mittee,* charged to examine into the improvement of bronze for field 
guns, the report of which committee has just been published, and will 
be found full of most useful information as to the nature of bronze 
guns, and the causes of local defects. It is accompanied by various 
tables of chemical analyses of bronze, and details as to the different 
alloys, fracture, &c. Appended to the Report will also be found a 
precis of the lecture by General Yon Uchatius, and a translation of a 
critique upon the lecture taken from the “ Militarische Blatter,” which 
is treated of in the following Note II. 
NOTE II. 
In the preceding pages no attempt has been made to criticize the 
theoretical opinions expressed by General Yon Uchatius, but as in his 
lectures he distinctly challenged comparison between a bronze-steel 
gun and a gun of Krupp steel, we may now examine what has been 
said on the other side against bronze steel theoretically, as a material 
for Ordnance. There hardly appears a doubt but that steel might be 
so improved as to be superior to bronze steel in every required quality 
under somewhat similar treatment. The practical point just at 
present, however, which Austria requires to know is, whether bronze 
steel can furnish her with a thoroughly efficient Field Ordnance, 
supplied from her own Arsenals, seeing that her capabilities of steel 
manufacture are not as yet sufficient to allow of her using that material 
without having recourse to other countries. 
For ourselves this comparison has much scientific, though perhaps 
little practical interest, so we will take in succession the points of com¬ 
parison between a steel bronze gun and a Krupp gun, as laid down by 
General Yon Uchatius with his critics* remarks thereupon. 
To avoid any misunderstanding as to technical terms, it will be 
advisable to state their meaning distinctly, and the following graphical 
illustration of the “limits of elasticity** and “fracture** of a metal 
extracted from the “ Militarische Blatter will aid us in this very 
much:—
