most simple. If we regard them, however, solely in the light of 
the essential nature of energy, 2. e., power, we must see that the 
chemical and physical forces are most specialized. The range of 
each species is absolutely limited to one kind of effect, and their 
diversity from each other is total. How different this from the 
versatility of the vital energy. It seems to dominate all forms of 
conversion of energy, by the mechanisms which it has, by evolu- 
tion, constructed. Thus if the inorganic forces are the products 
of a primitive condition of energy which had the essential char- 
acteristics of vital energy, it has been by a process of specializa- 
tion. As we have seen, it is this specialization which is every- 
where inconsistent with life. 
With these preliminary remarks we may now consider very 
tentatively the relations of the different kinds of energy to each 
other and to consciousness, In practice it is sometimes difficult 
to draw the line between conscious and unconscious states of 
energy. One reason is, that although a given form of energy 
may be unconscious, consciousness may apprehend the action by 
Perceiving its results. The distinction is rendered clearer by the 
reflection that we can perceive by sight or touch any action of 
the body of whatever character. The energy of the conscious 
type is therefore altogether mental. The relations may be ex-

The only strictly molar energies of the above list are the cos-

ular, although they give rise to molar movements, as those of the 
muscles, of magnetism, &c. Some molar movements of organic
