A variant of the theory is proposed in which non-conservation of parity can be introduced without assuming symmetry of space with respect to inversion. Various possible consequences of non-conservation of parity are considered which pertain to the properties of the neutrino and in this connection some processes involving neutrinos are examined on the assumption that the neutrino mass is exactly zero.
