EXPERIMENTAL ORGANISM. 



machine grows of itself, builds itself up, and multiplies, 

 while every non-living machine is made, does not grow, and 

 does not produce machines like itself. Mr. Grove further says 

 that in the human body we have chemical action, electricity, 

 magnetism, heat, light, motion, and possibly other forces 

 " contributing in the most complex manner to sustain that 

 result of combined action which we call life." Here it 

 seems to be affirmed that forces sustain the result of their 

 own combined action, but surely this is only asserting that 

 these forces sustain themselves. Heat, light, electricity, etc., 

 sustain the result of the combined action of heat, light, 

 electricity. It is moreover said that what we call life is the 

 result of the combined action of motion, heat, light, elec- 

 tricity, etc., which are but different forms or modes of one 

 force. But as everybody knows we may have any and all 

 modes of force without life. Life therefore involves some- 

 thing besides force, or is something different from it.
