  Dear Professor Pauling,

  Thank you for your letter of January 29 concerning the form factor for the 7-strand cable. Under separate cover I am sending you and Professor Corey reprints of the work of Dr. D. P. Riley and myself which are relevent to this problem.

  I do not feel that the equatorial spacings will be markedly altered whether one assumes 7 parallel rods or whether one assumes 6 rods twisted with mild pitch about a central rod.

  The difference in your form factor for the equatorial spacings for your seven strand cable and that for the 7 parallel rods case Riley and I have used, comes about in the averaging process. We assumed that the 7 rod case can rotate.

  In the end, experiments will, of course, prove which model is correct. It is for that reason that I am planning to do some low angle scattering to obtain equatorial spacings for wool in the α state. A student of mine is in the process of isolating the spindles of the cortex of wool since we would like a "pure" wool diagram un-obscured by the scales and cementing material of the wool fibers.

  Incidentally, another student of mine has crystallized insulin which has been iodinated to the extent of 15% by weight in iodine. This material should be of interest since the scattering by the iodine exceeds that of the whole protein itself.

  As you will see from our nucleic acid work, we considered a helical model, however, parameters can so be chosen as to fit any date. Hence, we were satisfied to choose the rod model which, at least, can be discussed more uniquely in terms of our data. Riley and I found, experimentally, a spacing of 16Ǻ for the unhydrated nucleic acid molecule but the value is based on an extrapolation of our observed data and hence may be in error.

  Professor Pauling -2- February 3, 1953

  I am not at the present time working with the X-ray diffraction of nucleic acid. Curiously enough, my main interest these days is in the photochemistry of dyes in solution in an optimistic attempt to explain certain biological phenomena such as vision. My work may never help to explain these phenomena but the photochemical properties of dyes in solution are themselves fascinating.

  Sincerely yours,

  Gerald Oster

  Dear Mamma and Daddy,

  I received two very nice letters from you separately. I apologize, Mamma for the crack about Trevelyan; I can remember writing it and thinking this is rather poor to say.

  I had, as you know, decided not to go to Greece, for a number of reasons; cost, too short a time for visit, too long a time for work here, too cold now. However, i had talked to Joy Jonekheere ne Pickard about it and on the evening of the 16^th she rang me and said I should ring you and go. I would never get another chance, etc. etc. So, I got a reservation on a plane for the 18^th, paying first class fare as a student travelling between school and his parents. My tutor, Mr Pringle, signed the request for this concession*. The plane was delayed until 7 a.m. (22hr delay) on the 19^th, and I arrived in Athens about 5:30 p.m. on the 19^th. I was rather upset when you were not in the hotel, and I thought your plane had been delayed by bad weather, so I checked daily with all airlines. Rather stupid of me as it took three days to dawn on me that you would never come. It did not occur to me that you were still in the U.S. I thought you were probably in Spain or Italy. It was warm in Italy (at least that week) and cold in Greece. I was a little numbed by this change of fortune and for the first week did nothing except wander in the streets, and visit the open antiquities. I settled into a pleasant and reasonable pension, and after the first week awakened to the situation and got to work. I read a good deal during that time. Anyway, then I started several trips, actually three. Going first to Delphi for a day, and then to the Peloponissas for about four, visiting Corinth, Argos, Mycenae, Nafplion, Epidauros. I then went to Crete on the boat and stayed three days, three nights I guess, but had to fly back to Athens. I stayed at Iraklion, and visited Kuossos, which is very close, and Pheistos, which is on the south side. I enjoyed Crete very much. I then came home. I received a letter Daddy wrote on the 14^th on the 28^th which was very funny. He said you trusted I was not on my way to Greece because you would not be there. The sort of humor that went with the situation.

  Except for being lonely, it was a wonderful trip. I learned a great deal and like Greece very much. It was rather cold and rainy, the sun shone about one third of the time. I had to buy some Greek boots and socks for my feet. Fortunately, I had taken some money and was quite comfortable. In general heated hotels and my heated Athenian pension.

  Christmas was spent in this pension and on the Acropolis. Lonely.

