Hudibras. Part i. Canto ii. Line 633.

With many a stiff thwack, many a bang,

Hard crab-tree and old iron rang.

Hudibras. Part i. Canto ii. Line 831.

Like feather bed betwixt a wall

And heavy brunt of cannon ball.

Hudibras. Part i. Canto ii. Line 872.

Ay me! what perils do environ

The man that meddles with cold iron![211:5]
