A legal broom's a moral chimney-sweeper,

And that's the reason he himself's so dirty;

The endless soot[532] bestows a tint far deeper

Than can be hid by altering his shirt; he

Retains the sable stains of the dark creeper,

At least some twenty-nine do out of thirty,

In all their habits;—not so you, I own;

As Cæsar wore his robe you wear your gown.[533]
