Sec. 74. He will also convince the Scholar, that the Artifice of a
Professor is never more pleasing, than when he deceives the Audience
with agreeable Surprizes; for which reason he will advise him to have
Recourse to a seeming Plainness, as if he aim'd at nothing else.

Sec. 75. But when the Audience is in no farther Expectation, and (as I may

profound _Judgment_.

Sec. 5. That they are produced by a singular and beautiful _Invention_,

Sec. 6. That, being govern'd by the rigorous, but necessary, Precepts of
