Lefevre at length pointed out that it would furnish definite corrobora- 
tion both of the identification of catalysis with the free energy of sur- 
faces and of the catalytic theory of immunizations, if both concurred 
to explain why, when the specific substrate for a pathegen was de- 
stroyed, that particular isomer of albumin did not form again in the 
blood serum. 
The Doctor’s answer comprises a succinct restatement of the salient 
point of both theories and gives the desired explanation, causing all 
to appear as a consistent and strongly warranted hypothesis for 
a rational comprehension of the processes of nutrition and patho- 
genic reactions: 
“It is taught that all forms of kinetic energy of matter are de- 
veloped from the heat energy of its molecules. This view has failed 
to explain the nature of chemical energy, of catalytic energy, of 
therapeutic energy, of the energy of pathogens, enzymes, and toxins. 
My theory takes a different view of the source and nature of kinetic 
energy. I claim to show that the energy of a molecule is an exact 
representation of its chemical and physical structure. This is the 
pivotal point of argument. What follows are corollaries, legitimate, 
if not inevitable conclusions deduced from this predicate. Taking 
up the text book description of molecular structure, i. e., its con- 
tained atoms, spatially placed, and moving in periods which char- 
acterize each kind of atom, I go further and assume that the moving 
atoms in the molecule produce intermolecular waves in the ether, 
which accurately correspond to the atomic motions. These waves are 
necessarily discordant, but under the operation of the law of interfer- 
ence, they become adjusted, so that crests and troughs correspond. 
I think it quite reasonable to assume that waves of this kind, falling 
millions of times a second, are waves of energy. Now the factors 
which produce such molecular waves are the number and kind of 
atoms a molecule contains, and the spatial arrangement of the atoms 
(Stereo-Chemical Configuration of the molecule) and since the chem- 
ical and physical structure of molecules are very different, the forms 
of energy they possess differ correspondingly. Such molcules have 
necessarily specific affinities, since they will re-act with other mole- 
cules, but only those whose waves they can influence, increase, re- 
tard, or destroy. 
“In chemical reactions the atoms of the dissociated molecule re- 
combine under atomic or chemical forces into other molecules, these 
combine into a mass according to molecular affinities; the crest of 
molecular waves of one side correspond to wave trough of the other 
side, the union which occurs will be in stable equilibrium, as the
