The author here quoted, has propofed to change
the fabric of all the piem employed in the Britifh navy,
from the tIVenty four pouodm dOIVolVards, fo that
they may have the fame or lefs weight, but a larger
bore. He thioks Ihe thirty·two pouoders io prefeot ufe
would be proper models for Ihis purpo(e. Thefe be·
iog of fifly.tlVO or fifty·three hundred weight, have
fomewhat lefs than a hundred and IWOthirds for each
pound of bullet. Aod that this
pr~portioo
would ao·
fwer in fmaller pieces, in point of llrenglh, feems elear
from thefe conftderations:
l .
That the Ihenglh of iroo
or any other metal, is in proportion to its fubllaoce.
2 .
That Ihe lefi'er quantilY of powder filed io a fpace
it fills, has proportionably lefs force thao a Iarger quao·
tity; fo tha! if
t\Vo
pieces, a large and a (mall ooe, be
made in Ihe fame proportion to their refpeélive bullets,
and 6red witb a proportiooalíle qUántity of powder, the
Iarger piece will be more llraioed, will heat more, and
recoil more than the fmaller.
On this fcheme our prefe"t twenty.four pounders
will be eafed of fix or eight hundred weight of ufeleCs
metal; and fome pieces of a lefs caliber. as nine aod
fix pounders, would be fometimes eafed by fourteen
huodred: hence much larger guns of the fame weight
might be boroe. Thus, inllead of ftx, nine, twelve,
aod eighteen pounders, our fhips l1light carry twelve,
cighteen, and twenty.fuur pounders : guns would be
kept cooler and quieter, and would be of more fervice,
in many refpeBs, if their ufual charge of powder were
diminifhed.
