[Footnote 25: Page 220. The history of Madame de Monaco has been pleasingly told by Marquis Pierre de Ségur, in a study which forms the second part of the book entitled La Dernière des Condé. I have borrowed from this work many details regarding Betz which the Marquis de Ségur has extracted from the archives of Beauvais.] [Footnote 26: Page 243. Musées et Monuments de France, 1906, No. 10.] [Footnote 27: Page 244. The architect of the Temple of Friendship was called Le Roy; this is the name which is signed to the memorandum of the sums paid to the sculptor Dejoux for the casting of the group by Pigalle,--a memorandum which has been published by M. Rocheblave.] [Footnote 28: Page 249. Since these lines were written the Archaeological Committee of Senilis has published a work on the gardens of Betz by M. Gustav Macon. The gifted curator of the Musée Condé reproduces in this a very complete description of the gardens of the Princess of Monaco which must have been drawn up in the last half of 1792 or the first half of 1793. Its author is unknown. According to M. Macon, he was perhaps one of the writers who collaborated at that time in the preparation of Le Voyage 'pittoresque de la France' we might also think of Mérigot, who had just described the gardens of Chantilly so attractively. To this unpublished description M. Macon has added a series of notes in which he has collected all the information which he has found in the works of other historians or which he has himself discovered in regard to the artists who collaborated in the adornment of the domain of Betz. In short, he has exhausted the subject.] [Footnote 29: Page 266. The transformations of Chantilly have been studied and described by M. G. Macon Revue de l'art ancien et moderne, April, 1898.] [Footnote 30: Page 293. I have profitably consulted Livry et son abbaye, by Abbé A. E. Genty (1898).]
