    And that is where his argument fails, as Alex has pointed out.
    If there were no further anomalous refraction, the angular anomaly would
    remain unchanged, from when that light-ray whizzed past my head, for as
    long as it continued to travel.
    I should add that I have no idea, at all, of the range of heights above the
    water surface over which anomalous dip occurs.
