ACDE reprefents a tin pan, filled with Rathbone- 
p’ace water as high as BG. HKL is another tin pan, 
within the ffrfi, in the manner of an inverted funnel, 
and made in fuch a manner as to leave as little room as 
poffible between that and the fides of the outward 
veffel. M reprefents a bottle, full of the fame water, 
inverted over the mouth of the funnel. By this means, 
as faff as the air is difengaged by heat from the water 
within the funnel, it muff neceffarily rife up into the 
bottle. The Rathbone-place water, put into the 
veffel, weighed 41 1 ounces, the funnel held 353 
ounces. A bottle full of water being inverted over 
the mouth of the funnel, as in the figure, the water 
was heated, and kept boiling about 4 of an hour. As 
foon as one bottle was filled with air, it was removed 
by putting a fmall ladle under its mouth, while under 
water, and fet with its mouth immerfed in the fame 
manner in another veffel of water, taking care not to 
fuffer any communication between the included air 
and the outward air during the removal. At the fame 
time, another bottle full of water was inverted over 
the mouth of the funnel,, in the fame manner as the 
former. It was not eafy tel.ling how much air was 
discharged from the water j as the air in the bottles, 
when firff removed, was hot and expanded ; and, before 
1 could be fure it was cold, there was fome of it 
abforbed by the water : but there feemed to be above 
75 ounce meafures difcharged, fcarce twenty of 
which arofe before the water began to boil. The 
water continued difcharging air after the experiment 
was discontinued. In about a day’s time, much the 
greateft part of the air was abforbed, fcarce fixteen 
u nee meafures remaining. That which was abforbed 
appeared to be fixed air, as the water which bad
