and containing more oxygen, is called hyperchloric, signify- 

 ing higher than chloric. The other names of the list indi- 

 cate, by their prefixes and terminations, the order of oxy- 

 geriation of the several acids. The same means of distinc- 

 tion are employed in other series.

358. Sb+5Cl=SbCls.

It will be observed, on comparing 362 with those which 

 precede, that chlorine sometimes expels oxygen, and is 

 sometimes expelled by it. In relation to the apparent in- 

 consistency of these facts, litrle more can be said than that 

 chemical affinities are modified by circumstances, the action 

 of which is not perfectly understood.
