A good wench; give it me.
EMILIA. What will you do with't, that you have been so earnest
To have me filch it?
IAGO. [Snatching it. ] Why, what is that to you?
EMILIA. If't be not for some purpose of import,
Give't me again. Poor lady, she'll run mad
When she shall lack it.
IAGO. Be not acknown on't; I have use for it.
Go, leave me. Exit Emilia.
I will in Cassio's lodging lose this napkin,
And let him find it. Trifles light as air
Are to the jealous confirmations strong
As proofs of holy writ; this may do something.
The Moor already changes with my poison:
Dangerous conceits are in their natures poisons,
Which at the first are scarce found to distaste,
But with a little act upon the blood
Burn like the mines of sulphur. I did say so.
Look, where he comes!

Re-enter Othello.

Not poppy, nor mandragora,
Nor all the drowsy syrups of the world,
Shall ever medicine thee to that sweet sleep
Which thou owedst yesterday.
OTHELLO. Ha, ha, false to me?
IAGO. Why, how now, general! No more of that.
OTHELLO. Avaunt! be gone! Thou hast set me on the rack.
I swear 'tis better to be much abused
Than but to know't a little.
IAGO.
