is this alone that can give all your other talents their full lustre and
value; and, consequently, it is this which should now be thy principal
object of your attention. Observe minutely, wherever you go, the allowed
and established models of good-breeding, and form yourself upon them.
Whatever pleases you most in others, will infallibly please others in
you. I have often repeated this to you; now is your time of putting it in
practice.

Pray make my compliments to Mr. Harte, and tell him I have received his
letter from Vienna of the 16th N. S., but that I shall not trouble him
with an answer to it till I have received the other letter which he
promises me, upon the subject of one of my last. I long to hear from him
after your settlement at Turin: the months that you are to pass there
will be very decisive ones for you. The exercises of the Academy, and the
manners of courts must be attended to and acquired; and, at the same
time, your other studies continued. I am sure you will not pass, nor
desire, one single idle hour there: for I do not foresee that you can, in
any part of your life, put out six months to greater interest, than those
next six at Turin.

We will talk hereafter about your stay at Rome and in other parts of
Italy. This only I will now recommend to you; which is, to extract the
spirit of every place you go to. In those places which are only
distinguished by classical fame, and valuable remains of antiquity, have
your classics in your hand and in your head; compare the ancient
geography and descriptions with the modern, and never fail to take notes.
Rome will furnish you with business enough of that sort; but then it
furnishes you with many other objects well deserving your attention, such
as deep ecclesiastical craft and policy. Adieu.
