the Comte de St. Germain, were talking about his secret for causing the
spots in diamonds to disappear. The King ordered a diamond of middling
size, which had a spot, to be brought. It was weighed; and the King said
to the Count, "It is valued at two hundred and forty louis; but it would
be worth four hundred if it had no spot. Will you try to put a hundred
and sixty louis into my pocket?" He examined it carefully, and said, "It
may be done; and I will bring it you again in a month." At the time

could make pearls grow, and give them the finest water. The King, paid
him great attention, and so did Madame de Pompadour. It was from her I
learnt what I have just related. M. Queanay said, talking of the pearls,
"They are produced by a disease in the oyster. It is possible to know
the cause of it; but, be that as it may, he is not the less a quack,
since he pretends to have the elixir vitae, and to have lived several
centuries. Our master is, however, infatuated by him, and sometimes
talks of him as if his descent were illustrious."

I have seen him frequently: he appeared to be about fifty; he was neither
fat nor thin; he had an acute, intelligent look, dressed very simply, but
in good taste; he wore very fine diamonds in his rings, watch, and
snuff-box. He came, one day, to visit Madame de Pompadour, at a time
