                                Diagram in a letter from Renatus Franciscus Slusius to Henry Oldenburg dated 22 November 1673, concerning the centrobaric rule of Paul Guldin (1577-1643). Guldin’s rule in Centrobaryca (1635-41) states that, ‘if any plane figure revolve about an external axis in its plane, the volume of the solid so generated is equal to the product of the area of the figure and the distance travelled by the center of gravity of the figure’ (as explained in The Correspondence of Henry Oldenburg, vol. 10, p. 180n4).
