It must not be omitted, that one of the elder quartos reads, thou dost stone thy heart; which I suspect to be genuine. The meaning then will be, thou forcest me to dismiss thee from the world in the state of the murdered without preparation for death, when I intended that thy punishment should have been a sacrifice atoning for thy crime.
I am glad that I have ended my revisal of this dreadful scene. It is not to be endured.
V.ii.134 (505,3) false as water] As water that will support no weight, nor keep any impression.
V.ii.151 (506,4) villainy has made mocks with love] Villainy has taken advantage to play upon the weakness of a violent passion.
V.ii.162 (506,5) Thou hast not half that power to do me harm, /As I have to be hurt] [Hamner: to bear hurt] The Oxford Editor saw well the meaning of his author, but weakened his expression. She means to say, I have in this cause power to endure more than thou hast power to inflict.
V.ii.183 (507, 6) charm your tongue] I know not whether I have read, or whether my own thoughts hare suggested, an alteration of this passage. It seems to me not improbable, that Shakespeare wrote clam your tongue; to clam a bell, is to cover the clapper with felt, which drowns the blow, and hinders the sound.
V.ii.211 (509,7) she with Cassio had the act of shame/A thousand times committed] This is another passage which seems to suppose a longer space comprised in the action of this play than the scenes include.
V.ii.253 (512,2) It was a sword of Spain, the ice-brook's temper] [In the first edition it is, Isebroke's temper. Thence corrupted to Ice-brook's.—Ebro's temper; the waters of that river of Spain are particularly famous for tempering of steel. POPE.] I believe the old reading changed to ice-brook is right. Steel is hardened by being put red hot into very cold water.
V.ii.286 (513,3)
I look down towards his feet; but that's a fable.
