The cosmic-ray showers, which are shown so beautifully in the counter controlled cloud chamber,(1) have been investigated by numerous observers. The method in general has consisted in putting three Geiger counters below a thin plate of heavy material. The counters are usually arranged so that three particles emerging simultaneously from the plate are required to register a coincidence. Hence a shower will consist of at least three particles associated in time.
