 ence of what we may consider a<? evils, or at best as useless 

 Animals, without our being able to comprehend the pur- 

 poses for which all things are made. 



The Amphibeae are divided in two natural families oi 

 orders ; in the first of which are placed those Animals that 

 possess feet or fins ; and the second contains those destitute 

 of feet. The whole class are cold blooded ; their bones car- 

 tilaginous ; in some, the respirative organs are large, but in 

 all are imperfectly defined ; their respiration is slow, as h 

 also their powers of digestion, and the circulation of the.vKal 

 fluid ; most of thern are very tenacious of life^ some possess 

 the power of reproducing parts that have been destroyed 

 or mutilated ; many species are amphibious, others 

 entirely aquatic, surviving but a very short time on being 

 removed out of water ; whilst many other kinds cannot sur- 

 vive in it. A considerable proportion of those ioliabiting the 

 colder parts of Europe, Asia, and America, become torpid 

 during winter.

Of the Animals in this Order, a considerable number are 

 entirely aquatic, only approaching land for the purpose of 

 depositing their eggs; these are confined to the first ge/)iiSj 

 the whole of which consists of Animals covered with a hard,
