| | Benjamin Vaughan on the Washington Meridian, 1811 |
 | | Pene, [Jean Dominique] Cassini, and others in their great Neptune Français [1693], continued to obey its injunctions at the close of the seventeenth century, as did M [Jean-Baptiste] d'Anville (the King's geographer) even in his separate map of France, divided into provinces and generalities which was published so late as 1780. |
 | | M Cassini had an opportunity of trying this experiment afterwards in the south of France in the winter of 1739-1740, with a little variation, for the observers were stationed on 2 heights, while the pounds of powder were fired from the top of a church in a valley below. |
 | | M de la Condamine and his colleagues had no opportunity to make experiments at the equator as to longitudes, since they were released, while there, from the last part of their commission which related to that object. |
