CHEMICAL PHENOMENA OF IRON SMELTING. An ex
perimental and praetical examination of the circumstances which
determine the capacity of the Blast Furnace, the Temperature
of the Air, and the Proper Condition of the Materials to be
operated upon. By I. Lowthian Bell.
u The reactions which take place in every foot of the blast-furnace have
been investigated, and the nature of every step in theprocess, from the intro-
duction of the raw material into the furnace to the production of the pig iron,
has been carefully ascertained, and recorded so fully that any one in the trade
can readily avail themselves of the knowledge acquired; and wo have no hes-
itation in saying that the judicious application of such knowledge will do
much to faeilitate the introduction of arrangements which will still further
economize fuel, and at the same time permit of the quality of the resulting
metal being maintained, if not improved. The volume is one which no prac-
tical pig iron manufacturer can afford to be without if he be desirous of en
tering upon that competition which nowadays is essential to progress, and
in issuing such a work Mr. Bell has entitled himsolf to the best thanks of
every member of the trade.”—London Mining Journal.
