An expression of intense solemnity came over his face, and he sat motionless gazing in front of him with unblinking eyes. I crossed to where he sat and peered at his face.

"I thought so," I remarked. "You've got it too."

"Got what?"

"The Blue Disease. I suppose you caught it from Wain, as we did." I picked up one of his hands and pointed to the faintly-tinted fingernails. Dr. Symington-Tearle stared at them with an air of such child-like simplicity and gravity that Sarakoff and I broke into loud laughter.

The humour of the situation passed with a peculiar suddenness and we ceased laughing abruptly. I sat down at the table, and for some time the three of us gazed at one another and said nothing. The spirit-lamp that heated the silver dish of bacon upon the table spurted at intervals and I saw Symington-Tearle stare at it in faint surprise.

"Does it sound very loud?" asked Sarakoff at length.

"Extraordinarily loud. And upon my soul your voice nearly deafens me."

"It will pass," I said. "One gets adjusted to the extreme sensitiveness in a short time. How do you feel?"

"I feel," said Symington-Tearle slowly, "as if I were newly constructed from the crown of my head to the soles of my feet. After a Turkish bath and twenty minutes' massage I've experienced a little of the feeling."

He stared at Sarakoff, then at me, and finally at the spirit lamp. We must have presented an odd spectacle. For there we sat, three men who, under ordinary circumstances, were extremely busy and active, lolling round the unfinished breakfast table while the hands of the clock travelled relentlessly onward.
