FROGS, TOADS, AND REPTILES. 255

I used to open the gate in the railings round the pond, and 

 call out ' Tommy ' (the name I had given it), and the frog 

 would jump out from the bushes, dive into the water, and swim

The following observation of Edward, the Scottish 

 naturalist, however, shows considerable powers of observa- 

 tion on the part of frogs. After describing the great 

 noise made by a number of frogs on a moonlight night, 

 he says :

 emotions is not to be questioned. Thus, to quote from 

 Thompson : 



The common guana (Lacerta iguana) is naturally extremely 

 gentle and harmless. Its appearance, however, is much against
