  Copy of report filed under "PROGRESS OF RESEARCH REPORTS"

  April 5, 1939

  Dr. Irvin Stewart, Director

  Committee on Scientific Aids to Learning

  41 East 42nd Street

  New York, New York

  During the past few months the situation with respect to the Fourier Calculator which we hope to construct has changed greatly. The plans initially made for a Fourier Synthesizer of rather conventional design were unsatisfactory, as pointed out by Dr. Fry.

  About two months ago Dr. C. A. Beevers, of Liverpool, wrote to us suggesting that a Fourier Calculator could be designed for crystal structure use along the lines of the Beevers-Lipson strips, which are now being used successfully here and in other laboratories. Mr. Philip A. Shaffer has acted on this suggestion and has made a preliminary design of a Fourier Calculator of the new type, described on the accompanying pages. This calculator seems to be extremely promising. We had estimated that a two-dimensional Fourier synthesis, which now requires from four days to a week for its calculation with use of the Beevers-Lipson strips, could be carried out with a harmonic synthesizer drawing curves in from twelve to sixteen hours. The new Fourier Calculator would, it is estimated, turn out the same job in from one to two hours, an improvement over present methods by a factor of about 50. This improvement in the crystal structure technique should be of extremely great value, permitting an attack to be made on crystals of highly complex structure, such as those of proteins and other substances of biological importance.

  Since Mr. Shaffer has not had experience in instrument design, we have made arrangements with the Observatory Council of California Institute for an expert instrument designer, Mr. Michael Karelits, to devote part of his time to the detailed design of the Fourier Calculator this Spring.

  [page 2]

  Mr. Karelitz is employed permanently as an instrument designer in connection with the construction of instruments for use with the 200 inch telescope at Mt. Palomar. I believe that we can be sure that a satisfactory detailed design of the instrument will be prepared under Mr. Karelitz's direction. The designing process is now well under way, and we expect the design to be completed within two months.

  I should like very much to have the construction of the Fourier Calculator begun immediately on completion of the design and completed if possible during the summer. Mr. Karelitz estimates that the cost of construction will be about $2000, aside from the cost of the design. From previous experience with the construction of apparatus, I would expect that the machine might accordingly cost between $2000 and $2500. Our research funds permit us to bear the cost of the design and a portion of the cost of construction, but not the entire cost.

  I accordingly apply to your Committee for a grant of $2000 to be used for the construction of a Fourier Calculator for use in connection with the determination of the structure of crystals by x-ray methods.

  I wish again to point out that this calculator would be used very extensively. There are in these Laboratories at present three staff members (Pauling, Sturdivant, Helmholz), four post-Ph.D. fellows (Corey, Hughes, Levy, Weinbaum), and several graduate students devoting their research efforts largely to crystal structure work.

  Respectfully yours,

  Linus Pauling

  Dear Alex:

  After we had decided definitely to come to Europe this summer, the political situation made such progress in the wrong direction that we have decided to remain undecided for a while. Perhaps Hitler's address scheduled for day after tomorrow will be sufficiently significant in one way or the other to make up our minds for us. If we do come, we shall arrive in England early in July, and we are looking forward to seeing you and Alison.

  We moved into our new house on March 10, Linus' birthday, and, although we are not yet settled there, we have been very happy. The children enjoy especially the freedom of life in the country, and they seem to be happier than ever before. I have been very pleased to have a pleasant study in which to work, as well as to admire the views, and I have spent more time at home than formerly. Ava Helen and I are driving up to Deep Springs and to Berkeley over the weekend, starting tomorrow. It has been a year and a half since I have gone to Berkeley, and I am looking forward to seeing what G.N. Lewis's men have under way.

  I wish to thank you for your words about Zechmeister. I understand that he is troubled by the political situation in Hungary, and has been considering the question of leaving the country. We have not made any definite decision regarding another appointment in organic chemistry here.

  Niemann seems to be getting along very well--he has done a fine job in outfitting the laboratory this year. No matter what addition to the staff is made, Niemann will retain complete freedom for carrying on his own work, as you advised.

  With best regards, I am

  Sincerely yours,

  LP.jr

  Dear Thorfin:

  I am sorry that I have delayed so long in writing you about your manuscript, which I am returning enclosed. I found the manuscript very interesting, and Drs. Coryell and Davies have also read it and made some suggestions. I forgot that you would return to Chicago from the Baltimore meeting before the boys who went to Baltimore from here would get hack, and so I delayed overly long in writing to you.

  Your results are extremely interesting and I think that the change in the values of the interaction with change in salt concentration is especially interesting and difficult to interpret.

  Coryell, Dodson, and I have sent some time ago a paper to the Journal of Physical Chemistry on hemoglobin in which there is a re-derivation of the oxygen equilibrium expression. This was accompanied by another paper by Coryell in which he discussed the use of Hill's equation and the value of Hill's n in determining the value of α from empirical data. I am enclosing a letter from Coryell in which he makes some remarks about your paper. The remark about one acid group rather than two per heme needs some explanation. In ay paper on oxygen equilibrium of hemoglobin I said that the experimental data did not fit the theoretical equation for one acid group per heme but did fit that for two acid groups per heme. Coryell discovered some time ago that actually both equations fit about equally well, and that I must have made a numerical error when I was trying to apply the one acid group equation.

  Professor T. R. Hogness -2- Aprll 26, 1939

  It seems probable that there is only one acid group per heme effective in this particular pH range.

  Ava Helen and I are planning to be in Chicago from June 24th on for a few days, at the time of your symposium and we are looking forward to seeing you then.

  With best regards, I am

  Sincerely yours,

  Linus Pauling
