Down Bromley Kent

June 18th

My dear Fox

I have been looking over old letters of yours, & I want to ask a question: but I do so on condition, that you just answer it, at your leisure as briefly as possible.— Dixon says that his Musk Ducks often took to roost & perch on high places or ridge of Barn, or perch along side Hens &c.—1 I see you used to keep Musk ducks—did you ever observe this or any tendency to lay eggs on high places? Case bears on retention of aboriginal habits— I see in your letter capital case of a cross between white & some other var. of Musk-duck reverting to black & white or aboriginal colour of Musk Duck.—2

Can you give me any authoritive case with exact dates of period of gestation of any breeds of Dog?3 How I wish I knew for instance about Blood Hounds— I suppose no chance of Galton’s knowing; indeed I do not know whether Mr H. Galton is alive.—4

Poor Etty has now been in bed for exactly 7 weeks with low fever; but at last, thank God, she is beginning to gain little strength.—5

Yours affect. | C. Darwin

Footnotes

Dixon 1848, p. 66. The passage is marked in CD’s copy (Darwin Library–CUL).
Fox’s letter discussing this point has not been found. CD cited Fox’s responses in Variation 2: 40: ‘the Rev. W. D. Fox tells me that, by putting a white drake to a slate-coloured duck, black birds, pied with white, like the wild musk-duck, were always produced.’
In Variation 1: 30, CD stated: ‘Rev. W. D. Fox has given me three carefully recorded cases of [the period of gestation of] retrievers’.
CD refers to John Howard Galton, a relative of both Fox and CD, with whom Fox had corresponded about bloodhounds in 1838. See Correspondence vol. 2, letter from W. D. Fox, [c. November 1838].

Summary

Has WDF ever observed musk ducks laying eggs in high places? The case bears on retention of aboriginal habits.

Also wants data on period of gestation of dog breeds. [See Variation 1: 30.]
