English ordnance as were achieved for the Krupp ordnance in the emergency 
of Tegel; and the convenient assumption of the Prussian authorities and 
foreign critics that the English gun was unable to realise such benefit, 
is therefore completely disproved. And, as the Woolwich guns exhibited 
an equality in actual penetrative effect when confessedly from 18 to 30 
per cent, inferior in theoretical ballistic power, 1 now that they are brought 
up to the Krupp guns in ballistic power, without any other change than 
that of using a suitable powder, it is clear—from the very theories, 
arguments, and tables admitted on both sides—that the English system, as it 
now stands, must be actually at least 18 to 30 per cent, superior to the 
Prussian system as it stands. 
We append a table which shows the relative powers of the two systems, 
with the descriptions and charges of powder now officially approved.
