  Dear Professor Pauling,

  I was pleased to learn that the British were not actually starving you. We have been very well off indeed and much healthier than in Pasadena except for bad colds at Christmas time when they didn't heat our flat. The only significant food restriction is meat which has been reduced to 50 grams a day, perhaps a vast quantity by British standards. An American friend of ours just returned from Finland where he was hungry all the time though the natives didn't seem malnourished. He said most of the people were quite openly and insultinlgly [sic] against the Russians.

  I think this has been a very profitable year, particularly in broadening my viewpoint and interests. From a purely scientific point of view I could prabably [sic] have learned as much or more in America. The most interesting fact discovered so far is that the sample of serum albumin brought from Pasadena denatures from ten to thirty times as fast as the local product, depending on how the denaturation is measured. I don't know why this is so. Stig Claesson is convinced he can measure molecular weights up to 5,000 by isothermal distillations between samples in a closed and evacuated vessel in a manner similar to that used for getting activities of salt solutions. He showed me his apparatus and it looked very pretty in any event, all copper and silver.

  Professor Tiselius has offered me an attractive job for the winter '49-50, possibly on the adsorption analysis of proteins and protein hydrolysates if their present experiments along these lines work out satisfactorily. Though I have tentatively accepted this offer, plans so far in the future are subject to change. I do not know, for one thing, what effect, if any, this would have on my standing at Caltech. In any event my wife will probably stay here another year with the children.

  This summer we will try to see a little of some other parts of Sweden. I don't expect to see much of continental Europe but will surely visit Denmark and will try to see something of either France or England if I can get a reservation on the Cunard line. I will get back some time in September depending on which of several applications for a reservation comes through.

  Sincerely yours,

  [Stanley Swingle]

  Dear Holmes:

  I enclose some material about Unicam instruments, with the suggestion that you order an apparatus immediately, in case that one of the Unicam instruments has not already been ordered. I think that it could be paid for from any suitable fund, including the Rockefeller Fund.

  It might well be that two of the instruments should be ordered, such as the single crystal goniometer and the two crystal goniometer.

  I feel that it is important that we increase the facilities for x-ray photography at the institute. I was very much interested to see what they have in the x-ray lab at the Cavendish Laboratory, where H. B. Taylor is in charge. They have in one room, about 50% larger than our x-ray lab, a number of transformers and x-ray tubes, with associated apparatus. The total number of "windows" in this lab is 25—-most of the tubes have two windows, one on each of two sides, and in general they seem to operate two tubes from the same transformer. There is a bank of six transformers with controls down the center of the room, with an x-ray tube on each of two sides of each transformer, and an apparatus on each side of each x-ray tube. This gives 24 windows—I don't know where the 25th is. In addition they have a teaching laboratory with four windows, which is used only one term in the year for teaching, and is available for research the rest of the time. They use the multiple film technique for intensities, and seem to have some sort of photometric method of obtaining intensities, without, however, doing much in the way of integrating over the spot.

  I must say that I think that there is one advantage to the English system, which is that research men are supposed to devote all of their time to research, rather than only half time or less. They do attend a few lectures, but not very many. It seems to me that perhaps we should revise our system somewhat, and have our graduate students take class work completely during the first year, and then practically 100% research during the other two years. The disadvantage to this is, of course, that we do not find out whether the man has any research ability during his first year.

  Prof. Sturdivant May 4, 1948

  They have been doing some interesting jobs at Cambridge. Two of the pyrimidine structures, that I saw last summer under way, are described in the first issue of Acta Crystallographica. They are finishing up a purine now. Corey would be interested to know that this work on pyrimidines and purines is designed as a start in an attack on nucleic acids. Also a girl there, Mrs. Douglas, has just finished determining the structure of a complicated intermetallic compound, Co2Al9, which has monoclinic symmetry. There are a number of other representatives of this structure. She is also beginning work on MnAl6. Their general program is to tackle the compounds of aluminum and the iron-group transition elements. In addition they have made some studies of the sigma-phase of chromium and iron, containing 50% of each of these two elements. This phase is a complicated powder diagram, which is, however, closely related to the body-centered structure. Instead of the successive lines of the body-centered structure, there is, in the general neighborhood of each of these lines, a complex of a half-dozen or more lines. They have not yet found out what the unit of structure is for this sigma phase. The single crystals of Co2Al9 and MnAl6, that they use are made by an interesting method, of annealing the an alloy with an excess of aluminum or cobalt--I am not sure which--and then subjecting the sample to electrolytic etching until the phase that is the more readily attacked is dissolved away, leaving a pile of crystals of the other phase. These crystals are perhaps two- or three- or four-tenths of a millimeter in two directions, and several millimeters along the needle axis.

