"And the true blood that peeps fairly through it."
Collier's folio makes a natural and obvious correction, reading 'so fairly.' The usual reading is that of Steevens, a transposition of 'peeps' and 'fairly,' and I have retained it.
"Nothing she does or seems
But smacks of something greater than herself."
Here again the same folio makes the correction says for 'seems'; yet it is not very necessary.
"He tells her something
That makes her blood look on it."
This is probably the genuine text; but 'wakes her blood. Look on it!' the reading of Collier's folio, is very plausible. It is strange that neither Singer nor Dyce notice this reading. They read with Theobald 'look out.'
