From W. B. Tegetmeier   [after 25 April 1871]1

Descent vol 1

Dixon. foot note 270 is very unreliable authority—almost certainly wrong in this instance—2

Descent of Man

Erratum— Vol 2. page 242. line 14 for “Walruses” read “Narwhals”3

CD annotations

1.1 Descent … instance— 2.2] crossed pencil
The date is established by the relationship between this letter and the letter to W. B. Tegetmeier, 25 April [1871]
In Descent 1: 270 n. 9, CD referred to Edmund Saul Dixon’s comment in Ornamental and domestic poultry (E. S. Dixon 1848) that the eggs of the guinea fowl are infertile when more than one female is kept with the male. The reference was removed in Descent 2d ed., p. 220. This first part of the letter is on a separate scrap of paper pasted to the second part.
CD corrected this passage in the third printing of Descent. He had also been informed of the error by Hermanus Hartogh Heijs van Zouteveen (see letter from Hermanus Hartogh Heijs van Zouteveen, 7 April 1871 and n. 6).
