EXTINCT ANIMALS 



Thames many thousands of years ago. That 

 specimen also is in the Natural History Museum. 



Here (Fig. 6) you have a thigh bone ; you 

 can see how enormous it is from the figure of 

 the full-grown man beside it. That is the 

 thigh bone of a huge kind of reptile, bigger 

 than the ordinary elephant, or the biggest 

 African elephant, without counting the rep- 

 tile's tail. Such remains have been found 

 in England ; but the largest have been found 

 in the United States. 



These are just a few samples of the remains 

 of extinct animals, and indicate the kind of 

 creatures I want to tell you about. Of course 

 I cannot in these pages refer to all the many 

 thousands of kinds of extinct animals which are 

 known ; I can only hope to show you pictures 

 of a few samples of these things, which, how- 

 ever, I hope will suffice to induce you to look 

 further into the matter, to look at the real 

 specimens, and to read more elaborate books, 

 and thus come to feel the same interest and 

 pleasure in examining them that I do myself. 



The world upon the surface of which we live 

 has been for millions of years always changing. 

 Nothing is to-day as it was even one hundred