  I am very sorry I did not write you. The mail delivery to me was slow, and I just did not know where you were until after my return and a letter came on the 18^th saying where you would be in the future.

  Linie should think I went to Greece. I wrote them an air letter from Athens.

  My copy of the CIT P. Chem text, an orange book, was left in the library. Would you please send it? I shall treat your letter fully in a letter subsequent to this. Do you pay essentially 0.5 (list price) for technical and text books on an income tax consideration? American books are terribly expensive and even more so here. I think we can keep Linda in line. She can go three months or so around with me,- I hope to spend a month or six weeks in Naples and probably must go to the xtallography conference at the end of July. Then in the fall she can come to Cambridge, go to lectures, meet interesting people. Town is full of just such people. Jim Watson's sister was here for a while. She is my age.

  Much love,

  Peter

  Dear Peter:

  I am writing to tell you that we have found that the atomic coordinates inour nucleic acid structure need to be changed a bit. One of the van der Waals contacts is too close – between carbon atom 5’ and an inner oxygen atom of the phosphate group to which it is bonded. I judge that I overlooked this contact when I was making the final calculations – in the preliminary structure there were several van der Waals contacts that were pretty small, and I hunted around for parameters that would increase all of them until they were at least acceptable. Apparently I forgot to include this contact in the final process. It will be a few weeks before we have finished the job of checking over the parameters again, but I expect them to come out all right – at any rate I hope so.

  At the present time I have reservations to leave New York on Thursday 2 April and arrive in London on Friday 3 April, and then to leave London on Monday 6 April. However, Bragg wrote that he and Lady Bragg were planning to go to Brussels on Tuesday 7 April, and I probably shall delay my trip for one day, thus arriving at London Airport on Saturday 4 April and leaving on Tuesday. Then I shall fly directly back to the United States after the Solvay Congress is over. I plan to meet Mama in New York. Then we shall stay for a few days in New Haven, where I am to give the Treat B. Johnson lectures, go to Philadelphia for the American Philosophical Society meeting, to Washington for the National Academy meeting, to Buffalo for a few days, where I shall give the Foster lectures, and then home.

  Let me say that we have enjoyed very much having the copies of the London Times and the New Statesman and Nation that you sent us. I hope that you will save up more, and send them to us.

  I think that I should get another Riley –essentially the same as the one that I have, but not in such bad shape. Do you think that we could save any money if you were to buy the Riley for me, in England, or should I approach International Motors and put in the order right away? I do not want you to buy it until summer time – anyway, you probably will be so busy with myoglobin that you wouldn’t have time to drive it around. Please let me know at once whether the plan for you to buy it for me is feasible. We are hoping to get on a freighter, probably in Scandinavia, about 20 August, to go by ship, with the car on the same ship, to the eastern United States, and then to drive home across the country. We are due in Tübingen on 8 July. We have a chemistry teachers workshop scheduled for Pasadena from 22 June to 29 June, and accordingly probably shall fly to England about 1 July. This means that we shall have to move right along to get to Tübingen. I hope that you are planning to make part of the journey with us.

  I am still working on the job of finishing up the new edition of GENERAL CHEMISTRY. I do not think that it is done perfectly, but it will be interesting to see whether the new chapters are useful in teaching our own freshmen.

  Love from

  [Linus Pauling]

• Letter from LP to Professor C.H. Best, University of Toronto. [Filed under LP Correspondence: Box #217, Folder #5 (Lippman)]

  4 February 1953

  Professor C.H. Best

  University of Toronto

  Toronto, Ontario

  Canada

  Dear Best:

  I am writing to ask for advice for a friend of mine who is interested in the possibility of coming to Canada, in order to carry on medical research.

