"In the fourth issue, "Quelques réflexions sur L'Abbé Constantin", signed "Compère Loriot", a remarkable critique of the stage adaptation of Ludovic Halévy's novel (1882), staged at the Théâtre du Gymnase on November 4, 1887, must also be attributed to Proust. It is a mature and subtle text, since its author is severe about the adaptation of the novel by the father of his fellow contributor to Le Lundi, and takes the opportunity to praise the new edition of L'Abbé Constantin illustrated by Madeleine Lemaire and published by Calmann-Lévy (the thirty-four watercolours are exhibited at the Goupil gallery, rue Chaptal)."
