    In an earlier mailing today, replying to Sharon Casey, I said-

    >Above an underwater sea-mount made of lead, there would be an increase in
    >gravity, and >the sea-level would be a bit lower there than it would be if
    >the lump of lead was absent.

    Thinking about it a bit harder, and perhaps a bit more clearly, it now
    seems to me that I got the last bit quite wrong and should really have
    said-

    "Above an underwater sea-mount made of lead, there would be an increase in
    gravity, and the sea-level would be a bit higher there than it would be if
    the lump of lead was absent."

    That error doesn't affect anything else in the argument, but it's better to
    get these things right rather than wrong.

    George.
