Si mutare potest Æthiops pellem suam, aut pardus varietates suas, et vos poteritis benefacere, cum didiceritis malum.
If the Ethiopian can change his skin, or the leopard his spots: you also may do well, when you have learned evil.
Si muta pote Aethiope pelle suo, aut pardo varietates suo, et vos pote beneface, cum disce malo.
