Though I must necessarily fall into repetitions by treating the same subject so often, I cannot help recommending to you again the utmost attention to your air and address. Apply yourself now to Marcel’s lectures, as diligently as you did formerly to Professor Mascow’s; desire him to teach you every genteel attitude that the human body can be put into; let him make you go in and out of his room frequently, and present yourself to him, as if he were by turns different persons; such as a minister, a lady, a superior, an equal, and inferior, etc. Learn to seat genteelly in different companies; to loll genteelly, and with good manners, in those companies where you are authorized to be free, and to sit up respectfully where the same freedom is not allowable. Learn even to compose your countenance occasionally to the respectful, the cheerful, and the insinuating. Take particular care that the motions of your hands and arms be easy and graceful; for the genteelness of a man consists more in them than in anything else, especially in his dancing. Desire some women to tell you of any little awkwardness that they observe in your carriage; they are the best judges of those things; and if they are satisfied, the men will be so too. Think now only of the decorations. Are you acquainted with Madame Geoffrain, who has a great deal of wit; and who, I am informed, receives only the very best company in her house? Do you know Madame du Pin, who, I remember, had beauty, and I hear has wit and reading? I could wish you to converse only with those who, either from their rank, their merit, or their beauty, require constant attention; for a young man can never improve in company where he thinks he may neglect himself. A new bow must be constantly kept bent; when it grows older, and has taken the right turn, it may now and then be relaxed.
I have this moment paid your draft of L89 75s.; it was signed in a very good hand; which proves that a good hand may be written without the assistance of magic. Nothing provokes me much more, than to hear people indolently say that they cannot do, what is in everybody’s power to do, if it be but in their will. Adieu.
