 been a great many more. I will only say a 

 few words on the way in which Darwin tries to 

 prove that all horses have descended from one 

 dun-striped stock. 



It appears that the Norwegian pony, a Bur- 

 mese breed of pony called the Shan, and the 

 lanky Kattywar race in India, are all often 

 or predominantly dun-striped ; besides, this 

 dun-striped colour has been noticed in in-

 a cross at a remote period could be transmitted 

 through so many generations. With regard to 

 the breeds which are predominantly dun-striped,
