If we separate the discoveries made during the last five or six years from the jumble of quarrels, disputes, cavilling, quackery, and law-suits (for there have been all those), they consist in this- - In 1846 M. Mace found in the (then) Royal Library, amongst the "Collection Du Puys," a letter of Montaigne, addressed to the king, Henri IV., September 2, 1590. In 1847 M. Payen printed a letter, or a fragment of a letter of Montaigne of February 16, 1588, a letter corrupt and incomplete, coming from the collection of the Comtesse Boni de Castellane. But, most important of all, in 1848, M. Horace de Viel-Castel found in London, at the British Museum, a remarkable letter of Montaigne, May 22, 1585, when Mayor of Bordeaux, addressed to M. de Matignon, the king's lieutenant in the town. The great interest of the letter is that it shows Montaigne for the first time in the full discharge of his office with all the energy and vigilance of which he was capable. The pretended idler was at need much more active than he was ready to own. M. Detcheverry, keeper of the records to the mayoralty of Bordeaux, found and published (1850) a letter of Montaigne, while mayor, to the Jurats, or aldermen of the town, July 30, 1585. M. Achille Jubinal found among the manuscripts of the National Library, and published (1850), a long, remarkable letter from Montaigne to the king, Henri IV., January 18, 1590, which happily coincides with that already found by M. Mace. Lastly, to omit nothing and do justice to all, in a "Visit to Montaigne's Chateau in Perigord," of which the account appeared in 1850, M. Bertrand de Saint-Germain described the place and pointed out the various Greek and Latin inscriptions that may still be read in Montaigne's tower in the third-storey chamber (the ground floor counting as the first), which the philosopher made his library and study.
