  • lists this only as an alternative for duct, but this is from a recent message on the VMS List: 'Modern forensic graphology, usually used to detect forgeries, is for the most part, dependent upon ductus; that is the direction, pressure, and order in which strokes are laid down. No two people, even when producing visually identical letters will construct those letters with exactly the same ductus.'

    The OED has 'the method of making strokes with the pen, etc.' and identifies it with its fourth definition for duct: 'A stroke drawn or traced, or the manner of tracing it (cf. L. ductus litterarum).'
