    Then this is the same book I read:-)
    I just forgot the name of the author.
    If you type on Google "Delambre and Mechain"
    you get several pages about this.
    These pages are mostly run by the opponents of the metric
    As if precise measurement of a meridian had anything to do
    with the matter. The advantages of the metric system are certainly
    not in the precise relation
    between the meter and some meridian.
