Sc. 2.
"An end, sir, to your business. Give Helen this."
For 'An end' I feel almost certain we should read Attend, or possibly And now. I have, however, made no change in the text of my Edition. Some point 'An end, sir: to your business.'
Sc. 3.
"Mort de vinaigre! is not that Helena?"
"And writ as little beard."
For 'writ' we should, I think, read wore or with. Mr. Dyce, however, says it was "the phraseology of Shakespeare's time." He should, then, have given us examples of it; for write man and such like are not such. Perhaps this and the following speeches of Lafeu should be Asides.
