The file comprises the following items (as b/w photocopies):
1. A satirical note, in the style of an in memoriam card, sent to Maurice Wilkins and signed by Franklin and Gosling, with the following text (holograph, Franklin's hand): "It is with great regret that we have to announce the death, on Friday 18th July 1952[,] of DNA helix (crystalline). Death followed a protracted illness which an intensive course of Besselised injections had failed to relieve. A memorial service will be held next Monday or Tuesday. It is hoped that Dr M H F Wilkins will speak in memory of the late helix." The text refers to the 'A' form (low humidity) of DNA. The card is reproduced in Brenda Maddox, Rosalind Franklin: The Dark Lady of DNA (2002), p. 185.
2. Rosalind E Franklin and R G Gosling, "Rough Draft / A note on molecular configuration in sodium thymonucleate" (dated 17 March, 1953). A draft of the paper that appeared in Nature alongside the first Watson and Crick paper (25 April, 1953).
Note: the draft paper by Franklin and Gosling is also in the file in the form of five photographic facsimiles of the five photocopies.
