gressive evolution of organisms, and is, therefore, anagenetic. 
Such a conclusion may seem to lead to a dualism which is itself 
opposed to the principle of continuity or uniformity, and which 
is opposed to experience of the phenomena of energy in general. 
How is uniformity to be harmonized with the hypothesis of 
two types of energy acting in different directions, apparently 
in opposition to each other? Since facts and logic do not 
support the derivation of the anagenetic from the inorganic 
energies, can the reverse process, the derivation of the cata- 
genetic from the anagenetic be and have been the order of 
nature? In support of this hypothesis, we have the universal 
~ prevalence of the retrograde metamorphosis of energy in both 
the inorganic and organic kingdoms. Phenomena of structural 
degeneracy are well known in the organic world, and purely 
chemical phenomena in both organic and inorganic processes 
are all degenerate. It appears then much more probable 
that catagenesis succeeds anagenesis as a consequence, and 
does not precede it as a cause. In other words, it is more 
probable that death is a consequence of life, rather than that 
the living is a product of the non-living. I have therefore 
given to that energy which is displayed by the plant in the 
elaboration of living from now living matter the name of anti- 
chemism! ‘Thus while the heat of the sun is necessary to the 
building of protoplasm, within a certain range of temperature, 
this form of energy has its opportunity. 
In order to present more clearly the views enunciated in the 
preceding pages, I give a synoptic table of energies.
