and Mr. Harte, at Berlin. I should be glad that yours were more minute
with regard to your motions and transactions; and I desire that, for the
future, they may contain accounts of what and who you see and hear, in
your several places of residence; for I interest myself as much in the
company you keep, and the pleasures you take, as in the studies you
pursue; and therefore, equally desire to be informed of them all. Another
thing I desire, which is, that you will acknowledge my letters by their
dates, that I may know which you do, and which you do not receive.

As you found your brain considerably affected by the cold, you were very
prudent not to turn it to poetry in that situation; and not less
judicious in declining the borrowed aid of a stove, whose fumigation,
instead of inspiration, would at best have produced what Mr. Pope calls a
souterkin of wit. I will show your letter to Duval, by way of
justification for not answering his challenge; and I think he must allow
the validity of it; for a frozen brain is as unfit to answer a challenge
in poetry, as a blunt sword is for a single combat.

You may if you please, and therefore I flatter myself that you will,
profit considerably by your stay at Berlin, in the article of manners and
useful knowledge. Attention to what you will see and hear there, together
with proper inquiries, and a little care and method in taking notes of
what is more material, will procure you much useful knowledge. Many young
people are so light, so dissipated, and so incurious, that they can
hardly be said to see what they see, or hear what they hear: that is,
they hear in so superficial and inattentive a manner, that they might as
well not see nor hear at all. For instance, if they see a public
building, as a college, an hospital, an arsenal, etc., they content
themselves with the first 'coup d'oeil', and neither take the time nor
the trouble of informing themselves of the material parts of them; which
