Normality is not hereditary
This article gives the statement, and possibly proof, of a topological space property (i.e., normal space) not satisfying a topological space metaproperty (i.e., subspace-hereditary property of topological spaces).

This article gives the statement and possibly, proof, of a non-implication relation between two topological space properties. That is, it states that every topological space satisfying the first topological space property (i.e., Normal space (?)) need not satisfy the second topological space property (i.e., Hereditarily normal space (?))
