"At the extremity of the Red Sea is that famous neck of land called the Isthmus of Suez, which forms a barrier to the Red Sea, and prevents its communication with the Mediterranean. In a preceding article we noticed the reasons which inclined us to think that the Red Sea is higher than the Mediterranean, and that if the Isthmus of Suez was cut, an inundation and an augmentation of the latter might ensue. To which we shall subjoin, that if even it should not be agreed that the Red Sea is higher than the Mediterranean, it cannot be denied that there is neither flux nor reflux in the Mediterranean, adjoining to the mouths of the Nile; and that, on the contrary, in the Red Sea the tides are very considerable, and raise the water several feet, which circumstance alone would suffice to send a quantity of water into the Mediterranean if the Isthmus was broken."
"The ocean, therefore, surrounds the whole earth without any interruption, and the tour of the globe may be made from the south point of America; but it is not yet known whether the ocean surrounds the northern part of the globe in the like manner; and all mariners who have attempted to go from Europe to China by the north-east of north-west have alike miscarried in their enterprises."
"The water of the Black Sea appears to be less clear and less saline than that of the ocean. There are no islands in it, and its tempests are more violent and more dangerous than in the ocean, because the whole body of its waters being contained in a bason, which has but a small outlet, when they are agitated, they have a kind of whirling motion which strikes the vessels on every side with an insupportable violence."
"The lakes any ways remarkable are the Dead Sea, the waters of which contain much more bitumen than salt: it is called the Bitumen of Judea, but is no other than the Asphaltes, which has caused some authors to call it the Asphaltic Lake. The lands which border this lake contain a great quantity of this bitumen; and many have supposed, as the poets feign of lake Avernus, that no fish could live therein, and birds which attempted to fly over it were suffocated; but neither of these lakes produce such mortal events; fish live in both, birds pass over them, and men bathe therein without the least danger."
