From Raphael Meldola   4 June 1879

21 John Street, | Bedford Row, W.C.

June 4/79

My dear Mr. Darwin,

I read to the Entom. Soc. this evening a translation of Fritz Müller’s admirable paper from Kosmos &, as might have been expected, it was severely criticised by many of our members the majority of whom are as you know nothing more than species describers. In fact I do not think anyone fairly grasped the line of argument through inability to follow the simple algebraical reasoning which F.M. has adopted to express the state of affairs with regard to the action of Natural Selection on 2 allied species both possessing distasteful qualities.1 However the paper will appear in full in our Proceedings & my object in writing to you is to ask you if you could kindly assist me in getting the loan of the wood-blocks from the publishers of Kosmos— it would save us the expense of having them recut & this is a matter for consideration in the present state of our funds.2

I must beg your kind forgiveness for thus troubling you. If you let me know to whom I can apply it will be sufficient.

Yours very truly, | R. Meldola.

Footnotes

Fritz Müller’s paper ‘Ituna und Thyridia. Ein merkwürdiges Beispiel von Mimicry bei Schmetterlingen’ (‘Ituna and Thyridia; a remarkable example of mimicry in butterflies) had appeared in Kosmos, May 1879 (F. Müller 1879c). Müller had shown the similarity in the wing patterns of Ituna ilione (a synonym of Lycorea ilione) and Thyridia megisto (a synonym of Methona megisto). Müller reasoned that two distasteful species that shared similar colour patterns would both benefit since any predator, having tasted one, would reject both species in future. Müller further noted that the gain to either species, in mathematical terms, would be the ratio of the two populations squared (ibid., p. 108).
In a note to the English version of Müller’s paper, Meldola thanked Ernst Krause, the editor of Kosmos, for providing electrotypes of the woodcuts (F. Müller 1879d, p. xx n.).
