“Some of these are given in the following communications.”

Alongside the Watson-Crick paper in the April 25, 1953, issue of Nature were separately published papers by scientists Maurice Wilkins and Rosalind Franklin of King’s College, who worked independently of each other. The Wilkins and Franklin papers described the X-ray crystallography evidence that helped Watson and Crick devise their structure. The authors of the three papers, their lab chiefs, and the editors of Nature agreed that all three would be published in the same issue.

The “following communications” that our authors are referring to are the papers by Franklin and Wilkins, published on the journal pages immediately after Watson and Crick’s paper. They (and other papers) can be downloaded as PDF files ( Adobe Acrobat required) from Nature’s 50 Years of DNA Web site.
