| Description | Discusses the ‘French’ or ‘Parisian’ problem, as set by François Dulaurens.
The problem, as understood by John Wallis, was as follows: 'given in number the circle CBD with radius CB, and the inscribed line BD protracted as far as may be desired beyond the circle, yet so that BY drawn parallel to CF may cut the circle in Y. To find the true value of the line BY, not an approximation (which may easily be obtained from a table of sines)'.
