  The Second Part of the Novum Organum deals with Bacon's rule for interpreting nature, even if he provides no complete or universal theory. He contributes to the new philosophy by introducing his tables of discovery (Inst. Magna, IV), by presenting an example of particulars (Inst. Magna, II), and by observations on history (Inst. Magna, III). It is well known that he worked hard in the last five years of his life to make progress on his natural history, knowing that he could not always come up to the standards of legitimate interpretation.
