    Re: Pillar sextant: what's in a name?

    George you asked:
    "Does he know of ANY such reference in the literature to such an adaptation
    of the sextant on a stand, under any other name, then?"
    A sextant on a stand is not called a "pillar sextant". It's called a sextant
    on a stand. Sometimes the stand is called a "pillar stand" which is
    undoubtedly where the confusion comes from. So you can have a "sextant on a
    pillar stand" [which is not a pillar sextant] and even a "pillar sextant on
    a pillar stand" [which remains a pillar sextant even when you take it off
    the stand]. So you might ask, "how can I research the evolution of a
    technical term without leaving the comfort of your favorite chair?" I'm glad
    you asked that! Here's how: go to the Google Books Advanced Search page
    and where it says "with the exact phrase" enter "pillar sextant" (quotes not
    necessary in this field). You may want to select "Full View" books but there
    are some good references under "Limited Preview" too. Google will then
    happily search through thousands upon thousands of books for that special
    phrase. Have fun.
    PS: the above procedure naturally works for other navigational phrase and
    it's a really good way to find other books on navigation. Yesterday, I
    searched on "line of position". Before the end of the 19th century, this had
    two common meanings: a military line and the line of tilt in penmanship.
