Doctor [John] Gillies, the historian of Greece, and Mr. [Richard] Porson used now and then to meet. The consequence was certain to be a literary contest. Porson was much the deeper scholar of the two. Dr. Gillies was one day speaking to him of the Greek tragedies, and of Pindar’s odes. ‘We know nothing,’ said Dr. Gillies, emphatically, ‘of the Greek metres.’ Porson answered, ‘If, Doctor, you will put your observation in the singular number, I believe it will be very accurate.’
