Sc. 2.
"Did she see thee the while, old boy?"
The 3rd folio first added thee.
"Challenge me the Count's youth to fight with him."
I think 'him' should be thee. Ritson read you.
Sc. 3.
"And thanks, and ever thanks. Good turns oft."
Here we have an instance of the advantage of transposition, for the folio has "oft good turns." 'Turns' is a dissyllable. Theobald read 'thanks, and oft.'
