponding pair of spots on the right side of the film, and the average of the two taken, to correct for possible errors due to mis-alignment of the crystal. The measurements should be made for all the pairs of spots that you can see, with a notation made as to which spots look clear and sharp, and which are the harder to measure. The latter should he included in the final average only with a decreased weight.

  After the distance between spots has been measured, and the layer-line numbers have been assigned to them, a calculation should be made of the value of B(subscript)O, the identity distance along the axis of rotation. This calculation should be made by the formula S(lambda)= i sin n, in which n is the angle between the plane of the equator and the plane of the cone containing the diffracted beam, and 1 is equal to B(subscript)0, the orthohexagenal B axis. I think that the information about the wavelengths and effective radius of the camera probably would permit the value obtained for B(subscript)0 to be good to somewhat better than 0.l%.

  Next, the value of the axial ratio of the crystal should be obtained from the Laue photograph. You saw how this was done by measurement of the distance between the lines drawn on the gnomonic projection. A better way of doing the job is to measure the distance on the Laue negative between a spot and the diametrically opposed spot. This measurement should be made for the three or six pairs of equivalent spots constituting a (c?)one, and the average taken. The tangent of the angle, which is equal to the ratio of this distance to 10 (twice the plate distance in the Laue photograph), is also equal to the ratio of Co:Bo, multiplied by an appropriate ratio, which can be found from the assignment of indices to the spots. This gives then a value of Co.

  Next, the Laue photograph should be examined carefully, in order to see whether there are any reflections incompatible with the unit with a0-21.6 A(Angstrom) and c0 - 9.6 A (Angstrom) (approximately). This can be done by calculating the value of sin (theta) between which reflections should have l = 1 and n(lambda) in the range 0.24 to 0.48. The reflections with l = 1 lie on the points of the reciprocal lattice, that is, the intersections of the sets of lines that were being drawn today. Similarly the values of sin (theta) within which reflections with S = 2 should lie can be calculated, and these reflections should be looked for, in order to see whether any of them occur with sin (theta) values less than the minimum. The gnomonic poles of these reflections lie at points with coordinates 1/2 on the gnomonic net.

  In the same way spots with s=3 should be searched for, to check whether every one of them is in the right region. I think that the only remaining work to be done on the Laue photograph would be the examination of the photograph to find absent reflections, permitting a statement to be made about the space group.

  I believe that a reasonably good estimate of atomic volume of sodium and cadmium in the crystal can be made, and that with the reasonably accurate values of the edges of the unit some statement might be possible about the composition. I believe that this work could be published, in the form of a brief note stating what had been done.

  Sun. nite

  Dear Mom,

  How are you? I am OK.

  On Friday I got the "Folkard" you mailed Halloween. On Friday (next) I will be at the airport with Pete to pick you up. The Chadwicks said I could come home on that weekend.

  I got my laundry done at the Coxes yesterday. Their washer does a wonderful job.

  This will be my next to the last letter. I will mail one Tues. (write it Mon. Evening) to you in care of Dr. David E. Green, 1702 University Avenue, Madison, Wis.

  This morning I put leaflets on peoples doorsteps advertising Esterman and Spears. (I was helping Chas Cox) While doing so I met I. H. Spears. He is running for #47 assembly. He is a negroe [sic] but that doesn't make any diff. I gotta go to Bed

  Love

  Crellie
