For 'And' Mr. Collier found End in MS. in a copy of the folio.
"Than you have or will deserve at my hand."
So the 2nd folio reads; the 1st has 'to deserve'; and perhaps a noun may have been omitted after 'have.'
"I think not so.—Why, do you not know him?"
Some would transfer 'not' to the former speech, but I think it more likely that not was omitted.
Ber. "Where are my other men?—
Hel. Monsieur, farewell."
The folio gives all this to Helena; while Theobald, followed by the Cambridge editors, reads "Ber. Where are my other men, monsieur? Farewell."
