Comment on a related paper by D'Haultfoeuille and Fevrier

But he is worst, who (beggarly) doth chaw
Others’ wits’ fruits, and in his ravenous maw
Rankly digested, doth those things out spew,
As his own things; and they are his own, ‘tis true,
For if one eat my meat, though it be known
The meat was mine, th’ excrement is his own.
