ANDRADA E SYLVA, BONIFACIO JOZÉ DE, a distinguished Brazilian naturalist and statesman, was born in 1765 and died in 1838. He took a prominent part in the Revolution of Brazil, and in 1831 was recalled from his banishment in France to accept the charge of the young emperor's education, but after two years, political hostility again drove him into retirement. His works consist chiefly of memoirs relative to mines.
