NOEDENFELT AND HOTCHKISS GUNS. 
purposes, while Germany, as will be seen from the following extract 
from the Militar- Wochenblatl, 22nd January, 1881, has followed their 
example:— 
“ An imperial order dated 11th January, 1881, has prescribed the 
introduction of the Hotchkiss revolving gun into the German navy. 
All ships of war will carry a sufficient number of these guns, so that 
every point within a range of 200 yds. may be simultaneously swept by 
the fire of at least two of them.” 
AUSTRIA.—TEIAL OF A REPEATING RIFLE. 
On the 4th January, 1881, trial was made at Vienna of the Falmisberg 
repeating rifle. The repeating arrangement, which is very simple, can 
be easily adapted to the Gras rifle in use in the service; it was found 
to act perfectly, and eight shots were fired in five seconds. Further 
trials will take place. 
Use of Dynamoge .—By order of the War Minister, trials have been 
made at the arsenal of a detonating composition invented by Mr. 
F. J. Petry, a civil engineer, and called by him Dynamoge, with the 
following results: Initial velocity with dynamoge 323*9 metres to 
356*3 metres, against 295*6 metres to 302*2 metres with gunpowder. 
The firing with the latter was more accurate, but this was partly 
attributed to want of confidence in the men using the new composition. 
In both cases the bulk of the cartridge is the same. 50 rounds were 
fired with great rapidity, when it was found that while the barrel of 
the rifle fired with gunpowder was so hot that it could no longer be 
nsed for a time, that fired with dynamoge was but little heated. The 
former rifle was very foul after the trial, while the dynamoge left so 
little residue that a piece of rag once passed through the barrel was 
sufficient to clean it. There was but little flash and smoke from its 
discharge.
