that single drop placed on the tip Of the
tongue will cause violent headache, which
will last for several hours. The liquid
seems to have been almos. forgotten by
chemists. and it is only now that M. Nable,
Swedish engineer, has succeeded in ap-
plying i to very important branch of his
art-namely. blasting. From paper ad-
dressed by him to the Academy OF Scien-
ces, we learn that The chief advantage which
this substance, composed of one part of
glyccrine and three parts of nitric acid,
possesses, is, that il requires a much small
er hole or chamber than gunpowder does.
the strength of the latter being scarcely
one. tenth of the former. Hence, the mi
ner's work. which. according to the hard
ness oi the rock, represents five to twenty
times the power Of the gunpowder used, is
so short that the cost OF blasting is often
reduced by fifty per cent. The process is
very easy. If the chamber OF the mine pre-
sent, fisures, il must be lined with clay to
make i; water-tight; this being done, the
nitro.g glycerne is poured in, the water af-
ter Il, which. being the lighter liquid, re-
mained al the top. A slow match with a
well charged percussion cap at one end is
then introduced into the nitro -glycerine.
The nine may then be sprung by lighting
the match, there being no need Of tamping.
0n The 7,h of June las. three experiments
we're made with The new compound in the
open part of the tin mines of Altenburg, in
Saxony. In one oil these chamber thirty
four miIlime,res in diameter was made per.
pendlculariy in dolomitic r0ck, sixty feet
in length, and at distance of fourteen feet
IRON rs extremity. which was vertical. AT
a depth Of eight feet vault filled with clay
Was found. in Consequence of which the
bottom Of the hole was tamped. having z
depth Of seven feet. 0ne iitre and halt
Of nitro glycerine was then poured in; il
occupied five feet; match and stopper
were then applied, as stated, and the mine
sprung. The effect was so enormous as to
fs>ure fIty feet in length, and another
twenty feei."
/ "oHEaIcAL NATURE OF THE COMPOUND"
"The Blasting Oil, or Nitro glycerine
Of Mr. Nobel, is chemical compound oi
six equivalents of carbon, five equivalents Is
ot hydrogen, three equivalents of oxygen,
aud three OF nitrogen.
Practicslly, il is composition Of rs
per cent. OF nitric acid and IS per cent. oi
gl,cerine oil.
A scientific calculation II 'he volume
oi gasses, developed by the combustion oil
lhis compound and the combustion OF good
ganpowder. proves that niiro.g glycerine,
compared with gunpowdcr, possesses thir-
teen times It's p0wer. when volumes are
compared. and eight times IL power for
equal weight. Therefore, where eight
pounds OF gunpowder are wanted, one pound
oi nl,ro-gl glycetIne will be sufficient 10 pro-
duce the same effect"
