Dualin--A New Explosive.
I'VE .re in receipt Of impurities con
cerAing this new explosive. concerning
which We can only co4municaie euch
fac,s as the inventor, Leqt. Carl Dit
mar, OF the Prassian amy, chooses to
make Known. We hive not yet ex-
aminsa any of this substance. nor have
We seen any accountspf its ingredients
or mauafacture. Lieut.. Dittmar, as We
learn from q neat circular, has estab
lished himself in Bos,Dn, as manufac-
tsrer Of duelin, xyloglodine, and other
explosive mixtures" and is ready to
deliver the, new material at prices
ranging from eighty cents to one dol
lar and fifty cents per pound. according
to strength. No. 4, which seems to
be strong enough for most uses, Is one
dollar and ten cents per pound.
According to this pamphlet. dualin
was FIRST introduced into Germany in
April last. In many mining districts,
especially in most mines belonging 10
the Prassian Government, it is now
used instead of common powder, and
ltas.evcn taken the place Of nitroglyce-
riie aud dynamit-giabt powder. VI
It's general properties. It is only tolc us
that dualin il a powder. l: is fabri-
Gated six different degrees of strength
the use of which will depend on the
degree of hardness AID toughness OF
the material intended to I've subjected
to the action of the powder. If lighted
in the open air. i will burn without
exploding; but if confined, it may be
made to explode IL the same way as
common powder. 1t ia not sensitive to
concussion; will rot decompose itself,
nor cake or pack together. and may
be readily filled. into cartridges or
blast holes. requiring no other than
watertamping. 1t matters not whether
the place where it is stored be warm
or cold, dry or damp. II has from
four to fifteen times the strength OF
common powder, aud is, therefore,
stronger than nitro-glycerine or dyna-
nit.
Among tue advantages claimed fol-
dua.in over other explosive agents, is
tia fact that II may be stored, trans
ported, manipulated and applied with
less risk that common powder. 1t may

cartridges, ready for use. the only oh.
