before the celebrated emperor _Charles_ the fifth, declaring, that
heaven would one day call him to an account for those cruelties, which
he then had it in his power to prevent. The speech which he made on the

But his intreaties, by opposition of avarice, were rendered ineffectual:
and I do not find by any books which I have read upon the subject, that
