could do them no harm. 'Ne quid nimis', is a most excellent rule in
everything; but commonly the least observed, by people of your age, in
anything.

As to your future motions, I am very well pleased with them, and greatly
prefer your intended stay at Verona to Venice, whose almost stagnating
waters must, at this time of the year, corrupt the air. Verona has a pure
and clear air, and, as I am informed, a great deal of good company.
Marquis Maffei, alone, would be worth going there for. You may, I think,
very well leave Verona about the middle of September, when the great
heats will be quite over, and then make the best of your way to Naples;
where, I own, I want to have you by way of precaution (I hope it is
rather over caution) in case of the last remains of a pulmonic disorder.
The amphitheatre at Verona is worth your attention; as are also many
buildings there and at Vicenza, of the famous Andrea Palladio, whose
taste and style of buildings were truly antique. It would not be amiss,
if you employed three or four days in learning the five orders of
architecture, with their general proportions; and you may know all that
you need know of them in that time. Palladio's own book of architecture
is the best you can make use of for that purpose, skipping over the
mechanical part of it, such as the materials, the cement, etc.

Mr. Harte tells me, that your acquaintance with the classics is renewed;
the suspension of which has been so short, that I dare say it has
produced no coldness. I hope and believe, you are now so much master of
them, that two hours every day, uninterruptedly, for a year or two more,
will make you perfectly so; and I think you cannot now allot them a
greater share than that of your time, considering the many other things
you have to learn and to do. You must know how to speak and write Italian
perfectly; you must learn some logic, some geometry, and some astronomy;
