BOSOLA. Doth he study physiognomy?
There 's no more credit to be given to the face
Than to a sick man's urine, which some call
The physician's whore, because she cozens<15> him.
He did suspect me wrongfully.

FERDINAND. For that
You must give great men leave to take their times.
Distrust doth cause us seldom be deceiv'd.
You see the oft shaking of the cedar-tree
Fastens it more at root.

BOSOLA. Yet take heed;
For to suspect a friend unworthily
Instructs him the next way to suspect you,
And prompts him to deceive you.

FERDINAND. There 's gold.

BOSOLA. So:
What follows? [Aside.] Never rain'd such showers as these
Without thunderbolts i' the tail of them.--Whose throat must I cut?

FERDINAND. Your inclination to shed blood rides post
Before my occasion to use you. I give you that
To live i' the court here, and observe the duchess;
To note all the particulars of her haviour,
What suitors do solicit her for marriage,
And whom she best affects. She 's a young widow:
I would not have her marry again.
