280 WHAT 18 LIFE 



by laboratory test, will amount to conclusive proof 

 that the quantity that escapes is life, because 

 the establishment of this fact is the last link that is 

 needed in the chain of evidence that supports the 

 theory. The peculiarities of the organism, including 

 the "truly psychical," would seem to be accounted 

 for on the theory. The burden of proof will rest upon 

 him who would aflfirm something else needed. 



That the physical laboratory can establish the 

 propositions of the theory experimentally — if they 

 correctly state the facts — is not open to doubt. 



That physical laboratory research will supply the 

 direct experimental proof of the theory that is de- 

 manded, reasonably may be expected; since it would 

 appear that the theory is in entire accord with and 

 fully supported by all known facts.
