Re-enter Cassio.[6279]

As he shall smile, Othello shall go mad;[6280]
And his unbookish jealousy must construe[6281] 100
Poor Cassio's smiles, gestures and light behaviour,[6282]
Quite in the wrong. How do you now, lieutenant?[6283]

Cas. The worser that you give me the addition[6284]
Whose want even kills me.

Iago. Ply Desdemona well, and you are sure on 't. 105
Now, if this suit lay in Bianca's power,[6285]
How quickly should you speed!

Cas. Alas, poor caitiff![6286]

Oth. Look, how he laughs already![6287]

Iago. I never knew a woman love man so.[6288]

Cas. Alas, poor rogue! I think, i' faith, she loves me.[6289] 110

Oth. Now he denies it faintly and laughs it out.[6287][6290]

Iago. Do you hear, Cassio?
