Or by logarithms much shorter, thus: If the logarithm of 1.923, which
is .283979, be constantly added to the third part of the logarithm of
the weight, the sum will be the logarithm of the diameter. Suppose a
shot to weigh 24 pounds: add the given logarithm .283979 to the third
part of .460070 of the logarithm 1.3802112 of 24, the sum .7440494 will
be the logarithm of the diameter oi a shot weighing 24 pounds, which is
5.5468 inches.

If the weight should be expressed by a fraction, the rule is still
the same: for instance, the diameter of a 1¹⁄₂ pound ball, or ³⁄₂, is
found by adding the logarithm .2839793, found above, to .0586971 ¹⁄₃
of the logarithm of ²⁄₃, the sum .3426764 will be the logarithm of the
diameter required, _i. e._ 2.2013 inches.

As the diameter of the bore, or the calibre of the piece, is made ¹⁄₂₀
part larger than that of the shot, according to the present practice,
the following table is computed for this proportion.

DIAMETERS _of the shots and calibres of English guns_.
