Demonstrations of the H. N. method of artificial respiration.

Several male and female subjects are shown receiving artificial respiration by the application of pressure on the upper back and "pumping" the arms in a butterfly motion. The demonstration takes place alongside an open-air swimming pool. A male subject is shown mid-torso laying on his front with another man applying pressure to his shoulder blades. The subject's arms are raised to shoulder height and the man flexes them in a butterfly motion. Intertitle indicates that the "bust" of the victim is unclothed to show this movement. The second subject is a young boy, although the person demonstrating the technique is a woman. The same procedure happens with a young girl and an older male demonstrator. A young woman performs the procedure on another girl. An intertitle indicates that when life has returned, the arms need not be raised; a sideways shot demonstrates this.
