Memoirs of Louis XIV and His Court and of the Regency — Volume 01

The Duchesse d'Orleans, commonly though incorrectly styled the Princess of Bavaria, was known to have maintained a very extensive correspondence with her relations and friends in different parts of Europe. Nearly eight hundred of her letters, written to the rincess Wilhelmina Charlotte of Wales and the Duke Antoine-Ulric of Brunswick, were found amongst the papers left by the Duchess Elizabeth of Brunswick at her death, in 1767. These appeared to be so curious that the Court of Brunswick ordered De Praun, a rivy Councillor, to make extracts of such parts as were most interesting. A copy of his extracts was sent to France, where it remained a long time without being published.
