#intrāre, sī possim, castra hostium volō#, L. 2, 12, 5, _I propose to
enter the camp of the enemy, if I be able_. #tē neque dēbent adiuvāre,
sī possint, neque possunt, sī velint#, _V._ 4, 20, _they ought not to

nātūra repente mittat, quid respondēmus?# Lucr. 3, 931, _if Nature of a

must be settled by definitions_ (2074).
