(26) Cobaltic acid is aie in combination with ammonia, when that alkali is

27) The black oxide of iron, considered as a combination the black and red 
oxides, Berzelius calls ferroso-ferric oxide. In thus adopting the Latin termination 
for the first of the two names, he takes ee not ee in his own remar 
as given by the French translator, but in which he is abundantly borne out by anal- 
ogy. i te 73 
(28) The red oxide Berzelius calls manganoso-man ganic oxide. The names ve 
these oxides are derived from that for manganese, stated by the author to be used by

he emists, viz. manganium. his name prevents confusion between 
estum and its compounds, and manganesium and its combinations. Its

solved manganate: its salts are isomorphous with the oxychlorates.—Trans
