that the flefhy part of the tail of the tadpole ftill 
remains after the animal has acquired its complete 
form; but this is by no means the cafe: not the leaf!:

perhaps all the fpecimens of thefe very large tad¬ 
poles which occur in Mufeums, may not be thofe 
of the rana paradoxa in particular, but of fome other 
fpecies of American, African, or Aliatic frogs, as 
the rana ocellata, marina, &c. &c.
