The note accompanying these papers (B4/8) begins as follows: ‘This card folder contains a small number of loose and partly unidentified sheets that were separated from the otherwise orderly arrangement of the Eddington papers that had been in the hands of Professor N. B. Slater.’ There follows a brief description of the three letters (B4/5–7) and the sheets in Eddington’s hand (B4/1–9). Eddington’s manuscripts have been listed as nine items. The first (B4/1) forms a sequence of four sheets numbered from 36 to 39, formerly stapled together, as Dewhirst’s note records. The first sheet was marked by Slater in red biro: ‘(Attached to MS §a).’, apparently referring to B3/1, which comprises thirty-five sheets, though the character represented by the section-mark is indistinct. The next three items also appear to form distinct sequences, possibly all from the same doc-ument: B4/2, comprising six sheets numbered from 3 to 8; B4/3, two sheets, of which the second, unnumbered, clearly follows the first, which is numbered 10; and B4/4, comprising two sheets numbered 12 and 13. The remaining five sheets have been listed singly (B4/5–9). The first two of these contain similar tables on the back. The folder, which was simply marked with a ringed ‘A’, has been discarded.

These manuscripts are all in Eddington’s own hand, with the exception of the ringed pencil number on the first page of each and the foliation (in red biro, except B2/20), which were added by Slater, the former in June 1945, the latter about the end of 1947. Other notes by Slater indicate that there is a sheet missing from B2/22 between ff. 4 and 5, and that B2/29 f. 14 is a modification of f. 4.
