He stared away from me towards the diagrams of cryohydrates. "I must be deaf," said he. "They've fired a gun, for there goes the puff of smoke, and I never heard a sound."
I put my hand on his arm again, and this time he was less alarmed. "We seem to have a sort of invisible bodies," said he. "By Jove! there's a boat coming round the headland. It's very much like the old life after all--in a different climate."
I shook his arm. "Davidson," I cried, "wake up!"
It was just then that Boyce came in. So soon as he spoke Davidson exclaimed: "Old Boyce! Dead too! What a lark!" I hastened to explain that Davidson was in a kind of somnambulistic trance. Boyce was interested at once. We both did all we could to rouse the fellow out of his extraordinary state. He answered our questions, and asked us some of his own, but his attention seemed distracted by his hallucination about a beach and a ship. He kept interpolating observations concerning some boat and the davits and sails filling with the wind. It made one feel queer, in the dusky laboratory, to hear him saying such things.
He was blind and helpless. We had to walk him down the passage, one at each elbow, to Boyce's private room, and while Boyce talked to him there, and humoured him about this ship idea, I went along the corridor and asked old Wade to come and look at him. The voice of our Dean sobered him a little, but not very much. He asked where his hands were, and why he had to walk about up to his waist in the ground. Wade thought over him a long time--you know how he knits his brows--and then made him feel the couch, guiding his hands to it. "That's a couch," said Wade. "The couch in the private room of Professor Boyce. Horsehair stuffing."
Davidson felt about, and puzzled over it, and answered presently that he could feel it all right, but he couldn't see it.
"What _do_ you see?" asked Wade. Davidson said he could see nothing but a lot of sand and broken-up shells. Wade gave him some other things to feel, telling him what they were, and watching him keenly.
"The ship is almost hull down," said Davidson, presently, _apropos_ of nothing.
"Never mind the ship," said Wade. "Listen to me, Davidson. Do you know what hallucination means?"
