consult the treaties Neustadt and Abo,
with regard to the disputes, which you read of every day in the public
papers, between Russia and Sweden. For the affairs of Italy, which are
reported to be the objects of present negotiations, recur to the
quadruple alliance of the year 1718, and follow them down through their
several variations to the treaty of Aix-la-Chapelle, 1748; in which (by
the bye) you will find the very different tenures by which the Infant Don
Philip, your namesake, holds Parma and Placentia. Consult, also, the
Emperor Charles the Sixth's Act of Cession of the kingdoms of Naples and
Sicily, being a point which, upon the death of the present King of Spain,
is likely to occasion some disputes; do not lose the thread of these
matters; which is carried on with great ease, but if once broken, is
resumed with difficulty.

Pray tell Mr. Harte, that I have sent his packet to Baron Firmian by
Count Einsiedlen, who is gone from hence this day for Germany, and passes
through Vienna in his way to Italy; where he is in hopes of crossing upon
you somewhere or other. Adieu, my friend.

LETTER CIX

LONDON, March 29, O. S. 1750

MY DEAR FRIEND: You are now, I suppose, at Naples, in a new scene of
'Virtu', examining all the curiosities of Herculaneum, watching the
eruptions of Mount Vesuvius, and surveying the magnificent churches and
public buildings, by which Naples is distinguished.

You have a court there into the bargain, which, I hope, you frequent and
attend to. Polite manners, a versatility of mind, a complaisance even to
enemies, and the 'volto sciolto', with the 'pensieri stretti', are only
to be learned at courts, and must be well learned by whoever would either
shine or thrive in them. Though they do not change the nature, they
smooth and soften the manners of mankind. Vigilance, dexterity, and
flexibility supply the place of natural force; and it is the ablest mind,
not the strongest body that prevails there. Monsieur and Madame Fogliani
will, I am sure, show you all the politeness of courts; for I know no
better bred people than they are. Domesticate yourself there while you
stay at Naples, and lay aside the English coldness and formality. You
have also a letter to Comte Mahony, whose house I hope you frequent, as
it is the resort of the best company. His sister, Madame Bulkeley, is now
here; and had I known of your going so soon to Naples, I would have got
you, 'ex abundanti', a letter from her
