(Transcriber's Note: The 'toise' was introduced by Charlemagne
in 790; it originally represented the distance between the
fingertips of a man with outstretched arms, and is thus the same
as the British 'fathom'. During the founding of the Metric System,
less than 20 years before the date of this work, the 'toise' was
assigned a value of 1.949 meters, or a little over two yards. The
'foot'; actually the 'French foot', or 'pied', is defined as
1/6 of a 'toise', and is a little over an English foot.)
