'And again _those differences_ which proceed from FORTUNE, as SOVEREIGNTY, NOBILITY, OBSCURE BIRTH, RICHES, WANT, MAGISTRACY, PRIVATENESS, PROSPERITY, ADVERSITY, constant fortune, variable fortune, rising _per saltum, per gradus_, and the like.' These are articles that he puts down for points in his _table of natural history_, points for the collection of instances; this is the tabular preparation for induction here; for he does not conclude his precepts on the popular, miscellaneous, accidental history. That will do well enough for books. It won't do to get out axioms of practice from such loose material. They have to ring with the proof of another kind of condensation. All _his_ history is artificial, prepared history more _select_ and _subtle_ and _fit_ than the other kind, he says,--prepared on purpose; perhaps we shall come across his tables, some day, with these very points on them, filled in with the observations of one, so qualified by the truth of direction to make them 'severe'. It would not be strange, for he gives us to understand that he is not altogether idle in this part of his Instauration, and that he does not think it enough to lay out work for others, without giving an occasional specimen of his own, of the thing which he notes as deficient, and proposes to have done, so that there may be no mistake about it as to what it really is; for he appears to think there is some danger of that. Even here, he produces a few illustrations of his meaning, that it may appear the better what is, and whether it be extant.
