evident from the Fads and Reafonings contained

falls in Rain, Snow, and Hail, is very different 
in different Parts of Great Britain ; there com-

Lemma II. The Quantity of Rain which falls in 
Lancashire, during the four hottefl Months of the 
Year, viz. May , June , ^July, and Auguft , doth 
not at a Medium amount to more than a third 
Part of the Quantity of Water, which falls in 
Rain, Snows, and Hail, during the whole Year. 
Lemma III. The Water which afeends in Vapours 
from the Sea very greatly exceeds that which de- 
scends thereon in Rain and other aqueous Meteors : 
But the Quantity of Water, which ufually exhales 
from a given Part of the Ocean in a given Time,

Lemma IV. The Quantity of Water which com- 
monly exhales in Great Britain from fhallow 
Ponds during the four hotteft Months of the 
Year, greatly exceeds the Quantity of Rain which 
commonly falls on the Surface of thofc Ponds 
during the faid Months.
