The present state of theories of neutrinos and experimental analyses of the interaction of neutrinos with matter are discussed. It was observed that the results of experiments carried out to date relate to two general problems: the nature of the neutrino as an elementary particle and the agreement of the predictions of theories of weak interactions with experimental evidence. Data indicate that there exists four different neutral particles of spin 1/2 and rest mass equal to or very near zero; the electron neutrino and antineutrino, and the meson neutrino amd antineutrino. They are identified by their origin. The neutrino and antineutrino in both cases differ in polarization (spin direction). No difference was found between the interaction of the electron neutrino (or antineutrino) or the meson neutrino (or antineutrino) with matter. No disagreement between experiment and the predictions of the universal theory of weak interactions was observed in the laboratory up to neutrino energies of about 500 Mev. (TTT)
