MINUTES OF PROCEEDINGS OE 
pamphlet is perhaps the most remarkable example which could be selected 
of that system of skilfully blending together things not necessarily connected, 
so as to produce an appearance which is wholly artificial, of keeping out of 
sight inconvenient facts and considerations, and of assigning undue prom¬ 
inence to others, which is characteristic, more or less, of the whole of the 
foreign remarks on these trials which we have read. It is also a good 
example of the insufficiency of the information out of which men may be 
tempted to construct a theory favourable to a particular view. We shall, 
therefore, proceed to examine the account of the Tegel trials as given by 
Captain von Doppelmair, supplying, as we proceed, such comments and 
omissions as may occur to us; rectifying such errors as we may observe; 
disentangling, as far as may be possible, the issues which Captain von 
Doppelmair has contrived to confuse; and, finally, observing how far the 
facts warrant the conclusions at which that officer has arrived. 
II. 
Comparative Penetrative Power of the Woolwich and Krupp Guns . 
Captain von Doppelmair commences his pamphlet with a description of 
the competing Krupp and Woolwich guns. We have already given the 
principal weights and dimensions of these weapons; but the more detailed 
information contained in Captain von Doppelmair^s pamphlet may be useful. 1

It will be observed that the maximum battering charge adopted for the 
Krupp guns at the outset was 46*30lbs. of Prussian powder; and it is 
important to notice this, because it will hereafter become necessary to 
observe how far this condition was departed from when the inability of the 
Krupp gun to hold its own became apparent. With this charge and a
