138 An ESSAY concernwg the Chap. 4, 



a Foot Cubical of Water weighs 76 lb. which 

 Foot containing 1728 Cubick Inches, and 

 divided in the 76 lb. gives ^ an Ounce and 

 13 ~ Grains, which is the weight of an Inch 

 Cubick in Water : The Weight therefore of 

 the 235 Grains is vfr, or 3 5 Parts of a Cu- 

 bick Inch divided by 38. The Area then of 

 a Circle whofe Diameter is 7 Inches and up- 

 wards, is above 49 Square Inches 5 by which 

 if you divide the Quantity of Water carry 'd 

 off in Vapours -!-g- Parts of an Inch, the Pro- 

 duft is -rr^-r, or tt : From whence it appears 

 that there was 53 Parts of an Inch wafted 

 in that Experiment. A plain Proof how 

 great a Quantity may be carried off in great- 

 er Dimenfions of Water, even enough to fup- 

 ply all Rains, Dews, &c. 

 the Dijfu- But when one comes to fpeak of the Dif- 

 f ;^fj;^^fufive Power of the Sun, befides^ the Light 

 ' it conveys to thefe Sublunary Regions, (with- 

 out which Mankind would grovel and wan- 

 der in the Dark, and all the Joy and Pleafure 

 of this Life be dull and difmal) how does 

 it by its Genial and Chearful Rays exhila- 

 rate the Vegetable part of the Creation, and 

 make Nature itfelf to fmiie ! 



It influences deep Grounds, by warming 

 and chearing the Pores of the Earth, when 

 diiated and fodden by too much Wet 5 and 

 gladdens it, putting the emulgent Fibre on 

 feeking its Food : The Surface it helps, by 

 difpeliing or attrafting the Vapours that 

 would otherwife make it noxious, darts its 



Beams
