- f1 4488.f1Baxter ran a chemist's shop and `stamp office' in High Street, Bromley, Kent (Post Office directory of the six home counties 1862), and regularly supplied medicines to the Darwins (see, for example, Correspondence vol. 10, letter to W. W. Baxter, 26 January ). Another possible recipient is the Shrewsbury chemist Blunt and Salter (see letter from E. A. Darwin, [after 31 March 1864?] and n. 3).
- f2 4488.f2The date is conjectured from the relationship between this letter and the letter from E. A. Darwin 7 May ; it seems probable that Emma Darwin would have consulted Jenner about the effects of podophyllin following Erasmus Alvey Darwin's information that it might be unwise for CD to take such a strong purgative. Jenner prescribed podophyllin following his first visit to CD on 20 March 1864 (see letter from E. A. Darwin to Emma Darwin, 30 [March 1864?] and n. 4). See also n. 3, below.
- f3 4488.f3According to Emma Darwin's diary (DAR 242), CD started taking podophyllin and colchicum on 24 March 1864. For information on the course of treatment prescribed by Jenner, see letter to J. D. Hooker, 13 April  and n. 6. Sodae carbonas exsiccata, or dried sodium carbonate, was an alkaline salt often prescribed as a treatment for acid dyspepsia (Royle and Headland 1865, pp. 97 and 100). Taraxacum was a preparation made from the fresh roots of the common dandelion, Taraxacum officinale, was used as a mild tonic, laxative, and diuretic (Beasley 1865, pp. 501--3, and Royle and Headland 1865, pp. 502--3).
- f4 4488.f4The letter from Emma Darwin to Jenner has not been found.
- f5 4488.f5Jenner had advised CD to limit his intake of fluids (see letter to J. D. Hooker, 13 April  and n. 6).
