 precise definition and the purely logical deductive method, as unsuited to 

 a science at present incompletely known, we may construct a physical theory, 

 indefinite in parts and incomplete in details, but nevertheless available for 

 co-ordinating the results obtained by physical investigation, and capable of 

 being itself advanced towards perfection thereby.
