Among the cosmic-ray events recorded with a multiplate cloud chamber there are twelve in which two of the new unstable particles (hyperons or heavy mesons) seem to originate in the same nuclear interaction inside the chamber. Seven events show two neutral V particles, four show one neutral and one charged V, and one a neutral V and an S particle. The histogram of the dihedral angle between the production and decay planes of the unstable particles is found to be consistent with a uniform distribution. This result does not necessarily imply small spin for the new unstable particles.
