Bears stamped initials: E.D. The stamp is the studio sale stamp of Eugène Delacroix, 1864 (F. Lugt, Repertoire des ventes, no. 838a)
On Delacroix's anatomical drawings see M. Sérullaz, Dessins d'Eugène Delacroix, 2 vols., Paris 1984, vol. 1, pp. 352-361, nos. 938-977. Most of them were contained in two lots in his studio sale of 1864: lot 659 (71 sheets) and lot 660 (55 sheets). Most of them are untraced today (1997). A group of forty of them was acquired by Moreau-Nélaton, put into an album and presented to the Musée du Louvre: these are the drawings catalogued by Sérullaz, op. cit. Three others are reproduced in Eugène Delacroix (1798-1863), paintings, drawings and prints from North American collections, Metropolitan Museum of Art, New York, 1991, pp. 123-125, nos. 54-56, as in the possession of Karen B. Cohen. One is in the Ashmolean Museum, Oxford (Report of the visitors, 1965, p. 45). All of these drawings bear numbers in the same hand (Sérullaz's "main étrangère") as the number written on the Wellcome drawing
