'A noise within. Let her come in.
Enter Ophelia.
Laer. How now? what noise is that?'
Rowe followed the Folios, Pope the Quartos, reading 'Let ... that?' as one line. Theobald first transferred the stage direction, Enter Ophelia, to follow the first line of Laertes's speech.
Note XXVII.
IV. 5. 163. Capell was the first to print these words as not forming part of the song. In the Folios they are printed like the former lines in italics. As there is no change of type in the Quartos, it is impossible to say on which side their authority is. There is a comma after 'teare' (or 'tear') in all the Quartos and Folios, except the sixth Quarto, which has a full stop.
Note XXVIII.
IV. 5. 166. Ophelia's speech, or song, is printed as three lines in the Quarto, thus:
'Oph. You must sing a downe a downe,
And you call him a downe a. O how the wheele becomes it,
It is the false Steward that stole his Maisters daughter.'
