Those protective and delicate coatings of wax,
Which are meant to resist the corrosive attacks
That would ruin the copper completely;
Thin cerements which whoso remembers the Bee
So applauded by Watts, the divine LL.D.,
Will be careful to spread very neatly.
For why? like some intricate deed of the law,
Should the ground in the process be left with a flaw,
Aqua-fortis is far from a joker;
And attacking the part that no coating protects,