  The man is Richard W. Lippman. I have known Dr. Lippman for six or seven years - I met him first when he was working in Dr. Thomas Addis's laboratory, in San Francisco, at a time when I was a patient of Dr. Addis. After Dr. Addis's death I have been a patient of Dr. Lippman. Dr. Lippman came to Los Angeles, and for several years operated a kidney clinic in the Cedars of Lebanon Hospital. At the same time he carried on research in the Cedars of Lebanon Institute for Medical Research, with Dr. Goldblatt. Then a year ago, in December 1951, Dr. Lippman and two other members of the staff of the Hospital were notified by the lay board that they were not being continued. It was pretty clear that this action was taken by the lay board because of political reasons, but no statement has ever been made by the board, and Dr. Lippman has not been allowed to discuss the matter with the board.

  The more recent history is that Dr. Lippman stayed on at the Cedars of Lebanon Institute for Medical Research for one year. This Institute has the same lay board as the hospital, but the director, Dr. Harry Goldblatt, has complete authority with respect to the staff. During the year, however, the board returned to the Public Health Service the research grant on which Dr. Lippman was operating, so that he ran out of funds to carry on his research, and decided to leave. He was offered a job as chief of medical service in an eastern hospital, accepted the job, and then was informed that because of representations from the Cedars of Lebanon Hospital the job would not be given to him,

  Now he has decided that it would be a good thing to move to Canada. The alternative is for him to practice medicine, and not carry on research - most of the foundations or agencies that provide money for support of research give it to a hospital or research institute, and Dr. Lippman is doubtful that he can get a job with circumstances as they are in the United States in a hospital or research institute.

  Could you give us some advice about the possibility of some sort of opening being found for Dr. Lippman in Canada? I may say that the way that Dr. Lippman has been living for several years has not involved his receiving a regular research salary. Most of the time he has made his living by practicing, devoting perhaps half of his time to his practice, which was mainly consulting work in the field of the kidney, and devoting the other half of his time to research on the kidney. For two or three years he received a stipend from the Columbia Foundation, and was able to devote three quarters of his time to research; then for two years he worked on a Fellowship from the John Simon Guggenheim Memorial Foundation, which was in part a stipend for his personal use, and in part a support of his researches; during this period he devoted most of his time to research. He has written me from New York that he would be willing to accept an appointment that carried only a small salary, and permitted him to devote most of his time to research. I think that he would be interested in an arrangement under which he could earn his living by practicing, provided that he also had facilities for carrying on his research.

  I think that Dr. Lippman is one of the leading research men in the field of kidney function in the world. You may have seen some of his papers - some of them have been published in the Proceedings of the National Academy of Sciences. He has continued Dr. Addis's work, and has introduced a number of new techniques of his own. In particular, he has developed a tissue-culture technique that permits him to test for the presence of nephrotoxic substances in the plasma of patients. He has also, in part in collaboration with Professor Dan H. Campbell of our laboratories, done some work on the effect of injecting into rats antibodies made by the injection of rat kidney tissue into rabbits; he has investigated the effect of these substances only a few minutes after the time of their injection into the rats, and has also been studying the nature of the reaction of the antibodies with kidney tissue. For several years I have been in close touch with Dr. Lippman in his research work, and I have formed a high opinion of his abilities as a research man.

  I may say that Dr. Lippman seems to me to be an extraordinarily fine man, with respect to character and personality. He has been interested in questions of medical freedom, and has had some trouble with the American Medical Association. He has opposed special loyalty oaths for doctors, has supported federal medical insurance, and in other ways has expressed opinions that run counter to those generally held by medical men in the United States - or, at any rate, officially held by the Medical Association. Dr. Lippman's trouble with the Cedars of Lebanon Hospital seems to be one of the results of the upset political situation in the country today.

  With best regards, I am

  Sincerely yours,

  Dear Parents,

  I was very happy to get your letters today, one from each, & one from Sid. Thank you very much for the Christmas present, I have not yet decided what to buy.

  I am looking forward to seeing you, is it very exciting, and I hope to accompany you on next summer’s trip. I can stay in Sweden with your friends for the rest of the summer.

  There is no hurry to order a car; if you want a Riley, order it from J.S. Inskip Inc. 304 E. 64 58. New York 2, or from International Motors. It should cost £1,055 delivered in London, without U.S. taxes or Atlantic transportation. At least my Nuffield price list gives that. MG is £530. I am not sure you can get another convertible. They are not listed. I am still in favour of a Jaguar sedan for the extra $300. The Riley engine was a hot egg in 1925 when it was designed, but the Jaguar engine is about the best in the world today for a reasonable price. For 10% extra cost you get 100% extra car. Oh hell.

