To Raphael Meldola   27 January [1872]1

Pray keep the specimens as long as you wish.— I have read your letter with interest & pleasure.—2 I have vague recollection of Mr Trimen in Transact. Linn. Soc. or of Mr Butler of Brit. Mus. mentioning the case of ♂ alone mimicking some other Butterfly.3

Down. Jan. 27th

The year is established by the relationship between this letter and the letter from Raphael Meldola, 25 January 1872.
CD refers to Roland Trimen, the Transactions of the Linnean Society of London, Arthur Gardiner Butler, and the British Museum. CD was probably recalling a letter by Butler in Nature, 29 December 1870, p. 165 (see also Correspondence vol. 19, letter from A. G. Butler, 2 June 1871 and nn. 5–8, 13).
