LAMARTINE Alphonse de. Sur la Politique rationnelle. Paris, Gosselin, 1831; in-8, 132-[2] pp, Second Empire binding, half magenta morocco, gilt fillet, smooth spine decorated with gilt fillets, gilt title throughout, speckled edges. First edition. Bound at the head: 2 autograph letters from Lamartine to the lawyer and senator Gustave Louis Chaix d'Est-Ange "My dear colleague, I have received and seen with the keenest interest your young protégée. Mme de Lamartine also wants to look after her and will see her on Monday. I have little doubt that her ideas are very sincere, but I think that there is far more danger (...) for her mother's memory and expense than benefit in pursuing such an impossible quest. I will advise her to do so and I believe that you should do so for her happiness and honour". Chaix d'Est-Ange defended Lamartine's interests when the publisher Béthune, who had acquired the rights to the Histoire des Girondins in 1844, proved unable to meet his commitments and broke off the contract the following year. From the library of Bourg de Bozas Chaix d'Est-Ange, with the bookplate of the Château de Prye.
