Taking these experiments in detail, it appears that,— 
1. At a single line of targets, with boggy ground in front, the segment shell with time and percussion fuzes 
gave a larger number of hits per effective round than the shrapnel with the wood time fuze, but less with 
the percussion fuze only, as might have been expected on account of the nature of the ground. 
2. At targets in double rows, 6 feet apart, the segment shell, with time and percussion fuzes, gave a less 
number of hits per effective round than the shrapnel with the wood time fuze. But with the segment, using 
the percussion fuze only, the results were slightly in favor of the segment. 
At targets in double rows, 20 to 30 feet apart, the segment shell, with percussion fuze, was far superior to 
to the shrapnel, either with the wood time or the special concussion fuze. 
3. At 6 feet targets, representing columns, the segment shell, with time and percussion fuze, produced on 
the whole, a more destructive effect than the shrapnel shell with the wood time fuze : the superiority of the 
segment, with percussion fuze only, was still more marked. 
In the experiment in which special percussion fuzes were used for both shrapnel and segment shell, the 
segment again showed a great superiority. 
4. At skirmishers without supports either in the open or in broken ground, the segment shell with time and 
percussion fuzes had slightly the advantage of the shrapnel; but at skirmishers with supports and reserves, 
the shrapnel was more effective.
