 by the complete confutation, the appropriate modification, or the 

 ultimate establishment, of the premises here set forth. 



This little work contains, as a necessary appendage, a condensed 

 review of the opinions of the most celebrated for Science, in the earlier 

 and present times, who have expressed their sentiments on the subject: 

 and refers, with due acknowledgments, to the accurate experiments of 

 many Authors of the highest authority (particularly of the present day), 

 for corroborating facts, as it is hoped, deducible in support of this

 concretions from the residium of gases, ignited by electric 

 currents in our atmosphere, being occasioned by surplus 

 portions of one or more of the original gases acting as a nucleus, 

 and which have no opportunity to unite in the prescribed order 

 of polarity, for the formation of radiant matter.

The answer is (by implication), they would be so discovered, but 

 that there is not any SOLID body in existence, established as homo- 

 geneous.
