Edward Malone, the narrator of The Lost World___ describes his first meeting with the Professor:
His appearance made me gasp. I was prepared for something strange, but not for so overpowering a personality as this.
It was his size, which took one's breath away – his size and his imposing presence. His head was enormous, the largest I have ever seen upon a human being. I am sure that his top hat, had I ventured to don it, would have slipped over me entirely and rested on my shoulders. He had the face and beard, which I associate with an Assyrian bull; the former florid, the latter so black as almost to have a suspicion of blue, spade-shaped and rippling down over his chest. The hair was peculiar, plastered down in front in a long, curving wisp over his massive forehead. The eyes were blue-grey under great black tufts, very clear, very critical, and very masterful. A huge spread of shoulders and a chest like a barrel were the other parts of him which appeared above the table, save for two enormous hands covered with long black hair. This and a bellowing, roaring, rumbling voice made up my first impression of the notorious Professor Challenger.
