To J. J. Weir   30 April [1872]1

Down, Beckenham, Kent

April 30

My dear Sir

Many thanks for your note. I am not much surprised at incipient disease causing an alteration in the female, so that she would cease to be attractive to the male.2 I am sorry that your official duties have been of late so heavy; but I suppose it is the fate of all whose services become more valuable.3 I much hope, however, that your duties may not altogether interrupt your wonderful powers of observation in Natural History.

My dear Sir | yours sincerely | Ch. Darwin.

The text of the letter is taken from a copy made for Francis Darwin for his editions of CD’s letters (LL, ML), although Francis did not publish it. The year was supplied by the copyist.
The letter from Weir has not been found. In Descent 1: 262–3, CD discussed the preferences among animals for more vigorous and attractive members of the opposite sex, noting that it was usually females who exercised this choice.
Weir was employed in HM Customs, rising to the rank of accountant and controller-general in 1874 (ML 1: 319).
