greater than between electrical effect and any effects produced by 
heat, or by gravitation, or by any other of the forces of inorganic 
natu ure, It would be far more rational to attribute all the phe- 
nomena of the inorganic world, say, to heat, than to attribute the 
jue of molecular motion in the organic world to chem-

It must now be obvious that nothing which can be determined 
by the comparative Se caRee no o biological researches, n o mi

in the building-up process the determinations of molecular motion 
were different in the two cases; and the true and fundamental 
ground of the difference must be sought for in the cause of the

determination of molecular motion. Here in this region the doc-
