 kingdom is under consideration, and in either

And one last word on this point : the 

 Luminiferous Ether is a collection of apparent 

 antinomies postulated to explain the undula-

 says, gives itself away only by the perfectly 

 uniform manner in which it transmits not only 

 light but other things, such as electric and 

 magnetic waves. Is there really more evidence 

 even as much evidence for the Ether as 

 there is for the Entelechy ?
