There has bcen great progress in the ap-
rlieatiou OF chemistry 70 the arts during the
Haet si1 ucnths, md VIC propose to recapitu-
late some Of the most interesting discoveries
that have been made.
Tic uses OF metallic manganese hayo flitLer-
to been confined TO the Manufacture or
peculiar kind oil crystalizable iron. xnd this
application has always Aen regarded AZ Of
nucer.ain e8INedienry. We now Lear Of An
aEoy of corrc- with ,nansaCcsc, to bo called
tapr:-Mansauese, that Appears destined TO
attract the notice o! manufacturers of naetals,
ard to give rise 10 IN important industry.
The new alloy resembles German
eIvtr -try closely, and u.ey be substituted
for it i,l must Cases. Many attempts have
leeu 1aade in times past to bring about COM
di:kt uity was to eontrive sritabia furaace ia
which sufficient hest could be economically
ou,ained to melt the manganese; thi- difficult

cia pc manufactured at much less price
than cernan silver, vlnls it POSSESSES many
properties that give it the preference over its
ancient rival. We understand that extensive
works have Teen established in Connecticut
for the manufacture OF thus new alley for
use in eiectrorp!ating and for similar pur-
poFes. The uae OF manganeacln its compounds

purpose. The cost OF its preparations, and \
want Of familiar knowledge Of its properties,
have prevented any attempts to Introduce it
