This must needs be practice:

and again,

Let me have way to find this practice out.

V.i.145 (125,6) [nor a temporary medler] It is hard to know what is meant by a temporary medler. In its usual sense, as opposed to perpetual, it cannot be used here. It may stand for temporal: the sense will then be, I know him for a holy man, one that meddles not with secular affairs. It may mean temporising: I know him to be a holy man, one who would not_ temporise, or take the opportunity of your absence to defame you. Or we may read,

Not scurvy, nor a tamperer and medler:

not one who would bare tampered with this woman to make her a false evidence against your deputy.

V.i.160 (126,8) [So vulgarly and personally accus'd] Meaning either so grosly, with such indecency of invective, or by so mean and inadequate witnesses.

V.i.205 (128,2) [This is a strange abuse] Abuse stands in this place for deception, or puzzle. So in Macbeth,

This strange and self abuse,

means, this strange deception of himself.
