iv. COUSIN SARAH. 67 



her allies on the one hand, and you and me on the other. 

 We are all built upon the same plan, and even in details 

 the resemblances are very close. Except that Sally has 

 an extra pair of ribs, her bones answer to your bones each 

 to each. I do not mean that they answer to yours in 

 precise shape; the shoulder-blades and collar-bones for 

 example are not quite like yours ; but they answer closely 

 in number and general arrangement. So too with the 

 other parts. There is a plane of correspondence deeper 

 than the superficial points of diversity. And Sally is not 

 less admirably fitted for her natural mode of life than you 

 for yours. Her brain is not so highly developed as yours ; 

 but she has the best of it in muscular power. Her hand 

 is not so delicate an organ or capable of such nice adjust- 

 ment as yours ; but her foot is prehensile which yours is 

 not. Hence some differences of structure and muscular 

 equipment. But on the whole the resemblances are so 

 close that most anatomists include man and the anthro- 

 poid apes in the same group. In doing so, you must 

 remember, they are guided by structure alone ; for in 

 classification it is to this we must look, and not to intel- 

 lectual and moral characters. And we may consistently 

 believe that although these high qualities, and the power 

 of speech in and through which they have arisen, alto- 

 gether mark off and distinguish man from the rest of the 

 animal kingdom, yet still, in his structure and organiza- 

 tion, he is one with the anthropoid apes ; and that, so 

 far, he may not deny to Sally the title of " Cousin Sarah."
