On his return he was nominated prefect of the Seine "département". His concessions to the Parisian mob and his extreme gentleness towards those who demanded the prosecution of the ministers of Charles X led to an unflattering comparison with Jérôme Pétion under similar circumstances. Louis Philippe's government was far from satisfying his desires for reform, and he persistently urged the "broadening of the bases of the monarchy," while he protested his loyalty to the dynasty. He was returned to the chamber of deputies for the department of Eure in 1831. The day after the demonstration of June 1832 on the occasion of the funeral of General Lamarque, he made himself indirectly the mouthpiece of the Democrats in an interview with Louis Philippe, which is given at length in his "Mêmoires". Subsequently, in pleading before the court of cassation on behalf of one of the rioters, he secured the annulling of the judgments given by the council of war.
