We have already published an explanation of the
process by which the new explosive is made, from
Professor OTro, who made the discovery simulta-
neously with ScH0NBErN, BoTTGER, and French
man-so that there are four claimants TO the merit
oft. But whether the process is the same in all
cases we cannot say SCH0NBEIN took out patents
for his discovery in several nations: but OTTo more
generously tells us all he knows on the subject.
Here is an extract from one of his reports, which
goes into details


h seems that no other acid than that procured by the
dlaton Of ten parts of satpee and parts of oil of vi
trio will confer upon cotton its explosive power Hy
dnate OF nitric acid dissoyes the


ton In good proper acid the cotton becomes transparent
and the fibre is not injured dissolved The acid by ds-
aon first procured is best Cotton dipped into il for half
mnue and then quickly pressed between glass plates
boards, and washed afterwards until it is entirely free from
acid, and subsequently dried produces superior exploding
article Using the acid secoad time, an inferior article is
made but if afe having been washed and dred it again
dipped into the acid, becomes excellent repetition Of
the manipulation necessarily augments the exploding quality


"Coon may even remain in the acid longer than half
minute That which has laid in II long twelve hours

any remains in it, salpee flavor will attach il when dry
and when exploding will leave any thing white acid

Common gunpowder, for which this discovery intended
to be substitute is composed Of rs parts Of ntre Is Of
charcoal, and 10 Of sulphur. The sulphur readily gnes
and fires the charcoal generating sufficient heat to convert
the solid nire into gas Of many thousand times its bulk
thus creating the explosive force which drives the bullet from
the gum The only of the sulphur TO convey the flame
with greater rapidy through the It does possess
the slightest explosive power
