ing convulsive efforts to express a
sentence of five words, which, after all, his gibberish made
unintelligible. His dress was as eccentric as his person was singular,
and his manners corresponded with both. He called himself Baron von
Bulow, and I saw him afterwards, in the autumn of 1797, at Paris, with
the same accoutrements and the same jargon, assuming an air of diplomatic
mystery, even while displaying before me, in a coffee-house, his letters
and instructions from his principal. As might be expected, he had the
adroitness to get himself shut up in the Temple, where, I have been told,
the generosity of your Sir Sidney Smith prevented him from starving.
No member of the foreign diplomatic corps here possesses either more
knowledge, or a longer experience, than the Prussian Ambassador, Marquis
of Lucchesini. He went with several other philosophers of Italy to
admire the late hero of modern philosophy at Berlin, Frederick the Great,
who received him well, caressed him often, but never trusted or employed
him. I suppose it was not at the mention of the Marquis's name for the
place of a governor of some province that this Monarch said, "My subjects
of that province have always been dutiful; a philosopher shall never rule
in my name but over people with whom I am discontented, or whom I intend

sectaries.
During the latter part of the life of this King, the Marquis of
Lucchesini was frequently of his literary and convivial parties; but he
was neither his friend nor his favourite, but his listener. It was first
under Frederick William II. that he began his diplomatic career, with an
appointment as Minister from Prussia to the late King of Poland. His
first act in this post was a treaty signed on the 29th of March, 1790,
with the King and Republic of Poland, which changed an elective monarchy
into an hereditary one; but, notwithstanding the Cabinet of Berlin had
guaranteed this alteration, and the constitution decreed in consequence,
in 1791, three years afterwards Russian and Prussian bayonets annihilated
both, and selfishness banished faith.
In July, 1790, he assisted as a Prussian plenipotentiary at the
conferences at Reichenback, together with the English and Dutch
Ambassadors, having for object a pacification between Austria and Turkey.
In December of the same year he went with the same Ministers to the
Congress at Sistova, where, in
