it had (applied the Vacuum , when the Cock was again 
fhut, and the Globe, with the Water, put in the Scales, 
and then found to weigh 44 Pounds 9 Ounces which 
take from ,45 Pounds 7 Ounces, the whole Weight, 
as before, there remains but 14 Ounces, the Difference, 
which Iheweth that all the Air was nearly excluded out 
of the Globe by the Steam : In Ounces it (lands thus 
which is very near a perfect Vacuum,

with Steam as before, and both Cocks B B being 
clofed with the Globe full of Steam, we put the 
Globe in the Scales, and it weighed 12, Pounds 10 
Ounces I then opened one of the Cocks, and let 
in the Air, on which the Scale defeended ; and, by 
adding Weight in the other Scale, it was found to 
weigh 12 Pounds 11 Ounces; which lhewed that the 
Weight (not the Preffure) of the Air the Globe con- 
tained; was 7 an Ounce Avoirdupois.

and condenfed with cold Water on the Outfide of 
the Globe, and the Metal again made very dry, and 
the Air let into the Globe, the Water from the con- 
denfed Steam was found to weigh 4 Penny- weight.

now I continued the Globe longer with the Steam 
palling through it, by which it acquired a greater 
Degree of Heat ; for I found by thofc Experiments, 
that the lead Degree of Cold lefs than the Steam, 
a Part would be condenfed again into Water, by 
which the Quantity could not be certainly attained 
to, that would exclude the Air out of a certain Space, 
which is the chief End of this Experiment. But in 
this Experiment I fuccecdcd better ; for, on weighing
