With his elbows kept on his knees, neck should be massaged briskly with fists holding balls of cloth.
Patient is made to strain by clasping his teeth, coughing and inflating cheeks, so that veins are visible.
From his back, the neck should be tied with a band of cloth and tightened with his index fingers within it; this is the mode of restraining veins except those which are inside the mouth.
