His very person and appearance were such as to strike the attention of the most casual observer. In height he was rather over six feet, and so excessively lean that he seemed to be considerably taller. His eyes were sharp and piercing, save during those intervals of torpor to which I have alluded; and his thin, hawk-like nose gave his whole expression an air of alertness and decision. His chin, too, had the prominence and squareness which mark the man of determination. His hands were invariably blotted with ink and stained with chemicals, yet he was possessed of extraordinary delicacy of touch, as I frequently had occasion to observe when I watched him manipulating his fragile philosophical instruments.

He found him a tall figure, with a slightly flabby body, shining hair and well-trimmed beard. He appeared impressive, well-dressed and his eyes were exceptionally eloquent that drew everyone’s attention. There was deep note of mystery about his eyes...His style of conversation was always accompanied by his smile and too attractive which cast a spell on his addresses...He had a remarkable ability to assess others and immediately found out their mental level and their taste. Likewise, he had an enviable understanding of the context and situation in which he found himself placed.
