MDDM Ch.72 A Slouch Hat..."Well met"

[Bandwraith at aol.com]

[704.32]

        They are approach'd by a Gentleman
    not quite familiar to them. A Slouch Hat
    obscures much of his Face. "Well met,"
    he pronounces, yet nothing further.

and, [705.8]

    "There is a Falmouth invisible, as the center
    of a circle is invisible, yet with Compasses
    and Straight-Edge may be found."

Pretty sure this is a visitation by the jesuit and
mathematician Gregorius Saint Vincent,1584-1667, See:
