Meteorites, or Celestial Stones: French

The influence exerted by popular beliefs, even upon the learned, is well illustrated by the opinion given by some of the leading French physicists of the eighteenth century as to the character of meteorites. When a meteoric stone fell at Luce, Dept. Marne, France, September 13, 1768, three French scientists, among them the celebrated Lavoisier, were sent to investigate the matter. In their report to the Academy of Sciences, they state that there must have been some error in the accounts given of the event, for it was an assured fact that no such things as pierres de foudre, or thunder-stones, existed. This was, of course, perfectly true, but Lavoisier and his companions did not stop to think that stones might fall to the earth in some other way. The result of the investigation was summed up as follows: If the existence of thunder-stones was regarded as doubtful at a time when physicists had scarcely any idea of the nature of thunder, it is even less admissible to-day, when modern physicists have discovered the effects of this natural phenomenon are the same as those of electricity. There is no record that the fulgarite, the fused sand or rock struck by the lightning, has ever been used.

The opinion which seems the most probable to us, and that which is most in accord with the accepted principles of physics as well as with the facts reported by Abbe Bacheley, and our own investigation, is that the stone was originally covered with a slight crust of earth and turf, and was struck by lightning and so made visible.
