    Ironic since Thompson is justifiably famous for defending the native's
    religion and customs as equally valid for their culture as Christianity
    was for Europeans. Thompson's "Narrative" reads like that of a
    professional ethologist. I get the sense that McGoogan's Thompson is
    similar to Dava Sobel's Maskelyne--deliberately cast as villains to foil
    their respective heroes.

    In the above I should have said he had an opportunity to learn lunars,
    rather than navigation, from Wales and Dymond.

    But could he have been trained in lunar distances for longitude at that
    time (1762), without an almanac, tables, or methods reduced to practice?
    Surely only an astronomer who could calculate everything (including the
    position of the moon) would have been able to do it. I think Maskelyne's
    British Mariner's Guide came out in 1763 and the Nautical Almanac was
    started a few years later.Since Wales was the principal computer for the
    newly begun nautical almanac, it seems likely that he would have carried
    one with him in 1768, along with Maskelyne's British Mariner's Guide.
    Hearne could have copied some of the necessary data, I suppose, but any
    lunars he did take with his old quadrant couldn't possibly have given him
    a decent longitude (given that his latitude was out by 450 km).
    
    Perhaps there are other listmembers who could weigh in with more knowledge
    of the state of longitude measurements in the early 1760s.

    Indeed; an accomplishment that establishes his navigational skill as top
    notch. At any rate, I shouldn't be so quick to judge McGoogan's book
    without having read it. I'll pick it up this week and see what he has to
    say.
