His complexion, for instance, has a singular sallow-fairness, so much at variance with the dark-brown colour of his hair, that I suspect the hair of being a wig, and his face, closely shaven all over, is smoother and freer from all marks and wrinkles than mine, though (according to Sir Percival’s account of him) he is close on sixty years of age. But these are not the prominent personal characteristics which distinguish him, to my mind, from all the other men I have ever seen. The marked peculiarity which singles him out from the rank and file of humanity lies entirely, so far as I can tell at present, in the extraordinary expression and extraordinary power of his eyes.
