$^{a}$ For PB~8, O$^{++}$/H$^+$ derived from ORLs and O$^+$/H$^+$ from CELs and {\tsq}. For NGC~2867  we have adopted an ICF to correct for unseen ionization stages (see text).\\
$^{b}$ C/H~=~ICF(C)~$\times$~C$^{++}$/H$^{+}$. \\
$^{c}$ C/H~=~ICF(C)~$\times$~(C$^{++}$/H$^+$+C$^{3+}$/H$^+$+C$^{4+}$/H$^+$).