  I am sorry not have sent you regularly the Times. I’ll work a routine.

  I shall write M. Olliver. Who was this old woman who was batty about indigo and brown sugar?

  I hope to get to Oxford soon. I want to see many people there.

  It snowed yesterday. Still slushy. But it is hoped that by March the weather will get better.

  Many thanks for everything.

  Much love,

  Peter

  Dr. Jerry Donohue

  Laboratory

  Cambridge England

  Dear Jerry:

  I am glad to have the list of interatomic distances. I have found out that Dr. Yakel has a complete list of interatomic distances for the 3.60-residue α helix. He has carried this out through five turns of the helix. I shall ask him to check your list item by item, to see whether he agrees with you. I know that the values that he has differ a little bit from the values used in our calculation, which, however, corresponded to a helix with 3.67 residues per turn, and perhaps the coordinates were a little bit different too. Yakel said that in general the disagreement was only 0.1 A.

  I shall look forward to seeing your manuscript on the helical structures.

  I enclose a copy of my Solvay Congress paper, without the figures, however - I don't think that the lack of the figures will bother you.

  As to the nucleic acid structure, I don't see any reason for it to be unsatisfactory as a structure for the nucleate ion, except of course that the negative charges are closer together than they would be if the phosphate groups were on the outside of the molecule, rather than near the axis. In any ease, hydrogen bonds are pretty weak, and a structure held together just by hydrogen bonds might not be satisfactory. The three chains in our structure are tucked together almost too tightly and bound by the sugar residues.

  I don't think that there is any use in trying to decide on substances tor you to investigate in connection with the work on nucleotides, until you get here next fall. I may say that I think, in view of your interest in settling permanently in California, that you should consider a job at U.S.C. seriously. My opinion of bids school has gone up, especially since the new chemistry laboratory has been constructed. The availability of government money for support of research makes the attractiveness of a job at U.S.C. greater than it was before the war. I don't think that there is any possibility of a permanent appointment here at the Institute, and it seems to me that if you are going to take a job at U.S.C. it would be better to take it now than a year later - you would have that much more seniority, for one thing.

  Dr. Donohue 2/10/53

  I hope that you will be back by 20 September 1953, in order to take part in the conference on the configuration of polypeptide chains in proteins.

  I have expressed again to the Guggenheim foundation my strong feeling that the amount of the stipend awarded in some cases, including your case, is too small. I think that the thing for you to do now is to write to the Guggenheim Foundation, sending them a breakdown of your expenses somewhat like the one that you have enclosed with your letter, pointing out that the cost of living and traveling has turned out to be greater than you had anticipated, and asking if an additional grant can be made to you. I do not know what will be done - I am not on the board this year.

  I shall be in Cambridge from Saturday to Tuesday, according to present plans, and I should have time for a good talk with you.

  With best regards, I am

  Sincerely yours,

  Linus Pauling:W

  ART/JS 10th February, 1953

  Professor Linus Pauling,

  Gates and Crellin Laboratories,

  California Institute of Technology,

  Pasadena 4,

  U.S.A.

  Dear Linus,

  On my return from India I found your letter of 19th December awaiting me with the exciting news that you think you have got the structure of the nucleic acids. I shall be most interested to get more detail of it and I hope you will keep me posted. Certainly if there is any help we can give you we will be only too glad to do so.

  I have seen Bragg and Cochran about this question of nucleotide examination because I agree with you that we are sorely in need of data on these substances. Cochran is actually doing an examination of adenylic acid b which he got from us, and he also has a sample of muscle adenylic acid which he is looking at in a preliminary way. I understand that these nucleotides are very difficult subjects for study and I do not think that Cochran is likely to tackle more than these two in the near future. I would say then that if you keep off the phosphates of adenosine you would not be duplicating their present work.

