In place then of the innumerable individu- 

 als a certain genealogical ascent has succes- 

 sively entailed, let us imagine one individual 

 accomplishing the whole of it. The final 

 result as regards structure might conceivably 

 be substantially the same, nor need the time 

 required be very different. But there would 

 certainly be one very important difference. 

 For the solitary immortal without ancestry 

 structure would be wholly the result of
