While giving his directions, he unbound the arm, enlarged the wound in the vein longitudinally, and re-bound the arm tight below the elbow, then quickly opened a vein of his own, and held the syringe to catch the spout that followed.

When it was full, he replaced the piston, telling Mrs.
Puckridge to put her thumb on his wound, turned the point of the syringe up and drove a little out to get rid of the air, then, with the help of a probe, inserted the nozzle into the wound, and gently forced in the blood.

That done, he placed his own thumbs on the two wounds, and made the woman wash out the syringe in clean hot water.

Then he filled it as before, and again forced its contents into the lady's arm.

This process he went through repeatedly.
