15. Van Gogh is probably referring here to the mediation of
Gauguin’s friend
Schuffenecker in the possible purchase of Gauguin’s painting
Negresses talking by the banker’s wife Mrs Pouzin, to whom Schuffenecker gave painting lessons. See
Correspondance Gauguin, pp. 488-489 (nn. 260, 262). Gauguin had told Theo that he was counting on this sale to enable him to go to Arles (
see letter 635, n. 3). In the end, though, Mrs Pouzin did not buy the painting, which Theo had on consignment. Cf.
letter 627, n. 6.
