Frog and Tadpoles 



The Frogs, in the early stage of existence, are called Tadpoles. At first they appear to consist solely 

 of hear 1 , and tail, but, ere long, four legs are developed, the tail drops oil', and the young Tadpole becomes 

 a complete Frog. Another change is, though, in its Tadpole state, it was wholly a water animal, on becoming 

 a Frog, it must often come to the surface to breathe. Frogs hybernate at the bottoms of ponds and marshes. 

 Their shun has the property of absorbing water, so that an emaciated frog, put in a damp place, will soon 

 look plump. There are three principal species, the CommonFrog, Ihdl Frog, and Tree Frogs. 



The Common Frog frequents marshy spots and river-banks, and is a capftal swimmer. The Bull Frog 

 is very voracious, and feeds on fishes, shell fish, and even young lewis. Its leaping powers are wonderful. 

 The Tree Frogs are singular creatures, the construction of their feet enabling them to traverse tree-branches 

 and even t',- hang on the under side of a leaf, which they so resemble in color, that insects coming unwarily 

 nigh, are seized by the vigilant animals.

The Toad has 

 been the theme of 

 many marvellous 

 tales, among which 

 are its being pois- 

 onous, and having 

 ;; precious jewel in 

 its head. It dee.-, 

 in fact, secrete from 

 its skin an acrid 

 humor, which do- 

 le-ids it- against 

 certain animals, but 

 otherwise these ac- 

 counts are purely 

 fabulous. It is ea- 

 sily tamed. The 

 Toad occasionally 

 casts his skin, but 

 always swallows it.
