Recent studies, particularly by Fenner, suggests that earlier recommendations of average generation lengths of 25 years or less are inappropriate, even for pre-historic societies. Devine's "rule-of-thumb" that males typically span 3 generations per century, which is the same as the "genealogical law of three generations" quoted by Tetushkin (. an average generation length of 33 years) and females generations per century (. an average generation length of 29 years) appears to be a useful and reasonable tool for both genetic and conventional genealogy. But, as Borges rightly emphasises, individual pedigrees may have generation rates very different to these averages.
where f is any invertible function. The harmonic mean is an example of this using f ( x ) = 1/ x , and the geometric mean is another, using f ( x ) = log x .

It had long been realised that a universal standard of measurement was needed, and that it should be a natural constant. In 1791 the French National Assembly decided in favour of a standard that would be one ten millionth part of a quarter of the earth's circumference. The survey which established the length was made from Dunkirk, in France, to Barcelona, in Spain. The work was long and difficult and was carried out during a time when France and Spain were heading to war. On a number of occasions the surveyors were arrested as spies and nearly lost their heads! From this survey a platinum 'end bar' was produced in 1799 which was known as the 'Mètre des Archives' and was the master standard for the world's new measuring system, the so-called metric system.
