It was then half-past three in the afternoon. The projectile was following its curvilinear direction round the moon. Had its course again been altered by the meteor? It was to be feared so. But the projectile must describe a curve unalterably determined by the laws of mechanical reasoning. Barbicane was inclined to believe that this curve would be rather a parabola than a hyperbola. But admitting the parabola, the projectile must quickly have passed through the cone of shadow projected into space opposite the sun. This cone, indeed, is very narrow, the angular diameter of the moon being so little when compared with the diameter of the orb of day; and up to this time the projectile had been floating in this deep shadow. Whatever had been its speed (and it could not have been insignificant), its period of occultation continued. That was evident, but perhaps that would not have been the case in a supposedly rigidly parabolical trajectory—a new problem which tormented Barbicane's brain,imprisoned as he was in a circle of unknowns which he could not unravel.
