quantities as the water with filk had done in the former expe- 
riments, and nearly of the fame quality. 1 1 cubic inches of 
this air, furnifhed the eighth day from the beginning of the 
experiment, or the third of funfhine, proved with nitrous air 
gave 10 + 372—1,24., or 266 degrees of purity. 
The water was faintly tinged of a greenifh, yellowifh call, 
and the Eider down, when examined attentively, appeared to 
be covered with a greenifh dime. 
Experiment N° 8.

The globe N° 3. with the hare’s fur (which was white) fur- 
nifhed more air than the fheep’s wool, but not fo much as the 
Eider down. After four days of funfhine, 1 collected 2 cubic 
inches of this air, which, proved with nitrous air, gave 
ia + 3?2— 1,44, or 256. 
The water had acquired a very faint yellowifh hue ; but it 
did not appear to have loft much of its tranfparency, or to be 
dilpofed to depofit any fediment. 
The air produced in this experiment made its appearance in a 
different manner from that furnifhed in thofe preceding it, the 
air -bubbles which appeared upon the furface of the fur being 
at confiderable diftances from eacli other, and growing to an 
uncommon iize before they detached themfelves to rife to the 
furface of the water. 
Experiment N° 9. 
The globe N° 4. with cotton wool furnifhed a confiderable 
quantity of air which appeared to be better than that furnifhed 
by any of the five other globes. Proved with nitrous air, it 
turned out ia + 30=11,0-], or 293 ; and, what was particular, 
the water did not appear to have altered its colour in the leaft, 
or to have loft any thing of its tranfparency.
