  August 2, 1943

  To: Dr. D. Pressman

  From: Dr. L. Pauling

  I believe that it would be worth while to have another experiment run with the hapten R'X' in order to see whether or not the predicted effect of a difference in the two kinds of haptens when one antiserum is present in excess can be detected. I suggest that you use the mixture anti-R serum and anti-X serum in the ration 93:7, corresponding to your 12.8:1 mixture. I suggest that three series of experiments with this ration be carried through, one with 10 x 10^-9 mols of R'X' antigen, one with 100 x 10^-9, and one with 1000 x 10^-9. Each of these should give approximately 60 micrograms of precipitated antibody. It will be necessary to go to considerably lower hapten concentration than you used before. I suggest that you start , or end, with an amount of hapten considerably less than the amount of antigen. The maximum amount of hapten should be about the same as in the experiments carried out. If it would not make too many tubes, perhaps two-fold dilutions should be used, although I think that three-fold dilutions might be satisfactory. If three-fold dilutions are used, four of the tubes should correspond to those analyses already made.

  Do the numbers 10^-3 and so on down for the hapten given on the sheet you turned over to me represent grams or moles of hapten?

  I should like you to calculate three more curves for Figure 2, corresponding to B' = 20, 15, and 5, with B'' = 30, 35, and 45. Also on Figure 3 I should like four more curves calculated, those for total antigen = 20 and 80, respectively.

  August 14, 1943

  Mr. Karl G. Jansky

  Bell Telephone Laboratories

  463 West Street

  New York, New York

  Dear Mr. Jansky:

  I am pleased to tell you about the treatment which I have received for Bright's disease. I am enthusiastic about the progress which I have made, and I think that the treatment which I have received may well be the best one available.

  I learned that I had Bright's disease while in New York, in March, 1941. Because pronounced edema showed that something was wrong, I went to the Rockefeller Institute for Medical Research, where my trouble was diagnosed as Bright's disease. I was recommended to see Dr. T. Addis, Professor of Medicine at the Stanford Medial School, Clay and Webster Streets, San Francisco, California, who has conducted a clinic on Bright's disease for about twenty-five years. I came home, and for about two or three weeks adhered to a regimen given to me by Dr. Addis by telephone, and then went to San Francisco to see him. After about four months on a minimum-protein diet I became free of edema, which had amounted to about twenty-five pounds. Since then I have adhered to a minimum-protein diet, and have been restored to good health; protein urea remains, but is now about one-fifth what it was two years ago, being now three grams per day.

  The principle of Dr. Addis'es [sic] treatment is that the work done by the kidney should be minimized. In addition he abolishes meat, fish, and fowl from the diet, since there is some evidence that substances in these materials are harmful. The main way of minimizing the work of the kidney is to keep the output of urea a minimum, which is achieved by having the protein intake as small as is consistent with good health; in my case this is 47 grams per day. Increase in urine volume, by drinking more water, is also helpful. Salt intake, after edema is absent, should be normal. In my case urine volume is about 3 liters and salt 12 or 15 grams per day.

  I like Dr. Addis'es [sic] treatment because it seems to be reasonable, and because he seems to have had success with it over a long period of years. This has been recognized in various ways; he was given the Cullen prize by the Edinburgh College of Physicians and Surgeons, and last year he was brought east by the Commonwealth Fund to lecture about his work at the Brooklyn School of Medicine and elsewhere.

  I would be glad to give you any other information that I can.

  Sincerely yours,

  Linus Pauling

  Dr. Robert Loeb

  College of Physicians and Surgeons

  620 West 168th Street

  New York, New York

  Dear Dr. Loeb:

  Today Dr. Campbell and I had the pleasure of a visit from Dr. Gregersen, who probably was steered this way by you. We have had an interesting discussion with him.

  A few days ago we sent several samples of our preparations of oxypolygel to Dr. Luck. Today a letter came from him, in which he says that he is not able to carry on any molecular weight determinations, and that he does not have a centrifuge with which to do the work.

  I feel that studies with the ultracentrifuge are needed, and I hope that you will tell me that it would be all right for us to send a number of samples to Williams or to Cohn's laboratory. We sent a couple of samples to Williams, and received a brief report on one of them.

  It looks as though our method of preparation is not well enough standardized to give a uniform product—the osmotic pressure varies from preparation to preparation. With some evidence from the ultracentrifuge as to how the distribution in molecular weight is changing, we should be able to improve the method.

  With best regards, I am

  Sincerely yours,

  Linus Pauling

  August 30, 1943

  Mr. H. H. Windsor, Jr.

  Editor, Popular Mechanics Magazine

  200 East Ontario Street

  Chicago, Illinois

  Dear Sir:

  I happened to see a copy of the July issue of Popular Mechanics Magazine, and to read an article entitled "Uncle Sam Picks an All-Star Team" by Wayne Whittaker, in which there is reproduced a test, labeled "Copyright, The Psychological Corporation", which is said to be similar to tests used by the Amy. On pages 52, 53, and 54 of the Magazine there are given twelve questions with accompanying drawings, with the answers given on page 146. I am shocked by the fact that three of the twelve answers are wrong, and I am writing to find out if there is any excuse for this. In particular, I hope that you can assure me that this particular test is not used by the Army— I hope very much that the able young men taking Army tests are not handicapped by having their examiners so lacking in ability as to assign incorrect answers to twenty-five per cent of the questions.

  The three questions for which incorrect answers are given are Numbers 3, 4, and 6.

  No. 3 shows a drawing of a glass of water with chunks of ice floating at the top of the water. The question asks at which point is the water colder, with reference to a point A about an inch below the ice and a point B at the bottom of the glass. The answer is given as A. However, if the water is above 4º C, convection currents will cause the cold water immediately about the ice to flow to the bottom of the glass, which will fill with cold water at 4º C from the bottom up; hence under these conditions point B will be colder than point A. When the water throughout the lower part of the glass reaches the temperature 4° C the two points will be at the same temperature, and only at overall temperatures less than 4° C will point A be colder than point B.

  The fourth question relates to a drawing of a uniformly filled freight car on a slanting track, and pushing against the bumper; the question asks which wheel presses down harder on the rail, and the answer is given as A, which is the wheel nearer the bumper. However, it is easily shown by resolution of the force of gravity acting on the center of mass of the freight car into two components, one parallel to and one perpendicular to the rail, that both pairs of wheels press down equally hard on the rail. Hence the wrong answer is given to this question.

  The sixth question shows two balloons, one round and one elongated, and asks if the balloons weigh the same and contain the same volume of gas, which one will float higher in the air. The answer is given as A, the elongated balloon. The correct answer is that the two balloons, which weigh the same and contain the same volume of gas, would float equally high in the air. If the question were phrased to ask which balloon would rise the more rapidly, the answer would be balloon B, since an elongated balloon mowing in a direction perpendicular to the direction of elongation would show more frictional resistance than a round balloon. Hence no matter which interpretation is given to the question, the answer as given is wrong.

  I shall be pleased to have you tell me why such a simple set of questions should have twenty-five per cent of the answers incorrectly given.

  I should like to keep a copy of this issue of the magazine for reference. Will you please have the Circulation Department send me a copy of the July 1943 issue, and I shall send the money for it.

  Very truly yours,

  Linus Pauling
