* The striking velocity equiva’ent to that produced by a charge of 25 lbs. at a range of 1200 yds. 
f The difference between the initial velocity of the steel and chilled shot is due to the greater weight and smaller 
diameter of the latter. 
100-pr. S. B. Gun of 125 cwt. 
Birth’s Steel.— Two shot of Birth’s steel were fired, one round with a full charge 
of 25 lbs., and one round with a reduced charge of 9*75 lbs., or the equivalent of the 
striking velocity due to a range of 1200 yds. when the full charge is used. The shot 
did not penetrate, although the skin was injured in the former case, and only made but 
a slight indent, 1*7" in the latter. 
Brown’s Steel.— Two shot of Brown’s steel were fired, both of them with the
