4 Mifcellanea Curiofa. 



Upon this Suppofition, every 10 fquare Inches 

 of the Surface of the Water, yields in Vapour 

 per diem a Cube-inch of Water ; and each fquare 

 Foot half a Wine-pint ; every Space of 4 Foot 

 fquare, a Gallon, a Mile fquare, 69 14 Tons, a 

 fquare Degree fuppofe of 69 Englijh Miles, will 

 evaporate 33 Millions of Tons; And if the Me- 

 diterranean beefHmated at forty degrees long and 

 four broad, allowances being made for the Places 

 where it is broader, by thofe where it is narrower 

 (and I am ft re I guefs at the leaft) there will be 

 1 60 Square degrees of Sea , and confequently, 

 the whole Mediterranean mufl lofe in Vapour, 

 in a Summer's day, at lean: 5180 Millons of 

 Tons. And this Quantity of Vapour, tho' very 

 great, is as little as can be concluded from the 

 Experiment produced; And yet there remains 

 another Caufe, which cannot be reduced to Rule, 

 I mean the Winds, whereby the Surface of the 

 Water is licked up fbme times fader than it ex- 

 hales by the heat of the Sun ; as is well known to 

 thofe that have confidefd thole drying Winds 

 which blow fbm crimes. 



To efHraate the Quantity of Water, the Medi- 

 terranean Sea -receives from the Rivers that fall 

 into it, is a very hard Task, unlefs one had the 

 Opportunity to meafure their Chanels and Veloci- 

 ty; arid therefore we can only do it by allowing 

 more than enough ; that is, by affuming thefe 

 Riven greater than in all probability they be, 

 and then comparing rhe Quantity of Water void- 

 ded by the *I&4toes t with that of thofe Rivers, 

 whole Waters we deflre to compute. 



The Mediterranean receives thefe confidera-' 

 ble Rivers ; the Ibcrus, the Bj^one^ the Tiber-, 

 the Po y the Danube, the Neiftcr> the Boryftcne/,
