A considerably large east-west asymmetry of cosmic radiation with high energy has been observed using two narrow angle counter telescopes with altazimuth mountings at Nagoya. This observation is interpreted as the result of deflection by earth's magnetic field of the μ-mesons produoed from primary particles in the atmosphere. Since this component contains about twenty percent more positive than negative mesons, the asymmetry was explained in terms of the opposite deflection for positive and negative mesons and their finite life times. The asymmetry calculated theoretically in this way agrees with the observed data.
