Lady Blessington erinnert sich an Charles de Mornay:

»Count Charles de Mornay was presented to me today. Having heard of him only as –

“The glass of fashion and the mould of form,
The observed of all observers,”

I was agreeably surprised to find him one of the most witty, well-informed, and agreeable young men I have ever seen. Gay without levity, well-read without pedantry, and good-looking without vanity. Of how few young men of fashion could this be said! But I am persuaded that Count Charles de Mornay is made to be something better than a mere man of fashion.«

»Charles de Mornay is a very remarkable young man. With a brilliant wit, the sallies of which can “get the table in a roar;” it is never used at the expense of others, and, when he chooses to be grave, the quickness and justice of his perception, and the fine tact and good sense which mark his reflections, betray a mind of no common order, and give the promise of future distinction.«

»Count Charles de Mornay dined here yesterday, en famille. How clever and amusing he is! Even in his liveliest sallies there is the evidence of a mind that can reflect deeply, as well as clothe its thoughts in the happiest language. To be witty, yet thouroughly good-natured as he is, never exercising his wit at the expense of others, indicates no less kindness of heart than talent.
I know few things more agreeable than to hear him and his cousin open the armoury of their wit, which, like summer lightning, flashes rapidly and brightly, but never wounds.«
