"Is it for extreme unction?" Hans ventured to ask.

"For a marriage," answered Helen.

Five minutes later the doctor returned with his apparatus, and asked Benedict to ring for a servant.

A maid came.

"Some warm water in a deep vessel," said the doctor, "and a thermometer if there is one in the house."

She came back with the required articles.

The doctor took a bandage from his pocket and rolled it round the wounded man's left arm, the right arm being injured. After a few moments the vein swelled, proving thereby that the blood was not all exhausted, and that circulation still continued, although feebly. The doctor then turned to Helen.

"Are you ready?" he enquired.

"Yes," said Helen, "but make haste. Oh, God, if he should die!"

The doctor compressed her arm with a bandage, placed the apparatus upon the bed so as to bring it close to the patient, and put it into water heated to 35 degrees centigrade, so that the blood should not have time to cool in passing from one arm to the other. He placed one end of the syringe against Karl's arm and almost simultaneously pricked Helen's so that her blood spurted into the vessel. When he judged that there were some 120 to 130 grammes he signed to Benedict to staunch Helen's bleeding with his thumb, and making a longitudinal cut in the vein of Karl's arm he slipped in the point of the syringe, taking great care that no air-bubble should get in with the blood. While the operation, which lasted about ten minutes, was going on, a slight sound was heard at the door. It was the priest coming in, accompanied by Emma, Madame von Beling, and all the servants. Helen turned, saw them at the door, and signed to them to come in. At the same moment Benedict pressed her arm; Karl had just quivered, a sort of shudder ran through his whole body.
