92 MAMMALIAN DESCENT. [Lect. IV,

 tinued existence was pronounced upon them. Now, 

 the Serpents, as it seems to me, are among the 

 worthiest of all those that had power with their antago-

 were almost gone, and when the roots of their limbs

If life had not been a struggle with the angel of 

 death, our existing Edentata might have been left by 

 nature, as defenceless as the first human types. They 

 were, however, her dull, but dear, children ; and she 

 helped them as she did not help us and our ancestors. 

 She did not change her plans for them ; but she clothed 

 some witii a thick heav}^ fell of hair, and others she 

 harnessed with coats of mail. 



What science wants to embody forth is the primordial 

 root-form of all the nobler creatures now existing ; all 

 those, I mean, that begin life by breathing air, all the 

 forms above the Amphibia (Frogs and Toads, Newts 

 and Salamanders). Indeed, we need the conception of 

 a still lower root-form than the Tadpole or the larval 

 Newt, one which might possibly have been the parental 

 form of all the existing Vertebrata. 



Let us imagine such a primordial form, and then we 

 can argue that the lowest existing Vertebrates, the Hag 

 and the Lamprey, are the descendants of t}i3es that have 

 had as much leisure for improvement as the forefathers 

 of the noblest kinds. All these types, during countless.
