favourite formula. It never entered his head that 

 there could be a confusion instead of a correlation, 

 and that there might be only one and the same act, 

 the phases of which would be indistinguishable. 

 This unfortunate idea, which was fated to be so 

 rapidly contradicted, is due to Le Dantec. Far 

 from it being the case, Pasteur had distinguished 

 the ferment function from the life of the yeast. 

 According to him, the yeast may exist sometimes as 

 a ferment and sometimes otherwise. 



§ 3. Correlation of Two Orders of 

 Vital Facts. 



Jt is this correlation between acts distinct in them- 

 selves but usually connected that was announced by 

 Claude Bernard. And, mirabile dictu — and this is the 

 natural outcome of the perfect sanity of mind of this 

 great physiologist — it happens that not only Pasteur's 

 researches, but the development of a new science. 

 Energetics, and Biichner's discovery lend support to 

 his views, and that, too, in a field where one would 

 have thought they had no application. Le Dantec is 

 wrong when he declares that these ideas only apply to 

 vertebrates; "It is clear," he says on several occa- 

 sions, *' that the author has in view the metazoa and 

 even the vertebrates." Well • ho. All that is general, 

 universally applicable, and universally true. So that 

 there are two orders of distinct phenomena ener- 

 getically opposed and certainly connected. We need 

 only repeat Claude Bernard's own words quoted by 

 Le Dantec in order to confute them.
