Paris, 1958. Single leaf (21.2 x 21.1 cm). Typed letter with handwritten signature.

Typed letter (dated 15 October 1958), by the French geologist, palaeontologist and malacologist Éliane Basse de Ménorval (1899-1985) to the French marine biologist, ichthyologist, parasitologist, and director of the Service des Pêches Coloniales, Robert Philippe F. Dollfus (1887-1976). Dollfus was a son of the malacologist Gustave Frédérique Dollfus (co-author of the famous Les mollusques marins du Rousillon), and was interested in Mollusca himself. Paul Henri Fischer wrote his obituary, in the Journal de Conchyliologie 114(3-4), p. 131. In this letter, Basse de Ménorval asks Dollfus for a work written by Gustave Frédérique Dollfus, which she needs for her survey of the Meuse region in order to prepare a new geological map of the Verdun region. Basse de Ménorval went to Madagascar for the Muséum d'Histoire naturelle in Paris (1930-1932) and made geological and palaeontological observations on which she based several important papers. Back in Paris, she collaborated on the geological maps of Luxembourg and France. Later she became directeur scientifique de recherches au Centre national de la recherche scientifique. Trimmed in the lower margin, probably by the author. A few annotations by Dollfus, including a note that Basse was a specialist in ammonites, and that a reply was sent on the 24th of October 1958. A very good, clean item.
