full I know, thou know'st no part, I knowing all my peril, thou no art. What I can do can do no hurt to try, Since you set up your rest 'gainst remedy. He that of greatest works is finisher Oft does them by the weakest minister: So holy writ in babes hath judgment shown, When judges have been babes; great floods have flown From simple sources, and great seas have dried When miracles have by the greatest been denied. Oft expectation fails and most oft there Where most it promises, and oft it hits Where hope is coldest and despair most fits. I must not hear thee; fare thee well, kind maid; Thy pains not used must by thyself be paid: Proffers not took reap thanks for their reward. Inspired merit so by breath is barr'd: It is not so with Him that all things knows As 'tis with us that square our guess by shows; But most it is presumption in us when The help of heaven we count the act of men. Dear sir, to my endeavours give consent; Of heaven, not me, make an experiment. I am not an impostor that proclaim Myself against the level of mine aim; But know I think and think I know most sure My art is not past power nor you past cure.

Methinks in thee some blessed spirit doth speak His powerful sound within an organ weak: And what impossibility would slay In common sense, sense saves another way. Thy life is dear; for all that life can rate Worth name of life in thee hath estimate, Youth, beauty, wisdom, courage, all That happiness and prime can happy call: Thou this to hazard needs must intimate Skill infinite or monstrous desperate. Sweet practiser, thy physic I will try, That ministers thine own death if I die. If I break time, or flinch in property Of what I spoke, unpitied let me die, And well deserved: not helping, death's my fee; But, if I help, what do you promise me? Make thy demand. But will you make it
