"Let's slip on our coats," Jim suggested.

"The others don't do it," said Mark, glancing at a row of shivering boys, "and we won't."

After what seemed an interminable interval, Jim's name was called. The doctor into whose hands he fell made short work of him. He clapped a stethoscope to his chest and back, looked at his legs, asked a few questions, and smiled pleasantly. "If you can see and hear, you're all right," said he. "Next!" Jim went back to where his clothes lay in a heap on the chair. He knew that his sight and hearing were excellent; but why in the name of all that was hateful did not Mark come back? Half-way down the room Jim could see him, standing in front of a small, ferret-faced man, who was talking quickly. Now, Jim had not been asked to run round a table or to perform any other strange exercises, but Mark was treated less kindly. Jim saw him jump on and off a bench; then he began to run, and Jim caught the quick command: "Faster, sir, faster!" And then the stethoscope was laid upon his heaving chest. Jim watched the doctor's impassible face. Suddenly the doctor looked up and beckoned to the man who had examined Jim. The second doctor put his ear to the stethoscope.

"Catch him!" yelled Jim.

A hush fell upon the big room as Jim sprang forward, half clothed and choking with excitement. He had seen Mark quiver and reel, but the tall, thin doctor had seen it too. When Jim reached them, Mark was on his back on the big table. The ferret-faced man was smiling disagreeably, and tapping the palm of his hand with the end of his stethoscope.

"Absolutely unfit," Jim heard him say. "Not a surgeon in London would pass him."

"Not pass him?" Jim said furiously. "He's only fainted; he's done that before, that's nothing."

"Isn't it?" said the little man drily. Then he added malevolently: "When I am ready to receive instruction from you, young sir, I will let you know."

When they got back to the hotel and were alone, Mark flung himself into an armchair. Presently he said quietly: "Let's get seats for the play"; so they walked as far as Mitchell's in Bond Street, and bought two stalls for the Colleen Bawn, in which Dion Boucicault was acting. Then they strolled on to Regent's Park. Not a word was said about what passed in Burlington House till they were crossing Portland Place, where a cousin of Mark's had a house.

"I shan't go back to Pitt Hall till your exam is over," Mark said. "I'd sooner stop up here with you."
