{ *  Abundances of M~13 BHB stars are from Behr (\cite{Behr00c}) and
abundances of M~13 RGB star are from Cavallo \& Nagar (\cite{Cavallo00}). In the last
column, the mean abundances of elements from Na to Fe in M~13 RGB stars 
are from Kraft et~al. (\cite{Kraft97}) and that of Y and Ba are from Armosky et~al. 
(\cite{Armosky94}). }
