    Re: Newton and Halley
    From: George Huxtable

    Mike Daly added the following, to his posting 3927-
    Charles H. Cotter,  "The Mariner's Sextant and the Royal Society" Notes
    and Records of the Royal Society of London, Vol. 33, No. 1 (Aug., 1978),
    p. 31:
    "There is no evidence, however, that Newton's instrument materialized,
    let alone that it was tested at sea."
    And I replied,
    I'm not sure what view Mike is pushing here. Is he really trying to convince
    us, against all the evidence, that Newton's quadrant never even existed?
    Whether Mike Daly thinks that or not, that quotation undermines Cotter as
    any sort of witness, because by 1983, Cotter has dropped any such claim for
    its non-existence.
    In Navlist 3966, Mike Daly asked for the source of what I had written above;
    which is a fair question.
    The Cotter work I was referring to was his "History of the Navigator's
    Sextant", of 1983, which I had referred to before. But Mike's enquiry sent
    me back to check it, and indeed, at second reading, I now find those exact
    same words, on page 107.
    I was wrong. Sorry about that. Cotter remained consistent.
    On request, I will happy to attach scans of the relevant 3 pages from
    contact George Huxtable at george@huxtable.u-net.com
    or at +44 1865 820222 (from UK, 01865 820222)
    or at 1 Sandy Lane, Southmoor, Abingdon, Oxon OX13 5HX, UK.
