(Auto-generated)

Of government the properties to unfold, Would seem in me to affect speech and discourse; Since I am put to know that your own science Exceeds, in that, the lists of all advice My strength can give you: then no more remains But that to your sufficiency, as your worth is able, And let them work.†
Scene 1.1 *
I pr'ythee, Lucio, do me this kind service: This day my sister should the cloister enter, And there receive her approbation: Acquaint her with the danger of my state; Implore her, in my voice, that she make friends To the strict deputy; bid herself assay him; I have great hope in that: for in her youth There is a prone and speechless dialect Such as moves men; beside, she hath prosperous art When she will play with reason and discourse, And well she can persuade.†
Scene 1.3
