You had very good teeth, and I hope they are so still; but even those who
have bad ones, should keep them clean; for a dirty mouth is, in my mind,
ill manners. In short, neglect nothing that can possibly please. A
thousand nameless little things, which nobody can describe, but which
everybody feels, conspire to form that WHOLE of pleasing; as the several
pieces of a Mosaic work though, separately, of little beauty or value,
when properly joined, form those beautiful figures which please
everybody. A look, a gesture, an attitude, a tone of voice, all bear
their parts in the great work of pleasing. The art of pleasing is more
particularly necessary in your intended profession than perhaps in any
other; it is, in truth, the first half of your business; for if you do
not please the court you are sent to, you will be of very little use to
the court you are sent from. Please the eyes and the ears, they will
introduce you to the heart; and nine times in ten, the heart governs the
understanding.

Make your court particularly, and show distinguished attentions to such
men and women as are best at court, highest in the fashion, and in the
opinion of the public; speak advantageously of them behind their backs,
in companies whom you have reason to believe will tell them again.
Express your admiration of the many great men that the House of Savoy has
produced; observe that nature, instead of being exhausted by those
efforts, seems to have redoubled them, in the person of the present King,
and the Duke of Savoy; wonder, at this rate, where it will end, and
conclude that it must end in the government of all Europe. Say this,
likewise, where it will probably be repeated; but say it unaffectedly,
and, the last especially, with a kind of 'enjouement'. These little arts
are very allowable, and must be made use of in the course of the world;
they are pleasing to one party, useful to the other, and injurious to
nobody.
