Récit d'une grande boule de feu vue à Poggio Ubertini, près de Florence (extrait d'une lettre de Madame Baldelli):—

"Le 1^er du mois dernier (novembre), errant dehors après la tombée de la nuit, j'ai vu vers 11 heures moins 6, en direction de l'étoile polaire, une des apparitions météoritique les plus remarquables en plein ciel que j'aie jamais vue (et j'en ai vues de très curieuses). A white globe of fire many times larger than the full portion of the surrounding heavens was lighted up by it, so much so that my head being turned away from it, I mechanically apprehended it was moonlight, though, had I though at all, I should have known that no moon was at that time in sight ; but a bright shimmering of light on a tall bay tree not far from me recalled my attention, and turning I saw this fireball, white for a moment, shades of orange and blue passing over its surface, the latter gaining on the former. After a full minute's time (after I had turned towards it) it disappeared suddenly—vanishing, not appearing to move from where it was; only just before its disppearance a smaller ball was seen immediately below it, of a fiery orange colour, the first one appearing at the moment of the same hue. I called Baldelli often whilst looking at it, but he had left the drawing-room, which opened on the grounds, and did not hear me. The servants in the kitchen (also on the ground-floor, but far away from where I was) thought the bright light came from sheet lightning."
