Because the learn’d are in the dark

How opium, mercury, acts, and bark,

To such reply you’ll make no answers,

For much I question if you can, sirs;

But rather for retort uncivil,

The poker take and lay them level.[92]

From Haygarth, borrowing a rare hint,

Tell how these tractors, ’tis apparent,

The most insidious thing in nature,

Will e’en bewitch the operator![93]
