Experiments have shown that gunpowder COULD
be exploded by the stroke of iron upon iron; iron
upon copper; copper upon copper; iron upon marble
and by using the balistc pendulum, by lead upon
lead and with suitable precautions even by lead
upon acood. The experiments most clearly show,
that, in all the manipulatons Of powder manufac-
tory, all violent shocks and percussions should be-
carefully avoided, since they may occasion the dis
engagement of sufficient heat to produce ths nfan-
nation of powder.
