  March 1, 1939

  To: Professor Millikan

  From: Professor Pauling

  Dear Professor Millikan:

  Professor Szent-Györgyi is a very distinguished man, having received the Nobel Prize for his work on vitamin C. It is our feeling that there is not a great chance that we would want to offer him a position in the Department, since his field of interest is really biochemical rather than organic. I understand, however, that he is considered to be a very interesting man and an unusually good lecturer and I think that it would be wise in connection with our policy of building up this field to extend this invitation to him. I hope that you can approve this expenditure from the Rockefeller Fund. I have already discussed the matter with Mr. Barrett.

  Mr. W. S. Schaefer

  Cornell University Press

  124 Roberts Place

  Ithaca, New York

  Dear Mr. Schaefer:

  I am getting worried about the delay in arrival of page proof. It has been two weeks now since the first eighty page batch of page proof arrived. Dr. Hughes tells me that all of the page proof for the Bragg book reached him in a period of three weeks, and I have been hoping that the paging of my book would proceed just as quickly since I am, as you know, being inconvenienced this year in teaching my class here because of lack of the book. Would you let me know how much further delay in the manufacture of the book I should expect?

  Sincerely yours,

  Linus Pauling

  Dear Tom,

  I haven't learned of any permanent position recently to refer you to, but I have you down on ay list and shall centime to he on the lookout. I was glad to receive your letter and learn some news about you, Lassettre, and Harker.

  Niemann and I have just about finished preparing a criticism of the cyclol theory, and we hope that the J.A.C.S. will publish it. The x-ray results aren't any good, and we have examined all of the other arguments and decided that no proteins have a cyclol structure.

  There is a lot of activity in the laboratory with several people visiting here from outside, including Professor Hassel and Dr. Finbak of the University of Oslo. The x-ray work going on is largely on complex organic substances such as amino acids, and Dr. Corey is working on oxyhemoglobin and other proteins.

  I am just finishing reading proof of my book on the chemical bond, which will, I hope, be out shortly.

  With best regards, I am

  Sincerely yours,

  Dear Dr. Schoenflies:

  I have been making an effort to arrange for you and your family to be brought to Pasadena in order that you might continue your chemical studies at the California Institute of Technology. I have found, unfortunately, that the committees which have been set up in this country to deal with these cases act very slowly, and it has not yet been possible to make these arrangements. I am continuing at work, however, and hope to write to you again soon about the matter. In the meantime, I should be glad to know if your situation has changed.

  Mr. William C. Boyd

  Associate Professor of Biochemistry

  Boston University School of Medicine

  80 East Concord Street

  Boston, Massachusetts

  Dear Professor Boyd:

  I don't know of any simple discussion of symmetry numbers in the literature. Those numbers enter in the statistical mechanical discussion of the thermodynamic properties of molecules, and they are referred to in the standard texts on statistical mechanics, but the discussions that I have found are far from clear. I think that if you could go over to the Harvard Chemical Laboratories and talk a few minutes with E. B. Wilson, Jr. or Kistiakowsky you could get the point straightened out. The symmetry number of a molecule is the number of ways in which the molecule can be brought into a given configuration by rotation. For example, a molecule of chloroform has symmetry number 3 corresponding to rotation around its three-fold axis. The symmetry number comes into thermodynamic calculations in a way such as the following: with four hemes in the corners of a square, the first oxygen molecule to attach itself to hemoglobin has a choice of four positions, corresponding to the symmetry number 4 for hemoglobin. Consequently we can see why the symmetry number 4 should introduce the equilibrium constant, as compared with the constant for attaching an oxygen molecule to a given heme.

  I think that symmetry numbers first came into the chemical literature about twenty-five years ago, when E. Q. Adams and Bjerrum independently derived the factor k for the first and second acid constants of a dibasic acid with acid groups far removed from one another. This factor 4 results from the symmetry number 2 for the acid HA---AH entering in one direction and that for the ion A- --- A- entering in the other direction.

  Sincerely yours,

  Linus Pauling
