Stantiated only by undertaking a thorough discussion of the

general relations which they bear to each other, or, in other 
words, recognize the mutual dependence and essential correlation 
of special physical forces. ‘ : : 
The established truths and generally received ideas, which

of force upon matter. oan 
2. All the forces in operation in nature are traceable to two 
primary forces, viz: attraction and repulsion. = 
3. All bodies of matter consist of separate indivisible parts, 
called atoms, each of which is conceived to be spherical in form, 
4. Matter exists in three different forms, essentially different 
from each other, These are: (1) ordinary, or gross matter, of
