The address is that of ‘Robarts, Lubbock & Co. Bankers’ in the city of London (Post Office London directory 1861). Lubbock travelled into London daily from his home in Chislehurst, Kent (Hutchinson 1914, 1: 52).

CD was unable because of illness to read the paper Lubbock sent him (see letter to John Lubbock, 23 January [1862]). It was probably a manuscript version of Lubbock’s paper entitled ‘On the geologico-archæological discoveries in Denmark, Switzerland, and France’ (Lubbock 1862a), which he read before the Geological and Polytechnic Society of the West Riding of Yorkshire on 19 February 1862. The first part of this paper (pp. 238–56) was a condensed version of Lubbock’s observations on ancient lake dwellings in Switzerland, which were shortly to be published in the Natural History Review (Lubbock 1862b). In the latter part of the paper (Lubbock 1862a, pp. 256–73), which was later expanded for publication in the Natural History Review (Lubbock 1862c; see also letter from John Lubbock, 15 May 1862), he described the human artefacts discovered by Jacques Boucher de Perthes in the river gravels of the Somme valley, and discussed their relevance in establishing the antiquity of the human species. The last three pages of the published paper contained Lubbock’s most radical public statement on human antiquity to date, concluding that the ‘cave men’ of the Somme were not definitively ‘the earliest human settlers in Western Europe’. He continued (p. 273): We have not indeed as yet the materials to decide the question, but if we were to express any opinion on the subject, it would seem more philosophical to imagine that the genus Homo dates back to a period as ancient as the other widely-spread genera of mammalia

John and Ellen Frances Lubbock lived about five miles from Down, in Chislehurst, Kent. See also letter from E. F. Lubbock to Emma Darwin, [January 1862], n. 4.
