SMOOTH-BORED GUNS, AND ON SEVERAL VARIETIES OF PERCUSSION FUZE. 
Brigadier-General J. Sr George, C.B., R.A., President . 
Captain L. G. Heath, C.B., R.N., Vice-President . 
Colonel Hogge, C.B., R.A.

1. The following detachment was detailed for this duty by Colonel Burke 
Cuppage, R.A., commanding the district., and arrived at Newhaven, August 
7th, 1863:— 
6 officers and 1 assistant-surgeon. | 86 rank and file. 
6 serjeants. ' J 3 trumpeters. 
2. The original object of the experiments on which the Committee have 
now the honour to submit a report, was to determine whether the Armstrong 
pillar fuze is sufficiently sensitive to explode shells on striking earthwork, 
and to try a more sensitive form of it. Since the period when this question 
was first raised (December 1861), several other forms of fuze have been 
proposed, and the Newhaven experiments embraced the trial of the following 
varieties:— 
i 
(1) The service pillar fuze for rifled shells only. 
(2) A more sensitive pillar fuze. 
(3) The field service C percussion fuze, enlarged to Moorsom gauge, 
and made to screw into the shell. 
(4) Pettmaffs L. S. fuze for spherical shells. 
(5) PettmanV S, S. fuze, adapted for rifled shells.
