Under the article 'Brinvilliers,' we find as follows:--

Bastille; and, while there, he learned the art of compounding subtle
and most mortal poisons; and, when he was released, he taught it to
the lady, who exercised it with such success, that, in one year, her

the utmost tenderness for her victims, and nursed them assiduously. On
her father she is said to have made eight attempts before she
succeeded. She was very religious, and devoted to works of charity;
and visited the hospitals a great deal, where it is said she tried her
poisons on the sick.'

ancient and foulest modern assassins, and Lord Byron's mistress was
