Mon cher et illustre Confrère,

J’ai pris aussitôt après la réception de votre lettre des renseignements sur M. Legrain, qui était pour moi un inconnu. Vous trouverez dans le Bulletin de l’Acad. R. de Médecine de Belgique (1867, IIIe. série, Tome I No. 1) la discussion du travail de ce Monsieur.— Il a été démontré par le Dr. Crocq, qui lui mérite toute Confiance, qu’il était matériellement impossible que M. Legrain ait fait les expériences qu’il annonce.—2 Tout cela est un indigne mystification qui a eu pour auteur un homme dont la moralité est caractérisée dans la même publication du Dr. Crocq.— Ce M. Legrain n’a jamais joui, du reste d’aucune considération; c’est un hableur, un blagueur, qui a pu en imposer un moment à quelques médecins peu sérieux, mais dont il n’a plus été question depuis sa fameuse équipée faite à propos de ses prétendus expériences sur les mariages consanguins.—

Veuillez recevoir, mon cher et illustre Confrère, l’expression de mes sentiments les plus respectueux et les plus dévoués. | Edouard Van Beneden.

CD’s letter to Beneden has not been found. In a paper presented to the Académie royale de médecine de Belgique (Legrain 1866), Jean Baptiste Legrain claimed to have interbred several generations of closely related rabbits without ill effects. The veracity of his account was challenged by Jean Crocq (Bulletin de l’Académie royale de médecine de Belgique 3d ser. 1 (1867): 26–49). Without referring to Beneden by name, CD used his information in the second edition of Variation in a note added to a discussion of the effects of inbreeding in rabbits (Variation 2d ed. 2: 100 n. 20). CD also recalled the episode in his autobiography (‘Recollections’, p. 425). See also letter to G. H. Darwin, [19 August 1875].

My dear and renowned colleague,

Upon receiving your letter I straightaway made enquiries concerning Mr Legrain, who was unknown to me. You will find a discussion of the work of that gentleman in the Bulletin of the Royal Academy of Medicine of Belgium (1867, IIIrd series, Vol. I No 1).— It has been demonstrated by Dr Crocq, who for his part merits every confidence, that it was materially impossible for Mr Legrain to have carried out the experiments he announces.—2 All this is an unworthy hoax authored by a man whose morality is characterised in the same publication by Dr Crocq.— This Mr Legrain, besides, has never enjoyed any consideration; he is a braggart and a humbug, who managed to deceive certain irresponsible physicians for a while, but there has been no question of that since his famous lark concerning supposed experiments on consanguineous marriages.—

I remain, my dear and illustrious colleague, yours very truly. | Edouard Van Beneden.
