"It's all very fine to say, don't cut that artery," remarked one of the men working on the opposite leg. "Silly old fool's got an artery in the wrong place."

"Arteries always are in the wrong place," said Newson. "The normal's the one thing you practically never get. That's why it's called the normal."

"Don't say things like that," said Philip, "or I shall cut myself."

"If you cut yourself," answered Newson, full of information, "wash it at once with antiseptic. It's the one thing you've got to be careful about. There was a chap here last year who gave himself only a prick, and he didn't bother about it, and he got septicaemia."

"Did he get all right?"

"Oh, no, he died in a week. I went and had a look at him in the P. M. room."

Philip's back ached by the time it was proper to have tea, and his luncheon had been so light that he was quite ready for it. His hands smelt of that peculiar odour which he had first noticed that morning in the corridor. He thought his muffin tasted of it too.

"Oh, you'll get used to that," said Newson. "When you don't have the good old dissecting-room stink about, you feel quite lonely."

"I'm not going to let it spoil my appetite," said Philip, as he followed up the muffin with a piece of cake.
