IV.ii.153 (104,7) [desperately mortal] This expression is obscure. Sir Thomas Hammer reads, mortally desperate. Mortally is in low conversation used in this sense, but I know not whether it was ever written. I am inclined to believe, that desperately mortal means desperately mischievous. Or desperately mortal may mean a man likely to die in a desperate state, without reflection or repentance. (see 1765, I,348,7)
IV.ii.187 (106,8) [and tie the beard] A beard tied would give a very new air to that face, which had never been seen but with the beard loose, long, and squalid. (1773)
IV.iii.4 (107,2) [First, here's young master Rash] This enumeration of the inhabitants of the prison affords a very striking view of the practices predominant in Shakespeare's age. Besides those whose follies are common to all times, we have four fighting men and a traveller. It is not unlikely that the originals of the pictures were then known.
IV.iii.17 (108,4) [master Forthlight] Should not Forthlight be Forthright, alluding to the line in which the thrust is made? (1773)
IV.iii.21 (108,6) [in for the Lord's sake] [i.e. to beg for the rest of their lives. Warburton.] I rather think this expression intended to ridicule the puritans, whose turbulence and indecency often brought them to prison, and who considered themselves as suffering for religion.
It is not unlikely that men imprisoned for other crimes, might represent themselves to casual enquirers, as suffering for puritanism, and that this might be the common cant of the prisons. In Donne's time, every prisoner was brought to jail by suretiship.
IV.iii.68 (110,7) [After him, fellows] Here was a line given to the Duke, which belongs to the Provost. The Provost, while the Duke is lamenting the obduracy of the prisoner, cries out,
After him, fellows, &c.
and, when they are gone out, turns again to the Duke.
IV.iii.72 (110,8) [to transport him] To remove him from one world to another. The French trepas affords a kindred sense.
