~ chemical constitution has either suffered, from atmospheric in- 
fluences, a total decomposition, or at least become so much al- 
tered.as no longer to be distinguishable. This arrangement of 
meteoric elements, like that given above, is constructed from a 
view of the totality of meteor-masses at present known to be 
in existence, on the surface of our globe. The terrestrial ele- 
ments being arranged also as nearly as possible in the order of 
their abundance, the correspondence they sustain to the meteoric 
group, will at once be discerned by a reference to the numbers by 
which one and the same element is preceded on the two lists. 
The seven elements, among the twenty-eight terrestrial series, 
not | me detected in meteors, are followed each by a star.
