it, which can be used for indirect laying. The sight has a rack cut 
on it and it is run up or down by means of a pinion ; this can, how¬ 
ever, be put out of gear if it is desired to make a considerable alteration 
in the elevation rapidly. The sight bar is a curved one.* 
Hitherto “ sight plates ” have been used with German field guns ; 
they could be fitted on to the bar of the Tangent sight, as required, so 
as to make the reading on the sight bar appear to be the same as the 
reading found necessary for the fuze (the fuzes are graduated in 
metres); thus one order was sufficient for range and fuze. These 
plates are now done away with and a moveable sleeve or socket is 
provided to perform the same functions. 
The Richtflache is retained; this is an apparatus which fibs on the 
breech of the gun and is used for obtaining the line in indirect laying. 
It fits on to the small pins which can be seen sticking up from the 
breech of the gun (see Fig. 1). 
Ammunition .—The charge is contained in a brass cartridge case; 
the projectile is not fixed to this case. Two natures of projectile are 
used, viz., shrapnel shell and high explosive shell; they are both four 
calibres long and have one driving band only. They are of the same 
weight, 15 lbs. The shrapnel contains 300 bullets which weigh 45 to 
the pound; it has a base burster of black powder and the bullets are 
Screw plug. 
* A description, with drawings, of a sight, which seems to be very similar to the German one, 
and which was invented by Capt. Korrodi, of the Swiss Artillery and Secretary of the Swiss 
Experimental Committee is given in Bivista di Artiglieria e Genio, December, 180S, «nd in Revue 
d* Artillerie , February, 1899.
