rente." The following conclusions are presented as those 

 drawn by M. Bellevue : 



1. The appearances presented by the crust of meteor- 

 elites, seem to prove that their surface has been fused whilst 

 rapidly traversing the flame of the meteor, and rapidly so- 

 lidified into a vitreous state on leaving that flame. 



2. They prove that in the first moments, the movement 

 of the meteorolites was simple, that is, that they did not 

 turn round on their own axis, whilst those two effects took 

 place. 



3. That the impulse each meteorolite has received has al- 

 most always been perpendicular to its largest face. 



4. That the largest face is almost always, more or less, 

 convex. 



5. Our meteorolites (those of Jonzac) offer new proofs 

 of the pre-existence of a solid nucleus, to bolides or me- 

 teors. 



6. This nucleus could not contain the combustible mat- 

 ter which produced the inflammation of the meteor. 



7. It cannot have suffered fusion during the appearance 

 of the phenomena. 



8. The gaseous matter, which surrounds this nucleus, is 

 dissipated without producing any solid residuum. No trace 

 of this matter appears ever to exist in the crust of the me- 

 teoroliteSj. 



9. Meteorolites are fragments of those nuclei which have 

 not been altered in their natures, but simply vitrified at their 

 surfaces. 



10. Many of the irregular forms which these fragments 

 present, may be referred to determinate geometric forms. 



11. These latter forms are the consequences of the rapid 

 action of a violent fire, according to a law of the movement 

 of heat in solid bodies, discovered by M. Emen.
