Abstract: (IOP)

The authors' previous claim (1980, 1981) for an excess of cosmic-ray showers coming from the general direction of the Crab nebula has been strengthened by observation of the effect in other data not examined previously. The nature of the particles responsible for the showers is not clear. There is a reduced muon content, suggestive of primary gamma rays (Egamma approximately=1016 eV) but protons cannot be ruled out. If photons are responsible, a sharp cut-off in the energy spectrum above a few times 1016 eV is indicated in view of the non-observation of a signal in other experiments in this energy range.