  As regards other people who might be doing something of the sort, Zussmann, who was here in the Cavendish and then went to Manchester, took away with him a sample of the crystalline barium salt of uridine-5' phosphate which we gave him. We have not heard from him since and so I do not know whether he is working on it seriously or not. Furberg in Oslo is also supposed to be working on cytidylic acid b and he was at us some time ago for a sample of ribose-5 phosphate, but again I know nothing about his progress.

  So far, of course, we have been the chief suppliers of these substances although a number of then can probably be got in the States. In addition to those above mentioned, the following ribonucleotides are crystalline and we either have them available or could get them for you:

  uridylic acid b and cytidine-5' phosphate,and cutidylic acid a

  Professor Linus Pauling page 2

  I have wondered, however, whether, since as far as I know no-one is doing anything about the deoxyribonucleotides, and since we have been synthesizing them and it is most unlikely that anyone else can produce them, you might wish to look at some of them. We have so far made both the 3' and 5' phosphates of thymidine and deoxycytidine, and we are at present preparing the corresponding substances from deoxyadenosine and deoxyguanosine. I wonder if you would let me know what things you think you would like to have, and as soon as I hear from you I can get samples of them sent off.

  You mention ATP in your letter. Actually we have never been able to crystallise free ATP, and the only crystalline derivative we have is acridine salt; the substance itself and its barium salt seem to be resolutely amorphous. At the moment I do not think we have any good preparation on hand but we have a main in the lab, who is making some ATP, so if you would like to have it I can let you have some in the form of a salt when it is ready.

  I look forward to hearing from you soon and meantime send best regards to all of you.

  Yours,

  Alex

  Brooklyn 2, New York

  Dear Dr. Oster:

  Thanks for your letter of 3 February.

  The point that you raise - that you do not feel that the equatorial spacings will be markedly altered whether one assumes seven parallel rods or six rods twisted around a central rod — is an interesting one. I would be inclined to agree with you, except for a contradictory fact. Crick has written that our expression is the first term in the complete expression for the seven-strand helical cable, which he has evaluated, and, since our expression differs from yours, the two approximate form factors do seem to be different.

  I am interested to learn about the work that you are carrying on.

  Sincerely yours,

  Linus Pauling:W

  18 February 1953

  Dear Peter:

  I am glad to have news from you about the nucleic acids. I have not understood why the Cambridge people should object to our structure as a structure for nucleate ion as well as nucleic acids. I think that I mentioned that the hydrogen atoms might be between the central oxygen atoms, in such a way as to form hydrogen bonds. The contact distance, 2.50 Å, is, however, a satisfactory one as van der Waals contact even when hydrogen atoms are not present – it is observed in many ionic crystals, such as the three forms of titanium dioxide, and also alumina. We did not try to place the sodium ions in sodium thymonucleate. They would, of course, be out some distance from the axis of the molecule. I am checking over the nucleic acid structure again, trying to refine the parameters a bit. I think that the original parameters are not exactly right. It is evident that the structure involves a tight squeeze for nearly all the atoms.

  I heard a rumor that Jim Watson and Crick had formulated this structure already sometime back, but had not done anything about it. Probably the rumor is exaggerated. We are glad to learn about what is going on at London. We had heard last summer that Miss Franklin was leaving, and then had heard that she was still there. Your letter tells us that she will be gone in a couple of months. I think that Miss Cowan, one of Dorothy Hodgkin’s girls, is supposed to go there. Miss Cowan attended my lectures in Oxford. She seems to me to be very good. I don’t think that I have ever met Miss Franklin. Also, I think that I have not met Wilkins, but Corey knows him, and has a very good opinion of him.

  Sid is coming. He ought to be there by this time – I think that he was to leave New York on the fourteenth. I hope that he gets the package to you that Mama sent to New York for him to bring. As to the car, I do not want to buy a Jaguar at the present time. First, I want to save some money, if possible. Also, I like having a sports model, although right at the moment I am not quite so enthusiastic. Mama and I spent two days out in the desert, at Calico Mountains, and we had the top down the whole time. I have been suffering somewhat from a sunburned face for three days now. I do not want a Riley salon, and I judge that you are right in saying that they aren’t making the drophead coupe. I do not want a Jaguar this summer. Would you look into the matter of a Sunbeam-Talbot? Here I want the drophead coupe or sports car, with room for at least three people (I think that it would not be courteous of us to get a car holding only two people). The Sunbeam-Talbot looks good to me. If you think that its price is satisfactory get it. I believe that it is described as $2800 delivered in Los Angeles.

