EXAMPLE
“… Although I am not ignorant that there be some which make two kindes of these Serpents, because of the two names rehearsed in the title, yet when they haue laboured to describe them seuerally, they can bring nothing or very little wherein their story doth not agree, so as to make twaine of them, or to handle them asunder, were but to take occasion to tautologize , or to speake one thing twice. …”
