  "I always had an idea that it would be bungled; but was willing to hope, and am still so. Whatever I can do by money, means, or person, I will venture freely for their freedom; and have so repeated to them (some of the Chiefs here) half an hour ago."
• (intransitive) To act or work incompetently; to fumble.
  "Physis is nothing else but the vegetable World, the Universall comprehension of Spermaticall life dispersed throughout. […] For Physis (as I said) is not the divine Understanding it self, but is as if you should conceive, an Artificers imagination separate from the Artificer, and left alone to work by it self without animadversion. Hence Physis or Nature is sometimes puzzeld and bungells in ill disposed matter, because its power is not absolute and omnipotent."
