The writer praises the recipient, an aide-maréchal and a noted poet, for their grace and skill in their literary craft, particularly highlighting their work Rosière. He expresses disappointment with a critic of the poem who reproaches a minor element of the story, arguing that such a criticism is misplaced given the character’s virtue. The writer thanks the recipient for a delightful package, which brought him happiness, and notes their continued admiration for Mr Dorat, though acknowledging that the response to Ninon and the odes was not from him.
