MINUTES OF PROCEEDINGS OF 
the initial velocity 1270 f.s. is found corresponding to the distance 2033 
feet, to which adding the reduced range 738 feet, we get 2771 feet, 
and at this distance the velocity=1152*6 f.s., which is the velocity 
which the 4001b. shot would have at a distance of 1000 yards from 
the gun. Or, the loss of velocity of the 4001b. shot in 1000 yards = 1270 
— 1152-6 = 117*4 f.s. By the help of the Special Table 8, the loss of 
velocity is found to be= 1270 —1152 = 118 f.s. in a range of 1000 yards. 
In cases where great exactness is required the results given 
by the General Tables are to be preferred, because the coefficients 
have been changed for every change of 10 f.s. in the velocity, and 
the results have been given to one place of decimals. But it was 
deemed sufficient to change the coefficients for the Special Tables 
for every 50 f.s. in the velocity, and to neglect fractions of a foot in 
stating the velocities. 
Small Arms. —The following Tables for Small Arms are calcu¬ 
lated by the coefficients obtained from experiments with guns of 3 to 9 
inches in calibre. They are given with some little doubt, as the 
leap from a 3-inch to a ^inch bore is too great. Considering, how¬ 
ever, that the experiments made by Hutton with round balls of small 
diameter gave very fair results when applied to large shot, the fol¬ 
lowing tables may be of value until proper experiments are made :— 
Snider :—d —O’577 in.; w = 480 grs. = 0-06857 lb.; <2 2 -r-w = 4’855. 
Chassepot:—<2 = 0-44 in.; w = 380 grs. = 0-05428 lb.; d 2 -~w = S’566. 
Martini-Henry:—<2 = 0-45 in.; w = 480 grs. = 0-06857 lb.; d 2 -i-w = 2-953.
