    Jared,
    
    You said, among other things, "I think many of us (myself included!) have
    some conceptual problems caused by the way we have learned basic terms and
    concepts."
    
    I agree. I believe that's what made it hard for most people to accept the
    idea of using calculated altitudes to work lunars. I also believe it's what
    has made the old nautical astronomy incomprehensible to twentieth century
    navigators.
    
    The old system was pretty much upside down and backward from our own, and had
    to be. Moreover, it used words and phrases that had one meaning then and a
    different one now. I expect the only way to learn how the navigators of
    Bowditch's day thought is to work their problems the way they did. Then, with
    luck, the old view will become clear.
    
    Bruce
