Comes from as far a source: ought it to end

This way, by leakage through their scaffold-planks

Into Rome's sink where her red refuse runs?

Sirs, I beseech you by blood-sympathy,

If there be any vile experiment

In the air,—if this your visit simply prove,

When all 's done, just a well-intentioned trick,

That tries for truth truer than truth itself,

By startling up a man, ere break of day,

To tell him he must die at sunset,—pshaw!
