55ac, 'Dora and Maud each do show great kindness', (4,1,5,2,4), ?A?E ? H?A?T ?F ?O?D. 'Have a heart of gold', presumably, but what is the construction?
The words Dora and Maud have "a heart of gold" as they have Or and Au at their centres or hearts. Or is a name for gold in heraldry and Au is its chemical symbol.
