The punctures (three or four in number) are best made from above, so that the lymph may gravitate into them, and should not draw more than a trace of blood ; they should not be made so close together as to cause the resulting vesicles to become confluent. The vaccine lymph is best taken from the fully formed vesicle of a healthy child at the time, but may be preserved on ivory points, between glasses,—or better, in glass tubes. If points are used, they should be moistened with the breath before being inserted
