Details are given of six hyperon events observed in photographic emulsions. Two of these decay at rest into protons and give Q-values of 115.8±1.0 MeV and 113.5±1.7 MeV for the assumed decay scheme: Y+ → p+π0+Q. Three others decay in flight; two give Q-values 115±7 MeV and 103±10.5 MeV for the decay mode: Y± → n+π±+Q; the third is in agreement with the cascade type of decay: Y- → A0-+Q and has a Q=59±11 MeV. The sixth event has been interpreted as the interaction at rest of a negative hyperon; from the parent star of this hyperon there also emerges a K-meson.
