[1X4 The Natural Hij^ry Part lll^ 



fident within the Globe, b\}t is lubjeQ: 

 to Viciflitudes and Alrerations-* beiag 

 at certain Seafbns greater than at 

 others: being alfo greater in (bme Cli- 

 mates and Parts of the Earth than in 

 Others : it thence happens that the 

 quantity of Water at the Surface of the 

 Emh, though lent up from the Abyfe 

 with an almoft conftant Equality, is 

 ^ariom and^ uncertain^ as is the Heat 

 there ; at fomt Seafons^ and in fome 

 Countries^ the Surface ^^(?«W/>^, and 

 being even drowned with the plenty 

 of ic, the Springs fully and the Rivers 

 'high : at other Seafons , and in other 

 C<>untries both Springs an4 Rivers ex-- 

 ceeding low , yea ibmetimes totally 

 failing. 



That wh^n the Heat in the exteriour 

 Farts of the Earthy and in the ambient 

 Air, is as intenfe as that in the interi-- 

 cur Parts of it, all that Water which 

 paffes the Strata direBly^ mounting up 

 in feparate Parcels, or in form of Va-- 

 pour, does not flop at the Surface, be- 

 caufe the Heat there is equal both in 

 quantity and power to that underneath^ 

 which brought it out of the Abyfs. 

 '• This Heat therefore takes it here, and 

 ikm it up^ part of it immediately out-
