  And I shall proceed to consider the testimony of Experience, when I shall have first advertis'd You, that if Men were as perfectly rational as 'tis to be wish'd they were, this sensible way of Probation would be as needless as 'tis wont to be imperfect.
  1661, Robert Boyle, The Sceptical Chymist, page 20
  And then it started like a guilty thing / Upon a fearful summons. I have heard, / The cock, that is the trumpet to the morn, / Doth with his lofty and shrill-sounding throat / Awake the god of day; and, at his warning, / Whether in sea or fire, in earth or air / The extravagant and erring spirit hies / To his confine: and of the truth herein / This present object made probation.
