   {Purge}.]
   1. The act of purging; the act of clearing, cleansing, or
      putifying, by separating and carrying off impurities, or

   2. (Law) The clearing of one's self from a crime of which one
      was publicly suspected and accused. It was either
      canonical, which was prescribed by the canon law, the form
      whereof used in the spiritual court was, that the person
      suspected take his oath that he was clear of the matter
      objected against him, and bring his honest neighbors with
      him to make oath that they believes he swore truly; or
      vulgar, which was by fire or water ordeal, or by combat.
      See {Ordeal}. --Wharton.
      [1913 Webster]

            Let him put me to my purgation.       --Shak.

from Bouvier's Law Dictionary, Revised 6th Ed (1856)
PURGATION. The clearing one's self of an offence charged, by denying the 
guilt on oath or affirmation. 
     2. There were two sorts of purgation, the vulgar, and the canonical. 
     3. Vulgar purgation consisted in superstitious trials by hot and cold 
water, by fire, by hot irons, by batell, by corsned, &c., which modes of 
trial were adopted in times of ignorance and barbarity, and were impiously 
called judgments of God. 
     4. Canonical purgation was the act of justifying one's self, when 
accused of some offence in the presence of a number of persons, worthy of 
credit, generally twelve, who would swear they believed the accused. See 
Compurgator; Wager of Law. 
     5. In modern times, a man may purge himself of an offence, in some 
cases where the facts are within his own knowledge; for example, when a man 
is charged with a contempt of court, he may purge himself of such contempt, 
by swearing that in doing the act charged, he did not intend to commit a 
contempt.
