in our old customs, silver coin, or pieces of bullion that anciently passed for money. By Doomsday tenure, some rents to the king were paid in argento albo, common silver pieces of money; other rents in libris urbis et penates, in metal of full weight and purity: in the next age, that rent which was paid in money, was called blancb fearm, and Argentum and afterwards subite rent; and what was paid in provisions, was termed black mail.

Argentum Dei, God's penny, anciently signified earnest money, or money given to bind a bargain; in some places called erler, or arler, and by the civilians and canonists, arrhe. Et capit de praedicto Henrico tres denarios de argenti Dei prae manibus.

Argentum Mythum is a metal consisting of silver-like flakes, used for the colouring of platter figures, and for other purposes, as pigment. It consists of an amalgam of equal parts of tin, bismuth, and mercury. It is to be mixed with white of eggs, or spirit varnish, and then applied to the intended work, which is afterwards to be burnished.

Argentum Vivum, Mercury, or Quicksilver. See Mercury and Chemistry Index.
