• AHP journal entry in journal entitled "France and England 1952 also Toronto" RE: "Mons. Paris thinks it would be a good idea to increase the discussion on fundamental particles: especially their discovery and properties. It said that the French edition of Gen. Chem. wouldn't sell very well even if brought out in paper covers because the French students don't have any money to buy any books. Prof. Paris is carrying on work on the rotation of complexes in crystals: especially the NH4 + ion. He asked when a new edition of the Nature of the Chemical Bond would appear and said there was a great need for a 2nd edition." "Paris. Bernal wrote to be sure we'd come to Birkbeck to talk to Carlyle about the structure of ribonuclease in relation to our protein structures" "Paris. Feather rachis Keratin. Jim Watson suggested that feather rachis keratin might have a completely different structure than that suggested by P and C. he said that the succession of layer lines is that expected for a helix with identity distance 94.6 A. or twice this, and that the infra red data indicate [alpha] helices approximately at right angles to the axis instead of parallel to the axis. He suggested that the repeating unit might be a short segment of [alpha] helix with these units themselves in a helical arrangement. The data in Table I of PandC indicate that the large helix is about 38 A in diameter, and the data in Table II suggest that there might be 31 units in perhaps 4 turns. Examination of the layer lines with use of the equation of [Cochasen?], Crick, and Vand might settle this matter."

  16 August 1952

  Dear Parents,

  Willie Crellin and I are on our way home after a wonderful visit in Hawaii. We are very sorry to leave, but I am supposed to get some work done this summer. No ink on this tub.

  I presume you told Kendrew I had decided not to get married. I had neglected to inform him. Fine, I expect to have a grand time. I guess I have to work too.

  I shall give a short list of my financial obligations:

  Due Aug 17 to Cunard White Star $110

  Estimate of train and baggage fair 150

  Owed Alex Rich for eastern trip 12

  " H.P. Robertson " " " 20

  Stock of colour film for Europe ~36

  I would like to spend for records $100

  GE pickup, diamond needle and tone arm $46

  Food for 30 days (Aug 16→ Sept 16)

  for Crellin and me._________________________45

  I shan't total it. Scared.

  Linda knows where the $62 dollars went. I paid $13.25 for my watch, $5.00 for some photographs, $1.20 for color film and a little more.

  Additional: owed to Linus and Anita $12 I am sorry, but I and Crellin only have $6.32 and I owe money. Maybe Cunard will cancel my reservation when I don't pay. You must come to Hawii sometime again in the next two years. It is grand.

  [Crellin begins writing here]

  It is a shame to leave Oahu. We brought pineapple, etc, but they wouldn't let us bring them home, We had a wonderful time. You would love the place. Thousands of Hibiscus, etc. Pete and I drove around the Island yesterday. Picked pineapple sugar. Saw sugar being harvested.

  Love,

  Crellin

  I hope I see you before I go.

  Much love,

  Peter
