208 THE NEXT GENERATION 



CHAPTER VI 



Where are horses found ? What can be said about their resem- 

 blance and relation to each other ? What is a fossil (see footnote) ? 

 In what special museum in New York City do we find large num- 

 bers of fossil bones ? How are the horse bones grouped in the 

 museum ? So far as size is concerned, how do they progress ? 

 Speak of the difference between the largest horse skeleton and the 

 smallest. If these were alive to-day, would they treat each other 

 as friends or as strangers ? What remarkable fact do the graded 

 horse bones prove ? How long did the small horse live before the 

 large one ? During that time, what changes took place in legs 

 and jaw and skull bones ? Describe the foot as it changed into 

 a hoof. What part of the middle toe finally became the hoof ? 

 What became of the other toes ? What sign of toe is there on 

 the legs of a modern horse ? Where are these splint bones ? While 

 the toe bones were changing, what happened to the jaw bones 

 and the teeth of the horse ? What explains the gap between the 

 front teeth and the back teeth of a modern horse ? When the 

 smallest and earliest horse bones first came to light, what name 

 was given to the little creature ? Where have many fossil horse 

 bones been found ? What connections have been traced ? How 

 many sets of scientists are needed to explain buried bones ? What 

 does the geologist do ? What does the paleontologist do ? What do 

 we learn from fossil bones ? 



Which set of bones gives the most straight-ahead, complete his- 

 tory of the animal ? In what countries have fossil horse bones been 

 found ? Where does this best series come from ? If a horse could 

 think and talk, what might he say about his ancestors ? 



CHAPTER VII 



Where did Darwin keep his angleworms ? What did he know 

 about their different senses ? What questions did he ask himself 

 about them ? Why are angleworms studied at night ? Describe 

 their actions as Darwin saw them. When did Darwin's interest in 

 angleworms begin ? What does Darwin say about the matter ?
