  The method used by senior geodetic engineer Jean-Georges Affholder to
determine what can be termed as the 'centre of gravity' of physical Europe in
1989 and 2004 relies on mathematical formulae which, in their only published
version, happen to be flawed with typographical errors that do not reflect Mr.
Affholder's actual mathematical exactness. This short epistemological paper
summarizes the major steps of Affholder's method, provides a corrected version
of the general formulae, and briefly recalls some particulars of the specific
determination of the centre of gravity of physical Europe.
