Lycinus. Purist
Ly. Are you the man whose scent is so keen for a blunder, and who is himself blunder-proof?
Pur. I think I may say so.
Ly. I suppose one must be blunder-proof, to detect the man who is not so?
Pur. Assuredly.
Ly. Do I understand that you are proof?
Pur. How could I call myself educated, if I made blunders at my age?
Ly. Well, shall you be able to detect a culprit, and convict him if he denies it?
Pur. Of course I shall.
