I.i.108-125 (152,3) These, and all other lines confin’d within crotchets throughout this play, are omitted in the folio edition of 1623.  The omissions leave the play sometimes better and sometimes worse, and seen made only for the sake of abbreviation.

I.i.153 (154,2)

  Whether in sea or fire, in earth or air,
  The extravagant and erring spirit hies
  To his confine]

According to the pneumatology of that tine, every element was inhabited by its peculiar order of spirits, who had dispositions different, according to their various places of abode.  The meaning therefore is, that all spirits extravagant, wandering out of their element, whether aerial spirits visiting earth, or earthly spirits ranging the air, return to their station, to their proper limits in which they are confined.  We might read,

“—­And at his warning “Th’ extravagant and erring spirit hies “To his confine, whether in sea or air, “Or earth, or fire.  And of, &c.

But this change, tho’ it would smooth the construction, is not necessary, and being unnecessary, should not be made against authority.

  The head is not more native to the heart,
  The hand more instrumental to the mouth,

[W:  The blood ...  Than to the throne] Part of this emendation I have received, but cannot discern why the head is not as much native to the heart, as the blood, that is, natural and congenial to it, born with it, and co-operating with it.  The relation is likewise by this reading better preserved, the counsellor being to the king as the head to the heart.
