O common and well-known an animal requires 
no defcription ; but fome of its properties are 
fo fingular that we cannot pafs them unnoticed. 
Its {pring or power of taking large leapsis remark- 
ably great, and it is the beft fwimmer of all four- 
footed animals. Naturehath finely adapted its parts for 
thofe ends, the fore members of the body being very 
lightly made, the hind legs and thighs very long, 
and furnifhed with very ftrong mufcles, : 
While in a tadpole ftate it is entirely a water-ani- 
mal ; the work of generation is performed in that 
element, as may be feen in every pond during fpring; 
when the female remains opprefied by the male for 
a number of days. 
The work of propagation is extremely fingular, 
it being certain that the frog has not a penis intrans 5 
there appears a ftrong analogy in this cafe between
