Signed letter written in January 1728 addressed to Madame de Glappion Religieuse St Cyr, nun of the House of St Louis.
I am very grateful for the new assurances you have given me of our friendship, Madam, and I make an infinite case of it, and it cannot be otherwise. Loving you as I am, your letter is so full of compliments that I am almost angry, it is as if I were reading it, that you are still trying to win my friendship, remember that I have given it all to your merit, and that I dispense you from so many civilities, being inevitably, Madam, your best friend.
Superb perfectly preserved red wax seal with the Arms.
