Sc. 4.
"Is like a good thing, being often read,
Grown sear'd and tedious."
The folio has 'fear'd'; the correction is Warburton's. It is a most unusual use of 'sear'd' in the sense of dry; sear would seem less strange. So Heath also thought.
"To thy false seeming.—Blood thou art blood still!—
Let us write 'Good Angel' on the Devil's horn,
'Tis not the Devil's crest.... How now! Who's there?"
Pope read 'but blood'; Malone 'still blood.'
