(Pasted inside the back cover is a statement of Eddington’s account with the Clarendon Press in respect of sales of Stars and Atoms during the year ending 31 Mar. 1944.)

(See the general note on this file.)

(This paper includes a description of Eddington’s visit to the Laboratory in Oct. 1934. W. E. Burcham described the circumstances of its composition as follows: ‘towards the end of 1934 Sir Arthur Eddington wrote a pamphlet describing the Cavendish and its achievements to form the basis of ‘an appeal to the friends of science and of Cambridge’. The pamphlet was published in Feb. 1935, and privately circulated to possible benefactors both within and outside Cambridge. See ‘The Cavendish High-voltage Laboratory 1935-39’, Notes and Records of the Royal Society of London, vol. liii, pp. 121-2. (The title appears under the heading ‘Miscellaneous’ in D2/3.))

(The words ‘Broadcast—Calcutta’ have been added above the title and struck through. Cf. Douglas, pp. 105-6. Two lectures of the same title are listed in D2/3.)

(Folios 13–15, which are wanting, may have been discarded intentionally; see the note on f. 12.)

(Marked by Slater: ‘Lectures as delivered orally.’ The date assigned to this document is the date the lectures were given.)

(This is an early version of part of a report to the Royal Society by the Joint Permanent Eclipse Committee. The latest date mentioned in it is 14 July 1919, and the report was received by the Society on 30 October and read on 6 November.)
