    Frank,

    You quoted my remark that the Rios' method in Norie is "similar to Bowditch's
    original method, before that was improved by special tables, and looks to me
    to be a simplification and improvement of it."

    Then you commented: "Isn't that backwards? The method of Mendoza Rios came
    first. Moore included it in his navigation manual as the "First Method", and
    Bowditch "inherited" it, to put it politely. He later modified it slightly, but
    it's fundamentally still Don Jose's."

    Now I'm asking you to take a closer look at that method in Moore you
    attribute to Rios. You'll find it to be a version of Lions, not Rios. Moreover, it
    has, as I recall, three of those "embarrassing cases." Good method, though. I was
    using it fairly often, up to a quarter century ago.

    Bruce
