inflammation they meafured 4* ; lime water contracted them 
to 2|. 
In this experiment 2 1 meafures of fixed air were formed, 
which is nearly 0,28 lefs than the inflammable air ufed in this 
experiment is capable of producing. We have therefore only 
0,28 to account for the expanfion ; and we cannot fay, that 
the whole of this was decompofed, as the dephlogifticated air, 
even in this experiment, was not quite fufficient to faturate 
the two kinds of inflammable air ; and therefore a fmall quan- 
tity of heavy inflammable air might remain in the rcfidue in 
its original ftate. 
Exp. 6. A quantity of heavy inflammable air, which mea- 
fured between 3! and 3!, was expanded by about 3C0 tleftrical 
fhocks to 6 \ full meafure. To thefe were added 5J ot de- 
phlogifticated air. After inflammation they mealured 4*, and 
were reduced by lime water to 1^. 
The inflammable air in this experiment was between 35 and 
31 ; we will therefore take 3,29, the arithmetical mean of thofe 
numbers. The quantity of fixed air produced is lefs by 0,36 
than could be produced from the fame airs without electrifying. 
It is probable, that a fmall quantity of the heavy inflam- 
mable air may efcape unaltered in each of thele experiments ; 
the following were therefore made with a ftill greater propor- 
tion of dephlogifticated air, and the refidues were examined 
with more attention. 
All the preceding experiments were made with the fame 
airs ; thefe being exhaufted, a frefh fupply was procured for 
thofe which follow. The purity of this dephlogifticated air 
was fuch, that one meafure of it being mixed with 1 1 ot ni- 
trous air was reduced to 0,2 of a meafure. The inflammable 
air was lefs pure than the former. In the two following 
experiments