  Could you do some scouting around in connection with our return to the United States? I have not had any luck with the travel agency here, in making reservations to return on a freighter, and to bring the car along with us. Mr. Bennett seems to very pessimistic in talking with Mrs. Wulf about this possibility. What Mama and I have in mind is that we would fool around in Europe, after the International Congress in Stockholm and Uppsala, which ends about the fifth of August, for several weeks in August, and then start home, about 20 August. We need to be in Pasadena by 15 September. We thought that if we could get on a freighter in Sweden, together with our car, we could then arrive in New York or some other American port – perhaps even New Orleans – by the end of August, and could drive home. We would want to have time enough for a pleasant trip across the continent – 8 or 9 days, say, from New York. If we could get from Europe to Los Angeles on a freighter, through the Panama Canal, without spending more than three weeks on the trip, we would be willing to consider that. I think that we could not stand as much as a month on a freighter – three weeks is enough. I would prefer landing somewhere on the east coast, or the Gulf, and driving on home. The time is flexible, provided that we get to Pasadena by 15 September. We should like, however, to stay in Europe as long as possible, preferably until the 20 August, or even a few days after that.

  We could embark anywhere in continental Europe – it is not necessary that we get on the freighter in Sweden, because we could drive back to Holland or Belgium, say, or France, and embark there. I think, however, that we would not want to travel on a freighter under registry other than one of the northern European countries. Would you check up at a travel agency, and let me know as soon as possible? Also let me know your recommendation about the Sunbeam-Talbot.

  I have received official word from the Unitarian Service Committee, inviting me to spend 25 days in Germany - 1 July to 25 July 1953. I am supposed to participate in two or three symposia, on the nature of muscle, and to visit departments of physiology in the German universities. The principal symposium is to be at Tübingen by the 8th of July, and probably we should arrive in Tübingen a bit before then.

  I enclose the check for 1 March. We have deposited $50 in your savings account here, the proceeds form cashing two $25 war bonds that have matured.

  Love from

  [Linus Pauling]

  Dear Alex:

  I am glad to have your letter of 10 February. I am sure that you had a good time in India - I shall wait until I get to Cambridge, in about six weeks to ask you about it.

  I am glad that Bragg and Cochran feel that it will be all right for us to attack the problem of the structure of some of the simple substances related to nucleic acids. Corey and I shall remember not to work on the phosphates of adenosine. Corey and I agree, however, that the best substances for us to attack are the deoxyribonucleotides, as you recommend. We should like very much to have samples of the 3' and 5' phosphates of thymidine and deoxycitidine, and then later, if you are successful with the corresponding substances from deoxyadenosine and deoxyguanosine we should like to have them. I think that we shall be able to put a post-doctorate man onto the study of these substances as soon as they arrive. We hope to have about three post-doctoral people working on these problems by fall. Each investigation is a big job, but I think that it will be worth while to carry out several of these structure determinations.

  I shall look forward to seeing you and Alison early in April.

  Sincerely yours,

  Structure of the Nucleic Acids

  WE have formulated a structure for the nucleic acids which is compatible with the main features of the X-ray diagram and with the general principles of molecular structure, and which accounts satisfactorily for some of the chemical properties of the substances. The structure involves three intertwined helical polynucleotide chains. Each chain, which is formed by phosphate di-ester groups and linking (β-D-ribofuranose or β -D-deoxyribofuranose residues with 3', 5' linkages, has approximately twenty-four nucleotide residues in seven turns of the helix. The helixes have the sense of a right-handed screw. The phosphate groups are closely packed about the axis of the molecule, with the pentose residues surrounding them, and the purine and pyrimidine groups projecting radially, their planes being approximately perpendicular to the molecular axis. The operation that converts one residue to the next residue in the polynucleotide chain is rotation by about 105° and translation by 3 ·4 A. A detailed description of the structure is appearing in the February 1953 issue of the Proceedings of the National Academy of Sciences of the United States of America.

