The Devil's Dictionary (1881-1906):

NOSE, n.  The extreme outpost of the face.  From the circumstance that
great conquerors have great noses, Getius, whose writings antedate the
age of humor, calls the nose the organ of quell.  It has been observed
that one's nose is never so happy as when thrust into the affairs of
others, from which some physiologists have drawn the inference that
the nose is devoid of the sense of smell.

        There's a man with a Nose,
        And wherever he goes
    The people run from him and shout:
        "No cotton have we
        For our ears if so be
    He blow that interminous snout!"

        So the lawyers applied
        For injunction.  "Denied,"
    Said the Judge:  "the defendant prefixion,
        Whate'er it portend,
        Appears to transcend
    The bounds of this court's jurisdiction."
