4. The destroying influence ( EinwirJcung ) of the new material on the 
barrel of bronze and other guns is entirely obviated ( aufgehoben) by the new 
material, according to the official trials of 1860 .—“ As a proof of the above 
I quote the fact, that after more than 2000—say two thousand rounds fired 
from a bronze 4-pr. in the shortest possible interval, the gun has not suffered 
any damage whatever of its first effective qualities (LeistungsftihigJceit). The 
new material may also be employed with cast-iron breech-loading guns, &c. 
with the same success.” 
5. The method of producing the new material combines all the conditions 
which lead us (the commissioners) to the conclusion, that the production of 
the preparative of a constant effect [gleichmdssig wirkend), and also its 
invariableness, are bound within rather wide limits. The necessary apparatus 
for the manufacture of this new material is simple and not expensive, faci¬ 
litates and accelerates the manipulation, which moreover is of a far less 
dangerous character than the manufacture of gunpowder. "During the 
summer of 1861 there have been produced about 50 tons of this new 
material without having been attended by the slightest accident.” 
6. The manufacture of all kind of cartridges for guns and for mines is 
very simple (sehr einfach ), easily and rapidly to be effected ( leicht und rasch 
bewirken), on account of the exclusive employment of machines, whilst it is 
well known that with the manufacture of gunpowder cartridges, hand labour 
is predominant. 
7. The conveyance of this material to the most distant parts of the 
empire—with railway and common carriage—under intentionally difficult 
circumstances, has always been effected without delay or trouble whatever 
8. This new material after burning, leaves only an extraordinary small 
quantity of deposit [nur dusserst geringe Ruclcstdnde) . The barrel of a gun, 
after many rounds is scarcely blackened ( nach vielen schussen Jcaum 
geschwarzt ), and the disagreeable smoke attending the explosion of a gun¬ 
powder cartridge is done away altogether (ftittt ganzweg.) 
9. The new explosive material submerged under water six to eight weeks 
showed no alteration whatever of its previous effective qualities ( Iceinerlei 
Verdnderungen ihrer ursprunglichen WirJcungsfdhiglceit) after being dried by 
means of machines in a few minutes. 
10. The effect of recoil (Riichtoss) is by employment of this new 
material far less {hedeutend geringer ) than by the employment of powder 
cartridges. 
11. If we consider the quantities of gunpowder and this material to 
produce the same effect, there is then at present no difference of note 
between the cost of both preparations; if however the manufacture of this
