The effects of Brainsick's letters

Your lines were all so sweet, and work't so wel,
So purg'd me too, that I can hardly tel
Whether they wrought on my affections more
Or on my body, I drew thence such store
Of precious Elixer, and so much
Compounded Cates, whose qualitie was such,
That where my Physick promis'd me but seven,
By virtue of your lines I had eleven.
But yet I'l tel you; troth 'twas een forgot
It purg'd and scar'd and wipt off you know what;
It griev'd mee your fair hand should undergo
So foul an office as to wipe it too;
But rather then your hand or paper bee
Stain'd with this act, let the guilt lie on mee.
I did it 'cause I know that you could write
Such lines again as fast as I could—
Write to me oftner pray! so I may save
Physicians fees, and may bum-fodder have.
