will weigh less. I wager that diamond powder has not sufficient force to
kill a man.

Side by side with these fanciful excursions into science, come more
serious ones, as in the note on Algebra, which traces its progress since
the year 1494, before which 'it had only arrived at the solution of
problems of the second degree, inclusive.' A scrap of paper tells us that
Casanova 'did not like regular towns.' 'I like,' he says, 'Venice, Rome,
Florence, Milan, Constantinople, Genoa.' Then he becomes abstract and
inquisitive again, and writes two pages, full of curious, out-of-the-way
learning, on the name of Paradise:

The name of Paradise is a name in Genesis which indicates a place of
pleasure (lieu voluptueux): this term is Persian. This place of pleasure
was made by God before he had created man.

It may be remembered that Casanova quarrelled with Voltaire, because
Voltaire had told him frankly that his translation of L'Ecossaise was a
bad translation. It is piquant to read another note written in this style
of righteous indignation:

Voltaire, the hardy Voltaire, whose pen is without bit or bridle;
