Iniurious Duke, that threatest where's no cause

Buck. True Madame, none at all: what call you this?
Away with them, let them be clapt vp close,
And kept asunder: you Madame shall with vs.
Stafford take her to thee.
Wee'le see your Trinkets here all forth-comming.
All away.
Enter.

Yorke. Lord Buckingham, me thinks you watcht her well:
A pretty Plot, well chosen to build vpon.
Now pray my Lord, let's see the Deuils Writ.
What haue we here?

Reades.

The Duke yet liues, that Henry shall depose:
But him out-liue, and dye a violent death.
Why this is iust, Aio aeacida Romanos vincere posso.
Well, to the rest:
Tell me what fate awaits the Duke of Suffolke?
By Water shall he dye, and take his end.
What shall betide the Duke of Somerset?
Let him shunne Castles,
Safer shall he be vpon the sandie Plaines,
Then where Castles mounted stand.
Come, come, my Lords,
These Oracles are hardly attain'd,
And hardly vnderstood.
