from the clouds. The tadpoles feed on vegetable 

 substances or animalcules, thus differing from its parent 

 and future self, whose food is animal. The hind legs of 

 the frog are very much longer than the fore. 



THE GREEN FROG 



Is a large species, which is eaten in some parts of the 

 continent. 



THE BULL FROG, 



An inhabitant of many parts of North America, is not 

 less than eighteen inches from the nose to the end of the 

 hind feet. Its colour is a dusky olive, irregularly marked 

 with numerous brown spots, the under parts are altogether 

 paler, the hinder feet are very widely webbed. The bull

 they generally form a little basin before they flow into the 

 plains, and each of these basins are inhabited by a pair of 

 frogs who sit at the brink, and if disturbed, take refuge in 

 the mouth of the spring. The people of Virginia fancy 

 that they keep the springs clean, but they dislike them as 

 being sad devourers of their young ducks and goslings, 

 which they swallow whole. These frogs have a very loud 

 voice, in tone like that of a bull, and make themselves very 

 troublesome by their constantly exerting it ; they are 

 torpid during the winter; they are used as an article of 

 food, and have on their bodies nearly as much meat as is 

 found on a fowl. 



THE TREE FROG 



Is a very small species, which resides chiefly amongst the 

 trees. The extremity of each toe is furnished with a soft 

 fleshy knob, by which it adheres very strongly to the most 

 polished surfaces. Its belly, likewise, is covered with 

 glands possessing the same adhesive power. This little 

 animal often hangs suspended to the branches by its legs,
