from that time, these substances must undergo, more or less, 

 great changes, according to the intensity of the heat which the 

 compression develops in the air. In the red and black dust, 

 the oxide of iron is probably the principal colouring matter. In 

 the black dust, there is no doubt carbon will also be found. I 

 consider the black and very friable stones which fell at Alais in 

 1806, as affording the passage from the black dust to common 

 meteorites, the heat not having been sufficient to burn the 

 carbon of these stones and fuse the other substances.
