The same respect for the truth distinguished the Bureau des Longitudes . The provinces were slightly more affirmative . Perhaps in the night of the fifth and the morning of the sixth of May there had appeared a flash of light of electrical origin which lasted about twenty seconds . At the Pic du Midi this light appeared between nine and ten in the evening . At the Meteorological Observatory on the Puy de Dome the light had been observed between one and two o'clock in the morning ; at Mont Ventoux in Provence it had been seen between two and three o'clock ; at Nice it had been noticed between three and four o'clock ; while at the Semnoz Alps between Annecy , Le Bourget , and Le Léman , it had been detected just as the zenith was paling with the dawn . Now it evidently would not do to disregard these observations altogether . There could be no doubt that a light had been observed at different places , in succession , at intervals , during some hours .
