Divided into two parties in order thus to obtain two measurements instead of one, and thereby also to diminish the chance of mistakes, the adventurous savants, after inconceivable hairbreadth escapes, of which an account can be found in the Memoirs of the Academy of Sciences for 1737, and after incredible efforts, decided that the length of the meridian circle, comprised between the parallels of Tornea and Kittis was 55,023 fathoms and a half. Thus below the Polar circle, the meridian degree comprised a thousand fathoms more than Cassini had imagined, and the terrestrial degree exceeded by 377 fathoms the length which Picard has reckoned it between Paris and Amiens.
The result, therefore, of this discovery (a result long repudiated by the Cassinis, both father and son), was that the earth was considerably flattened at the poles.
Voltaire somewhat maliciously said of it,—
| Courrier de la physique, argonaute nouveau, Qui, franchissant les monts, qui, traversant les eaux, Ramenez des climats soumis aux trois couronnes, Vos perches, vos secteurs et surtout deux Laponnes. Vous avez confirmé dans ces lieux pleins d'ennui Ce que Newton connut sans sortir de lui. |
In much the same vein he alludes to the two sisters who accompanied Maupertuis upon his return, the attractions of one of whom proved irresistible,—
| Cette erreur est trop ordinaire Et c'est la seule que l'on fit En allant au cercle polaire. |
M. A. Maury in his "History of the Academy of Sciences," remarks,—
"At the same time, the importance of the instruments and methods employed by the astronomers sent to the North, afforded a support to the defenders of the theory of the flattening of the globes, which was hardly theirs by right, and in the following century the Swedish astronomer, Svanburg, rectified their involuntary exaggerations, in a fine work published by him in the French language."
Meantime the mission despatched by the Academy to Peru proceeded with analogous operations. It consisted of La Condamine, Bouguer, and Godin, three Academicians, Joseph de Jussieu, Governor of the Medical College, who undertook the botanical branch, Seniergues, a surgeon, Godin des Odonais, a clock-maker, and a draughtsman. They started from La Rochelle, on the 16th of May, 1735.
Upon reaching St. Domingo, they took several astronomical observations, and continued by way of Porto Bello, and Carthagena. Crossing the Isthmus of Panama, they disembarked at Manta in Peru, upon the 9th of March, 1736.
