III.i.71 (461,7) come, Fate, into the list,/And champion me to the utterance!] This passage will be best explained by translating it into the language from whence the only word of difficulty in it is borrowed, “Que la destinee se rende en lice, et qu’elle me donne un defi a l’outrance.”  A challenge or a combat a l’outrance, to extremity, was a fix’d term in the law of arms, used when the combatants engaged with an odium internecinum, an intention to destroy each other, in opposition to trials of skill at festivals, or on other occasions, where the contest was only for reputation or a prize.  The sense therefore is, Let Fate, that has foredoom’d the exaltation of the sons of Banquo, enter the lists against me, with the utmost animosity, in defence of its own decrees, which I will endeavour to invalidate, whatever be the danger. [Johnson quotes Warburton’s note] After the former explication, Dr. Warburton was desirous to seem to do something; and he has therefore made Fate the marshal, whom I had made the champion, and has left Macbeth to enter the lists without an opponent.

III.i.88 (462,9) Are you so gospell’d] Are you of that degree of precise virtue? Gospeller was a name of contempt given by the Papists to the Lollards, the puritans of early times, and the precursors of protestantism.

III.i.94 (463,1) Showghes] Showghes are probably what we now call shocks, demi-wolves, lyciscae; dogs bred between wolves and dogs. (1773)

III.i.95 (463,2) the valued file] In this speech the word file occurs twice, and seems in both places to have a meaning different from its present use.  The expression, valued file, evidently means, a list or catalogue of value.  A station in the file, and not in the worst rank, may mean, a place in the list of manhood, and not in the lowest place.  But file seems rather to mean in this place, a post of honour; the first rank, in opposition to the last; a meaning which I have not observed in any other place. (1773)

III.i.112 (465,2) So weary with disasters, tug’d with fortune] Tug’d with fortune may be, tug’d or worried by fortune.

III.i.130 (465,4) Acquaint you with the perfect spy o’ the time] What is meant by the spy of the time, it will be found difficult to explain; and therefore sense will be cheaply gained by a slight alteration.—­Macbeth is assuring the assassins that they shall not want directions to find Banquo, and therefore says,

  I will—­
  Acquaint you with a perfect spy o’ the time.

Accordingly a third murderer joins them afterwards at the place of action.

Perfect is well instructed, or well informed, as in this play,

  Though in your state of honour I am perfect.

though I am well acquainted with your quality and rank. [Warburton explained this as “the critical juncture”] How the critical juncture is the spy o’ the time I know not, but I think my own conjecture right.
