Should interfuse him to the finger-ends" --
X. The Pope, 1564.

"You have the sunrise now, joins truth to truth."
X. The Pope, 1763.

"One makes fools look foolisher fifty-fold
By putting in their place the wise like you,
To take the full force of an argument
Would buffet their stolidity in vain."
XI. Guido, 858.

Here the infinitive "To take" might be understood, at first look,
as the subject of "Would buffet"; but it depends on "putting", etc.,
and the subject relative "that" is suppressed: "an argument [that]
would buffet their stolidity in vain."

"Will you hear truth can do no harm nor good?"
XI. Guido, 1915.

"I who, with outlet for escape to heaven,
Would tarry if such flight allowed my foe
To raise his head, relieved of that firm foot
Had pinned him to the fiery pavement else!"
XI. Guido, 2099.

i.e., "that firm foot [that] had (would have) pinned."