  There are three men working with Taylor on the structure of feldspar. They find, for example, that the first feldspars give rotation photographs corresponding to the normal feldspar structure, but with faint extra layer lines in between the strong layer lines. These faint layer lines indicate a unit either five times or seven times longer in the direction of the axis of rotation. Moreover, the two extra layer lines that are nearest to half-way between the main layer lines are strong, the others being very weak. This indicates an approximate doubling of the c axis. The explanation presumably is that the two kinds of feldspar structure, say a and b, tend to repeat, but not exactly, the sequences being ababa ababa or abababa abababa. It is clear that many interesting things remain to be done in this field. The difficulty in this feldspar work is that it is almost impossible to obtain single crystals of the micro-type feldspars that they are studying, the ordinary apparent single crystals being complex twins. The girl who has been making these photographs has taken an apparent single crystal, made x-ray photographs of it (Laue photographs), chipped off a piece, repeated the x-ray photographs, and continued until she obtained a small piece that gave a simple Laue diagram.

  Prof. Sturdivant May 4, 1948

  The piece that she obtained was about 0.02 X 0.02 X 0.01 millimeters, and yet they have used it to get first-rate rotation and Weissenberg photographs.

  I am looking forward to getting back, and to talking with you about the x-ray work. I hope that you aren't working too hard now.

  Sincerely yours,

  Linus Pauling:par

  Dear Fred:

  I have decided that I shall have to write to you without having your letter before me. When it arrived I read it, and then tucked it away somewhere— so well that I haven't been able to find it again.

  The results that you have got look very good to me. Have I told you that I found it possible to develop a resonating-valance-bond theory of metals, making use of two-electron-bond functions multiplied by suitable Bloch factors, that lead to the same qualitative aspects of the Brillouin zones as the ordinary one-electron molecular-orbital theory, and with the same electron numbers in the Brillouin polyhedra?

  I trust that you are going ahead with the evaluation of the electron numbers for important Brillouin zones for various crystals. I am sure that the new results that you mention in your letter plus other similar ones that you probably will have before long will be worth publication.

  I would, by the way, like to know what the various interatomic distances are in NaZn13 and other compounds with that structure, in order to check up on the question of the importance of half-bonds, one-third-bonds, etc. Could you make these calculations and send the results to me? You might think it worthwhile to look over the interatomic distances in all of the crystals for which you make Brillouin polyhedron calculations, to see if you find anything new. One troublesome point is, of course, the fact that a difference in hybridization (amount of d character) causes the single bond radii of an atom to be different for its different bonds.

  I am not sure that it will be possible for me to send a paper to you for the first issue, that is, a paper of which I am author or co-author. I am very busy, with a number of jobs to get done before leaving for Europe. I believe that I have arranged for two papers from this laboratory to be sent to you, one by Professor Verner Schomaker on the use of punched cards and one by Mr. A. M. Soldate, on the structure of the intermetallic compound FeSi. I have just been talking with Dr. F. J. Ewing about the possibility that he and I could prepare in the near future a brief article on some phase of the structure of metals and intermetallic compounds which would be suitable for the Acta Crystallographica. There is the possibility that we can do this, and if it can be done we shall send you the manuscript as soon as it is ready.

  [page 2]

  By the way, I think that we should do something toward improving the nomenclature. For example, coordination number is an awkward end unwieldy expression— we need one short, precise word for this concept. Perhaps ligancy could be used. It would fit in well with ligand and the verb to ligate. We also need some general words to express the bonds between one atom and the surrounding atoms—we now use the word bond to refer both to the electron pair bond that is resonating around among altar-native positions and to the fraction of an electron pair bond that is a portion to a particular position. I have also felt troubled about using the word position in this way—to mean the region between two atoms. If we do introduce any change in nomenclature, it must be very well thought out, and must not involve too great a strain on the memory, or too great a departure from the past.

  Our trip to Paris went off well, and after our return (the three children were there with us) Ava Helen and I had a week in Scotland and northern England, during which we combined sight-seeing with lecturing. Now, after the first two weeks of the spring term here at Oxford, the three of us {including Peter) have taken a four-day automobile trip—to Cambridge, Peterborough, Nottingham, Manchester, Chester, Shrewsbury, and back to Oxford.

  With best wishes, I am

  Sincerely yours,

  Linus Pauling:par

  Dear Linus,

  Dr. Pomerat and I have just returned from a couple of days at Oxford. You will doubtless hear that we were there, and I don't want you to think we failed, from carelessness or lack of interest, to look you up.

  Actually we deliberately avoided you! I hear on all sides that you are working too hard; we had no specific or pressing business with you; and I refuse to complicate your life further and unnecessarily. So just take this note as proof that you were not forgotten.

  Cordially,

  Warren Weaver

  Dr. Warren Weaver

  The Rockefeller Foundation

  56, Curzon street

  London, W. l

  Dear Warren:

  I was glad to receive your letter—although it doesn't take the place of seeing you.

  As to my working too hard, I still have a few speaking engagements to be filled, but then there is a good stretch when my time will be free. Part of my trouble, of course, is due to the fact that I am deeply interested in my new theory of metals, and I want to get the consequences of the new idea worked out before I get back to Pasadena and start in again on biological things. My lectures this term are on intermolecular forces and biological specificity, but I have been devoting my research time to metals.

  It is fine that The Foundation has made the new grant to us—I am sure that something well worth while will come of it.

  Cordially yours,

  Linus Pauling:par
