WHAT IS PHYSICAL LIFE 



until it may become invisible; but every 

 part of it can be then experimentally ac- 

 counted for. Not so with life. It goes 

 at death no one knows where, and never 

 does it return to that matter which it once 

 made living, whether it be in a flower, in 

 an insect, or in a man. 



In the face of this mystery one natural 

 conclusion was that life is like nothing else, 

 and coming originally from its Creator, it 

 entered the various living forms on earth 

 as they were ready made for it. Milton 

 in his Paradise Lost describes the process 

 itself of this making as quite parallel to 

 the hand-made productions of us human 

 beings, and this conception of the word 

 " create " still holds its place in the com- 

 mon term creatures, applied to animals as 

 the most living of things. This unique 

 event of the creation of living forms was 

 readily supposed to have had a historical 

 date not very far back in time.
