1between two round Boards of ſomewhat a greater Diameter than
the Globe, with four pillars, as in the enſuing figure doth graphically
appear. But in the round Board which is put over the hole or mouth
of the ſaid Globe, you muſt alſo make a round hole ſomewhat
rower than that of the Globe, but yet big enough for a man to paſſe
in and out thereat. Afterwards under this round Board ſo bored,
you muſt place and fix another round bored piece of Lead of ſuch
thickneſſe, as that it may be able to draw the ſaid Ball or Globe of
Glaſſe, together with the Diver in ſuch manner under Water, that
the upper round Board do reſt in the Surface of the Water, namely,
that it may not be ſo heavy as to ſink the Globe and Diver to the
bottome, but only to retain it beneath the Surface of the Water,
which by tryal may be eaſily proportioned, namely, by adding or
taking away Lead from the Baſe, according as occaſion ſhall require.
Next you are to frame a ſeat for the Diver to ſit commodiouſly in
the ſaid Ball or Globe, and next faſten a Ball of Lead to the end of
a Rope, as many fathom long as the water is deep into which you
would deſcend, and ſomewhat more, as was ſaid in the preceding
Explanation. And that Ball of Lead ſhould be of ſuch bigneſſe, that
applied to the ſaid Model, it may be ſufficient to make it deſcend to
the bottome leiſurely, or ſwiftly, as he ſeeth cauſe who is to dive.
And make an handle or peg in the ſaid Globe whereat to faſten or
belay the other end of
the ſaid Rope, and to
draw it eaſily upwards,
330[Figure 330]
or let it looſe at the
pleaſure of him that is
within, and this may be
eaſily done by joyning
and faſtening four
pieces of wood upright
in the mouth or hole of
that bored Board and
Lead, which ſhall be
about the mouth of the
ſaid Globe; and that
I may be the better
underſtood, I will give
it you in figure with the
Diver ſitting therein.
If you would deſcend to the bottome of ſome deep water by help
of this Machine, you are to proceed according to the directions
ven in the precedent Explanation.
