Excerpt from Exposition Et Histoire des Principales D???couvertes Scientifiques Modernes, Vol. 3: T???l???graphie A???rienne Et ???lectrique; Galvanoplastie Et Dorure Chimique; Photographie; Poudres de Guerre Et Poudre-Coton Peut - ???tre, dit Fontenelle, prendra - t - on pour un jeu d'es prit, mais du moins tr???s - ing???nieux, un moyen qu'il inventa de faire savoir tout ce qu' on voudrait ??? une tr???s-grande distance, par exemple de Paris ??? Rome, en tr???s - peu de temps, comme en n 013 ou quatre heures, et m???me sans que la nouvelle f???t sue dans tout l'espace d'entre - deux. Cette proposition, si paradoxe et si chim???rique en apparence, fut ex???cut???e dans une petite ???tendue de pays, une fois en pr???sence de Monseigneur, et une autreen pr???sence de Madame. Le secret consistait ??? disposer dans plu sieurs postes cons???cutifs des gens qui, par des lunettes de longue vue, ayant aper???u certains signaux du poste pr???c???dent, les transmisent au suivant, et toujours ainsi de suite, et cesgdifi'??? rents signaux ???taient autant de lettres d'un alphabet dont on n 'avait le chifi're qu '??? Paris et ??? Rome. La plus grande port???e des lunettes faisait la distance des postes, dont le nombre devait ???tre le moindre qu 'il f???t possible; et comme le second poste fai sait des signaux au troisi???me ??? mesure qu 'il les vovait faire au premier, la nouvelle se trouvait port???e ??? Rome presque eu aussi peu de temps qu 'il en fallait pour faire les signaux ??? Paris. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
