CD annotations

End of letter: ‘Valparaiso | Sent &c &c 1834’ ink


The date is established by the relationship between this memorandum and the letter to Caroline Darwin, 13 October 1834 (Correspondence vol. 1; see n. 3 below). A summary of this letter was published in Correspondence vol. 1 under the name Frederick W. Eck and the date [September 1834].
CD refers to Eck’s measurements in his geological notes (DAR 35: 376, 410–12). The places on Eck’s list lie along the routes of CD’s expeditions from Valparaiso to Santiago between 14 and 27 August 1834, and from San Fernando back to Valparaiso between 19 and 25 September 1834 (‘Beagle’ diary, pp. 250–7, 262–3).
CD climbed Bell mountain on 16 August 1834. In his letter to Caroline Darwin, 13 October 1834, he gave its height as 4700 feet, matching Eck’s figure, but corrected that to 6400 in a later publication (letter to Caroline Darwin, 13 October 1834 and n. 1; see also ‘Beagle’ diary, p. 252).
CD stayed in Casablanca on 25 and 26 September 1834 (‘Beagle’ diary, p. 263).
