THE METHOD OF CREATION. 297 



form the body walls and the other the digestive organs. Some 

 curious accessory parts appear. Next, the divisions of the 

 brain-regions appear, and the vertebrae increase in number. 

 The heart begins to beat as a flask-shaped organ ; two aortee 

 result from its division ; and other blood-vessels arise, but 

 only of a temporary character. Blood cells appear ; the sec- 

 ond and third divisions of the brain are differentiated ; also, 

 the beginnings of eyes and ears. Bronchial fissures appear in 

 the sides of the neck. Thus the development proceeds. I ^ 

 wish to mention only details enough to show that the embry- 

 onic history of an animal is a fine exemplification of Nature's,' 

 method material continuity, and progress from the more 

 general to the more detailed. The history of the individual / 

 is often called Ontogeny. 



But what now, of the assemblage of animals living on the 

 earth? There are many different species; there are very 

 divergent classes; has not each separate species, or at least, 

 class, had a separate beginning ? Let us consider. There are 

 no two animals precisely alike. There is diversity in a single 

 litter of kittens. There are no two men or women precisely 

 alike. Even the same man differs from himself as a boy or a 

 babe, and differs to a very great extent. But two persons, 

 though differing, may be brothers; and though differing they 

 may have very pronounced family resemblances. Two men 

 who are cousins may show less distinct resemblance because 

 their relationship is more remote, as we would explain it ; but 

 still there is a real resemblance ; and we feel safe in declaring 

 it to arise from a real blood-relationship. So all the members 

 of the Napoleon family, or the Potter family, may show some 

 common cast of features which reveals their blood affinity. 

 We feel sure of this. 



Similar family resemblances may be traced among lower 

 animals. Take the domestic cats; how wide their divergences, 

 yet how close their resemblances. These animals we know 

 possess a common lineage, and by that we explain their resem- 

 blances, in spite of their divergences. But in the cat-family 

 at large, are several other forms which differ from the domestic
