of the common Air at Sea. 375 
December 26. Being at.Cuvilli, a village four leagues 
from Roye, I examined the air of that place, and that 
which I had gathered on the road about twelve o’clock 
in the day-time-; I found them both at 1 03; the weather 
was frofty.

December 2 9. Being at Paris, I found the air in that 
capital at 103 ; the weather frofty. , x i ff

January 1 3.. The air of Paris was .98 ; it froze very

the fea, which have no marfhes in their neighbourhood.
