hem only as exercitations for the mind, and turn always to
settle with common sense.

I stumbled, the other day, at a bookseller's, upon "Comte Gabalis," in
two very little volumes, which I had formerly read. I read it over again,
and with fresh astonishment. Most of the extravagances are taken from the
Jewish Rabbins, who broached those wild notions, and delivered them in
the unintelligible jargon which the Caballists and Rosicrucians deal in
to this day. Their number is, I believe, much lessened, but there are
still some; and I myself have known two; who studied and firmly believed
in that mystical nonsense. What extravagancy is not man capable of
entertaining, when once his shackled reason is led in triumph by fancy
and prejudice! The ancient alchemists give very much into this stuff, by
which they thought they should discover the philosopher's stone; and some
of the most celebrated empirics employed it in the pursuit of the
universal medicine. Paracelsus, a bold empiric and wild Caballist,
asserted that he had discovered it, and called it his 'Alkahest'. Why or
wherefore, God knows; only that those madmen call nothing by an
intelligible name. You may easily get this book from The Hague: read it,
for it will both divert and astonish you, and at the same time teach you
'nil admirari'; a very necessary lesson.

Your letters, except when upon a given subject, are exceedingly laconic,
and neither answer my desires nor the purpose of letters; which should be
familiar conversations, between absent friends. As I desire to live with
you upon the footing of an intimate friend, and not of a parent, I could
wish that your letters gave me more particular accounts of yourself, and
of your lesser transactions. When you write to me, suppose yourself
conversing freely with me by the fireside. In that case, you would
naturally mention the incidents of the day; as where you had been, who
you had seen, what you thought of them, etc. Do this in your letters:
acquaint me sometimes with your studies, sometimes with your diversions;
tell me of any new persons and characters that you meet with in company,
and add your own observations upon them: in short, let me see more of you
in your letters. How do you go on with Lord Pulteney, and how does he go
on at Leipsig? Has he learning, has he parts, has he application? Is he
good or ill-natured? In short, What is he? at least, what do you think
him? You may tell me without reserve, for I promise
