ARGENTUM DEI, God's penny, anciently signified earnest money, or money given to bind a bargain; in some places called erles, or arles, and by the civilians and canonists, arrhæ. Et cepit de prædicto Henrico tres denarios de argenti Dei præ manibus.
ARGENTUM MUSIVUM is a mass consisting of silver-like flakes, used for the colouring of plaster 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.
