   Therefore it is not correct to say that all claims decucible from   
   general knowledge are in general knoledge. The claims that are   
   deducible from general knoledge but neither known to be deducible from   
   the common knowledge nor ottherwise knwon are not in general knowledge.   
   This is an incompleteness in general knowledge.