  28 February 1953

  Dear Parents,

  Happy birthday, Daddy. I hope the next year is as successful as the last. Thank you the letters. We still feel that the structure requires sodium, and somewhere near the oxygens, whose negative charge must be cancelled to hold the molecule together. We agree that everything is a little tight. An unimportant point is that the pictures are of DNA and the structure of RNA. Actually, it is thought in the Cavendish that the structure is pretty good. We have nothing better to offer.

  Mamma, thank you very very much for my curtains and the surprise. My room takes on an entirely new aspect and ceases to be the dull, Cambridge hole it was. I had thought about divinity at Christmas and in January, but did not think it possible. It is grand. I ration myself, but liberally. I was very excited and glad to see Sid. We must have a party.

  Re automobiles: Convertible 4 seater Sunbeam-Talbot:2 ¹/₄ liter engine 70 b.h.p., 2865 lbs, w.b. 8ft 1 ", 895 in England. Well, I am almost in favor of a cheaper car; I prefer extremes. For instance, the Austin A-40 Sports 4-seater has 1.2 liter, 50bhp, 2068 lb, w.b. 7ft 8 " 586, $1640. The Hillman Minx convertible 4-seater (Linus has one) is 1 ¹/₄ liter 37.5 HP, 2016 lb, w.b. 7ft 9" 510, $1430. Notice that the Austin (a slight factory hop up) gets 50 bhp from 1.2 liters and the Sunbeam gets 70 from 2.26 liters. The Sunbeam Talbot looks pretty nice, and has a little more room than the Austin, but I don't think it is worth the extra $900. I think a Jaguar is worth the extra $1800 in space, comfort, and performance well maybe not. It would be better not to have a Jag in Europe. If you plan to leave the car here for more than one year, it should be bought and licensed, at least licensed, in France. One gets a "TT" International license plat there. It requires being in France once a year. I shall inquire among my friends here and at DNR London to see what the best thing to do is. Don't be in too much of a hurry.

  I went to the RI on Monday, and Riley and I had great fun. He took me to his club for supper. Very interesting. His wife is very nice. Presumable he has written you about USC. I told him all I knew about the place, not very much.

  Say, you might bring over a couple of etchings if it is convenient. I am beginning to hunt around for pictures, and have bought one, but need more. They can be framed here. You can bring a Navaho rug, too. I am toying with the idea of a Persian rug, but presumably they are a little expensive. British rugs are all flower and dull. "Don't show the dirt, my dear." Like everything else.

  Morgan builds an open four seater. It would be like the MG with four seats. No windows and no luggage space. 2.09 liters, 68 bhp, w.b 8ft, 1,736 lb. 580, $1620. More oomph than the Austin; and more sporty. I think I recommend the Austin A 40 Sports. Space is not great but about equal to the Sunbeam and Hillman.

  Sid Bernhard would appreciate it if you would send his manuscript.

  I shall probably go to London on April 1. and meet you there when you arrive. Might go to Oxford afterwards. Might go skiing in Austria, but doubt it.

  Would you please send $3.50 or $7.00 in the enclosed envelope? Makes me homesick. Many thanks.

  I like my Valentine very much. You are all darlings.

  Alfred Tissiers has a beautiful 1939 Bentl[e]y with a French closed 4 seater bod (sliding roof panel) which you can have. Plenty of space in it. Fast, powerful. Reasonably cheap, I expect. It is really too expensive to run her for him. It would be grand for me. I like closed coupes.

  Bragg may be next director of the R.I. He has been offered, but may not accept. If he does, the MRC unit presumably will mover there. What for me? This all unofficial and on the Q.T. Don't ask Bragg yet.

  How about thinking a little about insulin? No big guns brought to bear so far. M.W. 12000, much data.

  Much love,

  Peter
