Ëgyptian Bat is tail)efs, and much refemble^ 

 that of Madagafcar, but much lefs. As a duck 

 is a web-footed bird^ a Bat is juft in the fame 

 fenfe a web-footed beaft or quadrupède, though 

 they differ in many refpe(5ls : a duck, or other 

 water-fowl, hath the toes webbed together with 

 a flrong, tough, though pliable web, of a fmall 

 dimenfion, yet large enough to work in fo denfe 

 a medium as water : the Bat hath the legs for- 

 Ivards webbed principally, though thefe webs are 

 ialways joined to the hinder legs -, the webs are 

 exceeding thin, foft and pliable, and vaftly ex- 

 tended in breadth, if compared with the webs 

 on the fe&t of fowls ; the reafon of which is ma^ 

 nifell ; for the air being a medium vaftly more 

 rare than that of water, it requires a membrane 

 broader, thinner, and more light and delicate 

 to work and fupport itfelf therein. It is conve- 

 nient for water-birds to have their oars in the 

 hinder-parts of their' bodies, bdcaufe the water 

 is under them, and they row themfelves forwards 

 on its furface ; but it is different in Bats ; for 

 they have their webs principally on their for- 

 ward limbs, in order to row themfelves forwards 

 in the air. A gentleman, an eye-witnefs, has
