Dear WW: is this the sonnet you had in mind?

My mistress' eyes are nothing like the sun;
Coral is far more red than her lips' red:
If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.
I have seen roses damask'd, red and white,
But no such roses see I in her cheeks;
And in some perfumes is there more delight
Than in the breath that from my mistress reeks.
I love to hear her speak,--yet well I know
That music hath a far more pleasing sound;
I grant I never saw a goddess go,
My mistress when she walks, treads on the ground;
And yet, by heaven, I think my love as rare
As any she belied with false compare.
