1292. Notwithstanding the striking contrasts of all kinds 

 which these gases present of property, of density, whether 

 simple or compound, anions or cathions (665.), of high or 

 low pressure (1284. 1286.), hot or cold (1288.), not the least 

 difference in their capacity to favour or admit electrical in- 

 duction through them could be perceived. Considering the 

 point established, that in all these gases induction takes place 

 by an action of contiguous particles, this is the more im- 

 portant, and adds one to the many striking relations which 

 hold between bodies having the gaseous condition and form. 

 Another equally important electrical relation, which will be 

 examined in the next paper, is that which the different gases 

 have to each other at the saine pressure of causing the reten- 

 tion of the same or different degrees of' charge upon conductors 

 in them. These two results appear to bear importantly upon 

 the subject of electro-chemical excitation and decomposition; 

 for as all these phaenomena, different as they seem to be, must 

 depend upon the electrical forces of the particles of matter, 

 the very distance at which they seem to stand from each other 

 will do much, if properly considered, to illustrate the prin- 

 ciple by which they are held in one common bond, and sub- 

 ject, as they must be, to one common law. 



1293. It is just possible that the gases may differ from each 

 other in their specific inductive capacity, and yet by quan-»
