5 I fi, 
WHen weCruifed in the Bay of Bifc*y t June the 
%tb t and had a hundred Fathom of Water, we 
took a Quart Glafs Bottle ftopt with a large Cork, and 
after tyed down with aftrong Packthread, as we ufe to 
for Bottle Syder, or Ale, fattening our Bottle to our 
Plumbing- rope, and with a Lead at the end, funk it to 
die bottom of the Sea, which as foon as we perceiv'd, 
we drew it up again, and found the Cork quite prefs'd 
thro* the neck of the Bottle into its cavity, and the Bot- 
tle full of Salt Sea- Water. We repeated our Experiment 
with another Bpttle~and Cork in the fame manner as be- 
fore, but the Cork being not found, the Sea- Water 
foak'd thro' it, and the Bottle was half full of Water, fo 
the Cork remain'd in the mouth of the Bottle not prefs'd 
down at all. We repeated our Experiment a third time 
in ninety Fathom of Water, with a very found Cork, 
and much larger than the mouth of the Bottle, for we 
were fore'd to beat it in with a Hammer as far as it 
would go, leaving about an inch of the Cork above the 
mouth of the Bottle, and tyed down as before, but it 
fucceeded not fo well as at firft, tho' the Cork was now 
prefs'd down into theneek, and became level with the 
mouth
