GROUP II. FUNCTIONS OF NATURE 
These books will treat of the relation of facts to causes and effects—

treating of Inorganic Nature, the physical and chemical relations will be 
specially expounded; and in treating of organized creatures, the relations 
to food and climate, with the peculiarities of their functions—internal and 
external.
