Count Charles de Mornay is a very remarkable young man. With a brilliant wit, the sallies of which can "set 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. Nothing can be more agreeable than the mode in which I pass my time here. I read from nine until twelve: order the household arrangements, and inspect the _menu_ at twelve: write letters or journalise from one until four; drive out till six or half-past; return home, dress, dine, pay visits, or receive them at home, and get to bed at one o'clock. How much preferable is the French system of evening visits, to the English custom of morning ones, which cut up time so abominably! Few who have lived much abroad could submit patiently to have their mornings broken in upon, when evening, which is the most suitable time for relaxation, can be enlivened by the visits that are irksome at other hours. Paris is now nearly as empty as London is in September; all the _élite_ of French fashionable society having taken their departure for their country houses, or for the different baths they frequent. I, who like not crowds, prefer Paris at this season to any other, and shall be rather sorry than glad when it fills again. Madame Craufurd, Lady Barbara and Colonel Craufurd, the Ducs de Gramont, Dalberg, and Mouchy, dined with us yesterday. We had music in the evening, The Duc Dalberg is agreeable and well-bred, and his manner has that suavity, mingled with reserve, said to be peculiar to those who have lived much at courts, and filled diplomatic situations. The Duc was Minister Plenipotentiary from Baden at Paris, when Napoleon was First Consul, and escaped not censure on the occasion of the seizure of the unfortunate Duc d'Enghien; of the intention of which it was thought he ought to have apprised his court, and so have prevented an event which has entailed just blame on all concerned in it, as well as on some who were innocent. There is nothing in the character of the Duc Dalberg to warrant a belief of his being capable of lending himself to aught that was disloyal, for he is an excellent man in all the relations of life, and is esteemed and respected by as large a circle of friends as most persons who have filled high situations can boast of. The Duc de Mouchy is a very amiable as well as high-bred man; he has been in England, and speaks English with fluency.
