My dear Darwin

Many thanks for the enclosed, which I have copied, & return.1

I can give you another instance in which that curious habit (in the Butler family) of raising the arm when asleep & letting the wrist fall over the nose, has occurred. You may recollect the case I sent you, which you quoted.2 The new instance is this:—

The 7th child of one of the other sons, had this peculiarity also. It was first observed and commented on by the nurse & pointed out by he⁠⟨⁠r⁠⟩⁠ to the mother, the nurse being wholly ignorant of the peculiarity hav⁠⟨⁠ing⁠⟩⁠ existed in other members of the family, & the mother who had heard of its existence had never until that time, paid attention to the account. (The son in question is Spencer Butler; the peculiarity as far as known, runs thus:—3

The crosses are those that are known to have it.)

Their grandfather,2 out of 8 children
and3 out of 17 grandchildren (about)
are known to have it

Ever sincerely Yr. | Francis Galton

In 1871, Galton had sent CD an account of the arm-raising habit of his brother-in-law Henry Montagu Butler, Butler’s father, George Butler, and his daughter Agnes Isabel (see Correspondence vol. 19, letters from Francis Galton, 22 December 1871 and [after 22 December 1871]). CD cited the case in Expression, pp. 33–4 n. 8.
Spencer Perceval Butler was a son of George Butler. His wife was Mary Butler, and their seventh child was Arthur Francis Butler.
