Messrs. Brin believe they have
overcome the first obstacle, and are addressing themselves, we
believe, to the removal of the second. Again, the intense heat which
the combustion of carbon in cheap oxygen will place at the disposal of
the metallurgist cannot fail to play an important part in his
operations. There are many processes, too, of metal refining which
ought to be facilitated by the use of the gas. Then the production of
pure metallic oxides for the manufacture of paints, the bleaching of
oils and fats, the reduction of refractory ores of the precious metals
on a large scale, the conversion of iron into steel, and numberless
other processes familiar to the specialists whose walk is in the
byways of applied chemistry, should all profit by the employment of
this energetic agent. Doubtless, too, the investigation into methods
of producing the compounds of nitrogen so indispensable as plant
foods, and for which we are now dependent on the supplies of the
mineral world, may be stimulated by the fact that there is available
by Brin's process a cheap and inexhaustible supply of pure
nitrogen.--_Industries._
