Footnotes

The date range is established by CD’s residence in Down from September 1842 onwards (Correspondence vol. 2, Appendix II). William Baxter and his son William Walmisley Baxter of Bromley, Kent, were CD’s regular chemists.
The recipe (one drachm of verdigris, one drachm of sal ammoniac, half a drachm of lamp-black, ten drachms of water) is for ink suitable for writing on zinc plant labels (W. Herbert 1837, p. 411). There is an annotated copy of W. Herbert 1837 in the Darwin Library–CUL (see Marginalia 1: 372–6); a note inside the back cover reads, ‘411 Labels for Gardens’.
