may De-energize the Former but not the La'ter—Experi- 
ments with Infusions of Different Strengths tend to Prove 
this—Reasons for Believing the Delayed Putrefaction in 
Inoculated Organic Fluids Heated to 140° F. to be due to 
the Mere Organic Matter of the Inoculating Medium— 
Proof of this—And proof by New Experiments that 
Bacteria and their Germs are Killed in Organic Fluids 
Heated to140°F. . . 
Uniformity of Evidence as to Death-point of Living 
Ferments—Important Difference between Living and Not- 
Living Ferments as regards their Power of Resisting Heat 
—This Point of View Steadfastly Ignored by M. Pasteur 
and his Followers—A bsence of all Evidence to Show that 
Heat is Less Destructive to Living Matter in Some Fluids 
than in Others —M. Pasteur’s Experiments never Distinctly 
capable of Supporting such a Conclusion—He Ignored an 
Equally Possible though Opposite Interpretation whose 
Truth has been now Established . 
Inadequacy of M. Pasteur’s ‘ Vital Theory’ of Fermen- 
tation—What New Experiments Teach—Three Degrees 
of Fermentability — Self-Fermentable Fluids — Tabular 
Statement Concerning—Second Degree of Fermentability 
—Explanation of M. Pasteur’s Celebrated Experiments in 
which he Sowed mere Organic Fragments and called 
them ‘Germs’— Explanation of Other Experiments— 
Origin of Torula—Meaning of their Appearance—Fer- 
mentation may gradually Merge into Putrefaction—Third 
or Lowest: Degree of Fermentability—Fluids which only 
Change under Influence of Most Potent Ferments (Living 
Organisms) — Uniformity of Results in Inoculation Experi- 
ments—This Adverse to Explanation of Cases of Delayed 
or Smouldering Fermentation by M. Pasteur’s Theory— 
Living Ferments Act Promptly and with Regularity 
—wNot-living Ferments often Act Slowly and with Great 
Irregularity—Results of Several Series of Different Experi- 
ments point to Archebiosis as the only Means of Recon- 
ciliation—Conclusions. . . .
