* Two of the fuzes were purposely made to rattle to compare with those of the service pattern reported 
m the preceding paragraph. 
Practice with time and percussion fuzes fired separately, in order to 
ascertain which fuze was in fault when a very large number of segment 
shells burst prematurely.

Thus E tittle and C. F. S. (Freeth’s) percussion fazes, whether fired separately or in Combination, are not 
to be depended upon. With regard to the F tilnefuze, as all the premature explosions occurred only when 
it was used in conjunction with C. F. S. (Freeth) percussion, the failures may be attributed to the com¬ 
bination. 
The practice with the special fuzes Was Very satisfactory, and contrasted favourably with those of the 
service, the only case of a premature occurring when the Elswick time fuzes were used in conjunction with 
the C.F.S. (Freeth) percussion. 
The action of the Boxer percussion fuze in the shrapnel shell was very quick, due, no doubt, to the whole 
effect of the explosion of the fuze being, on account of the solid head, directed down to the bursting charge. 
On account of the solid head, the fuze cannot be used in conjunction with a time fuze, and the delay and 
diificulty of fixing it, would be grave objections to its use. 
Summary of the segment , common, and shrapnel shells fired during 
the experiments.
