    Re: How Many Chronometers?

    The SAO/NASA ADS site has several scanned articles on chronometer rating.
    The search page looks complicated, but you only need to enter a couple
    fields near the top. Leave everything else alone.
    • Publication Date (near the top, below Authors). Dates here are
    inclusive. For example, to search the 1850s, use 01 1850 to 12 1859.
    • Title Words. Enter "chronometer". The search engine's synonym function
    is enabled by default, so "chronometer" also finds "chronometers".
    Then click any of the Send Query buttons. A page will appear with links
    to the matching articles.
    With a low speed connection, the 3-pane window for viewing GIF documents
    is often slow because the number of thumbnail images far exceeds the
    number of pages in the article. Sometimes it seems the entire
    publication is being loaded! The solution is to click Next Page, then
    click the place where image of that next page will appear. That takes
    you to a page without thumbnails.
    The reason for clicking Next Page before you even read the first one is
    a bug in the site. If you omit this step, it says the requested page
    doesn't exist. But it's there -- you just have to go back to it from the
    second page.
    There's an odd sentence in Toynbee's November 1853 article in the
    Monthly Notices of the Royal Astronomical Society, "On Rating
    Chronometers by Lunars".
    "Late in 1850 I took the command of another ship, my chief officer
    during this voyage, on account of the delicate state of his health, was
    prevented from taking lunars."
    I knew lunars were demanding, but I didn't know they were that hard!
