As one cubic foot, or 1728 cubic inches,
Is to the content of the body,
So is the tabular specific gravity
To the weight of the body.
_GRAPE SHOT._—See the word _Shot_.
_GRANADES._—Hand granades may be thrown to the distance of 13 fathoms.
For their dimensions, see the word _Shell_.
_GUNNERY._—By the assistance of good tables of practice, and the tables
of amplitudes, sines, tangents, and secants, all the cases in gunnery
in a nonresisting medium may be easily solved; and perhaps the solution
may be sufficiently correct for practice, if the initial velocity
of the projectile be not so great as to make the air’s resistance
considerable.
For the tables of ranges with ordnance, see the different natures, as
_Gun_, _Mortar_, &c. and for the tables of amplitudes, sines, tangents,
and secants, see pages 151 and 152.
