    Re: sextants and micrometers

    George-
     Were micrometers at all available in their time? Could htey simply have used 
    a small micrometer to measure the exact scale reading, literally by placing 
    it alongside the scale instead of using an eyeball judgement?
     This could be a simple logic of economics, i.e. buying a "stock" small 
    micrometer rather than a more expensive and complex sextant of a design which 
    perhaps had not been made?
