He was a tall, thin man, about forty years of age, and resembled a long nail with a big head. His head was large and massive, his forehead high, his chin very marked. His eyes were concealed by enormous round spectacles, and in his look was that peculiar indecision which is common to nyctalopes[31], or people who have a peculiar construction of the eye, which makes the sight imperfect in the day and better at night. It was evident that he was a lively, intelligent man.
