Anatyfis of the Air. 237 
of the whole, nearly what was abforbed 
by a Candle in the fame veflei, in Expert 
ment 106. 
I placed at the fame time, in the fame 
manner, another almoft half grown Rat 
tinder a veflei, whofe capacity above the 
furface of the water zz> (Fig. 35-) was but 
594 cubick inches, in which it lived 10 
hours 5 the quantity of elaftick air which 
was abforbed, was equal to 45 cubick 
inches, viz. tV part of the whole air, 
which the Rat breathed in : A Cat of three 
months old lived an hour in the fame re- 
ceiver, and abforbed 16 cubick inches of air, 
viz. 7- part of the whole 5 an allowance 
being made in this eftimate for the bulk of 
the Cat's body. A candle in the fame veflei 
continued burning but one minute, and ab- 
forbed 54 cubick inches, *rr part of the 
whole air. 
And as in the cafe of burning Brimfione 
and Candles , more air was found to be ab- 
forbed in large veffels than in fmall ones ; 
and vice verfa , more air in proportion to 
the capacity of the veflei was abforbed in 
fmall than in large veffels, fo the fame holds 
true here too in the cafe of gnimals.
