arising out of the stomacke, then they worke not so clearely and distinctly as they doe when the humors are setled.
That the phantasie of it selfe worketh no alteration within a man,
it is proved thus.
First, nihil agit extra genus suum, as thornes bring not forth figges,
[Reason, 1] nor thistles grapes, Mat. 7.16.

Thirdly, it worketh not eminenter by way of excellencie upon the bodies, for then it should produce such an effect which should be more excellent than the cause.
The spirits then ascending from the heart,
