By analogous modes of reduction, the following results 
were deduced from my experiments. I ought here to state, 
that in many cases the materials, after being ignited in the 
tube, and then cooled, were again triturated in the mortar, 
and subjected to a second ignition. Thus, none of the carbon 
could escape conversion into carbonic acid. I was seldom 
content with one experiment on a body ; frequently six or 
eight were made.
