A recent French process for obtaining anti
mony from its ores is announced. the method
consisting in treating sulphide Of antimon7
with certain salts of oxide OF iron alone. or in
connection with ha!oid salts. in an apparatus
from which the anthony is deposited cleo
trolyticallr. The trisu!phide OF anthony is
decomrosed in contact with fcrric salts. sui
the state OF ferrous oxide. and at the same
time antimonious oxide passes into solution.
The reaction is rapid; and is complete when i
ch!oric acid. or. more iavorably. in this pres
ence Of a halGid salt. such as common SAL.
phur by filtration. Is submitted to elcctroly,i:
action. and the anthony !? preclpitated at he
positive pole. giving a solution OF ferric chic:

Much is claimed for an improved device in
cotton spinning: that is. by q new method. the
forming Of cops on spindles without spindles re-
volving is accomplished bI mounting the cop
spindles in a frame having up-and-down mo-
lions. regulated by any copping motion. Ac-
cordinG to this arrangement. anove the framei Is
liked a rail. In which Is mounted over each spin
die tubular bearing. TO which Is attached any
driving medium and a disk carrying a tyer by

The convenience OF obtaining small power In
industrial operations Is now greatly facilitated
by the introduction ola peculiar form ofvertical
marine and semi'portallo engine and boiler.the
advantage pertaining to this form Of construc-
ton being thft it is imnossihle for the engine

An ingenious Process for Iroduring white
and red designs on indigo dyed goods is based
on the destruction OF indigo by nascent bro
mine. obtained by acting with strong acids on
mixtures OF bromide and bromate Of soda. or
on bromide Of soda and chlornt- OF a,unina.
