clearest thoughts. The Poet examines that most which he produceth with the greatest leisure, and which, he knows, must pass the severest test of the audience, because they are aptest to have it ever in their memory: as the stomach makes the best concoction when it strictly embraces the nourishment, and takes account of every little particle as it passes through.
