    Re: History of the sextant.

    I wonder if Mrs Janet Taylor (c. 1837) is in any way related to E.G.R. Taylor?
    I have a book entitled "The Haven-Finding Art: A History of Navigation from
    Odysseus to Captain Cook" by E.G.R. Taylor, Emeritus Professor of Geography,
    London University, Hon. Member of the Institute of Navigation.  This book
    was published in London by Hollis & Carter in 1956.  In the forward the
    author says "the author acknowledges.. and offers her thanks" -- showing
    that the author was a woman as well.  How many Taylor women could there
    be with this much devotion to navigation?  Not too many is my guess.
    W.E. May in his 1973 book "A History of Marine Navigation" mentions the
    late E.G.R. Taylor and in the index we learn that E.G.R. stands for
    Eva Germaine Rimington.
    I would really be interested in seeing Mrs Janet Taylor's Mariner's
    Calculator.  That sounds like a fascinating invention.
    I too have Cotter's "A History of the Navigator's Sextant", as well as
    his "The Complete Nautical Astronomer" and "The Elements of Navigation"
    but I have repeatedly had no luck in finding his "A History of Nautical
    Astronomy" that you refer to so often.

    Subject: History of the sextant.
    I have recently acquired a copy of "A history of the navigator's sextant",
    by Charles H Cotter, pub. 1983 by Brown, Son, and Ferguson, Glasgow.
    I wasn't previously aware of the existence of this book, and don't recall
    having seen a reference to it in this or any other mailing list, so this
    note is to bring it to the attention of list members. It seems to be still
    in print, 226 pages, at �20.
    Cotter is best known for his "A history of nautical astronomy" of some 20
    years earlier, now increasingly hard to find.
    His book on the sextant is really comprehensive, ranging from the mariner's
    astrolabe through to the bubble sextants designed for air navigation. I
    have discovered many facts previously unknown to me. There are lots of
    It has many intriguing diversions, such as those about Mrs Janet Taylor,
    who ran a navigation school in the Minories, London, and wrote a book, "The
    principles of navigation simplified", in 1837. How did she gain her
    experience? one wonders. She produced the Mariner's Calculator, illustrated
    in that book, which combined a sextant with a precise analogue computer,
    for solving astronomical-triangle problems, and also brought out an
    Artificial Horizon attachment to a sextant in 1856. I'm keen to discover
    more about Mrs Janet Taylor.
