    I had asked Frank Reed, after he admitted being a physicist specialising in
    "Frank, where were you a few months ago when the list was wrangling over
    the question of the dips and bumps in the Earth's gravitational field (and
    whether you could shorten a passage by navigating around them)?"
    and Frank replied-
    Can you point me to the right spot in the message archives? I would love to
    see how the discussion turned out.
    That thread was started by David Hoyte on 13 August and named "Navigating
    around hills and dips" and ended up (by him and me) on 30 August under-
    "Reality Check: Navigating Around Hill and Dips". Some contributions may
    have been under different (but associated) thread-names.
    In response to an inquiry about the Centennia Historical Atlas, he replied-
    "Since it's a commercial product, I don't think I should spend time on it
    on this list"
    Frank's reservations are admirable, but we are accustomed to, and accept,
    list-members pushing their own books where they are relevant. The
    Historical Atlas might well be of some interest to members. But otherwise,
    if Frank's scruples get the better of him, and he has information he can
    send out as e-mail, I would welcome a copy sent directly to my email
    Later, Frank said-
    "There's a funny quote in a navigation textbook from c.1905 (by the Earl of
    Dunworthy??). His chapter on lunars begins with a long explanation of why
    lunars are "a foolish thing" but a "fascinating mathematical problem"."
    It was in vol.3 of "Practice and theory of navigation" (2nd ed. 1908) by
    the Earl of Dunraven, who had achieved an extra master's ticket. This was
    mainly a course-book for the Board of Trade exams. I have vols 1 and 3 and
    am seeking vol 2.
    It's clear we are going to enjoy Frank Reed's membership.
