The authors described a small electric exhaust pump with valves permitting accurate (time) application of the desired degree of vacuum. When the vacuum is applied, an electric clock is automatically started, which cuts off the former after exactly one minute. The apparatus is made by the firm of H. Junghans, Zurich. The glass bell of the device may be replaced by a vacuum jar for pleural aspiration.
