the Barrels, all the Air that was included in the upper 
Parts of them was blown with great force into the Bell, 
whilft the Water entred at the Bung-holes below, and 
fill’d them .* and fofoon as the Air of the one Barrel had 
been thus received; upon a fignal given, That was 
drawn up, and at the fame time the Other defcen.ied : and 
by an alternate Succeflion furnifhed Air fo quick, and in 
fo great Plenty, that I my felf have been Ore of live 
who have been together at the Bottom, in nine or ten 
Fathoms Water, for above an Hour and haT at a time, 
Without any fort of ill cOnfequence : and i might have 
edntinued there as long as I pleafed, for any thing that ap- 
peared to the contrary. Befides the whole Cavity of the 
Bell was kept entirely free from Water, fo that ( far on a 
Bench, which was diametrically placed near the Bottom, 
wholly dreft with all my Cloaths on l only oblerved, 
that it was neceffary to be let down gradually at firft, as 
about iz Foot at a time ; and then to flop and drive out 
the Water that entred, by receiving thre or four Barrels 
of frefh Air, before 1 defceoded further. But being ar- 
rived at the Depth defigned, l then let out as much of the 
hot Air that had been Breathed, as each Barrel would re- 
plenifh with Cool, by means of the Cock at the Top of 
the Bell 5 through whole Aperture, though very (mail, 
the Air would rufh with fo much violence, as to make the 
Surface of the Sec boyle, and to cover it With a white 
Foam, notwithftanding the great weight of Water over us. 
Thus I found I could do any thing that was required to 
be done juft under us ; and that, by taking off the irage, 
I could, for a fpace as wide as the Circuit of ~he Bell, lay 
the Bottom of the Sea fo far Dry, as not to be over-fhoes 
thereon. And by the Glafs Window, fo much Ljght 
was tranfmitted, that, when the Sea was clear, and es- 
pecially when the Sun fhone, I could fee perfe&ly well to 
Write or Read, much more to fallen or lay hold on any 
\ thing
