In the letter, Voltaire notes that as soon as Émilie du Châtelet has finished her great business, he will have no more pressing matters than to take advantage of the kindnesses of the Prince and Princess. He ends by asking them to accept his deepest respects. The letter is dated 15 August 1749.

The poem preceding the letter was written by Voltaire whilst in Lorraine, likely between February and December 1748. In it, he praises Lunéville and the pleasures he experienced there amongst the wise. The final lines of the poem have been heavily corrected. Besterman suggests that they may have been transcribed from the autograph original (CMV34556) which is similarly revised.

Voltaire has signed the verse.

Count von Manteuffel sent this copy of the poem to Count von Brühl from Berlin on 21 October 1740.

The poem which originally featured at the start of the letter is missing from this copy.
