In another second there was a simultaneous rush upon the struggle, and a stranger coming into the road suddenly might have thought an exceptionally savage game of Rugby football was in progress. And there was no shouting after Kemp's cry--only a sound of blows and feet and heavy breathing.

Then came a mighty effort, and the Invisible Man threw off a couple of his antagonists and rose to his knees. Kemp clung to him in front like a hound to a stag, and a dozen hands gripped, clutched, and tore at the Unseen. The tram conductor suddenly got the neck and shoulders and lugged him back.

Down went the heap of struggling men again and rolled over. There was, I am afraid, some savage kicking. Then suddenly a wild scream of "Mercy! Mercy!" that died down swiftly to a sound like choking.

"Get back, you fools!" cried the muffled voice of Kemp, and there was a vigorous shoving back of stalwart forms. "He's hurt, I tell you. Stand back!"

There was a brief struggle to clear a space, and then the circle of eager faces saw the doctor kneeling, as it seemed, fifteen inches in the air, and holding invisible arms to the ground. Behind him a constable gripped invisible ankles.

"Don't you leave go of en," cried the big navvy, holding a blood-stained spade; "he's shamming."

"He's not shamming," said the doctor, cautiously raising his knee; "and I'll hold him." His face was bruised and already going red; he spoke thickly because of a bleeding lip. He released one hand and seemed to be feeling at the face. "The mouth's all wet," he said. And then, "Good God!"

He stood up abruptly and then knelt down on the ground by the side of the thing unseen. There was a pushing and shuffling, a sound of heavy feet as fresh people turned up to increase the pressure of the crowd. People now were coming out of the houses. The doors of the "Jolly Cricketers" stood suddenly wide open. Very little was said.

Kemp felt about, his hand seeming to pass through empty air. "He's not breathing," he said, and then, "I can't feel his heart. His side--ugh!"

Suddenly an old woman, peering under the arm of the big navvy, screamed sharply. "Looky there!" she said, and thrust out a wrinkled finger.

And looking where she pointed, everyone saw, faint and transparent as though it was made of glass, so that veins and arteries and bones and nerves could be distinguished, the outline of a hand, a hand limp and prone. It grew clouded and opaque even as they stared.

"Hullo!" cried the constable. "Here's his feet a-showing!"
