It was published in the first series of _Essays_, which appeared in 1841.] [Footnote 661: Lubricity. The word means literally the state or quality of being slippery; Emerson uses it several times, in its derived sense of "instability."] [Footnote 662: Love and Friendship. The subjects of the two essays preceding _Prudence_, in the volume of 1841.] [Footnote 663: The world is filled with the proverbs, etc. Compare with this passage Emerson's words in _Compensation_ on "the flights of proverbs, whose teaching is as true and as omnipresent as that of birds and flies."] [Footnote 664: A good wheel or pin. That is, a part of a machine.] [Footnote 665: The law of polarity. Having two opposite poles, the properties of the one of which are the opposite of the other.] [Footnote 666: Summer will have its flies.

In this, as in many other instances, Emerson quotes from his memory instead of from the book. The words of Dr. Johnson, as reported by his biographer Boswell, are: "Accustom your children constantly to this; if a thing happened at one window, and they, when relating it, say it happened at another, do not let it pass, but instantly check them; you do not know where deviation from truth will end."] [Footnote 670: Rifle. A local name in England and New England for an instrument, on the order of a whetstone, used for sharpening scythes; it is made of wood, covered with fine sand or emery.]
