The paper describes microscopic investigation into the spectral distribution of photo-luminescence and its polarization on hexagonal ZnS monocrystals in relation to the structural defects of such crystals. These observations, as well as birefringent observation, show that the values of the birefringence and the degree of polarization in different stripes of the same crystal are the same within the limits of observational error.

Great Britain. The initiation of electrical breakdown between metallic electrodes insulated by high vacuum has been studied by many authors. One of the explanations offered is the removal of aggregates of material from the anode and their bodily transfer to the cathode. The objection to this mechanism is the fact that the electrostatic forces prior to breakdown appear insufficient to tear particles out of the solid surface and that the presence of loose aggregates cannot be relied on. The author suggests that in the case of copper the material transferred is made up of dentritric inclusions. On account of the low cohesive force between inclusion/metal interfaces, an electrostatic stress of the order of lo3 dyn/cm would suffice to pull out such an inclusion whilst the actual disruption of the solid metal W. J. S. is many magnitudes higher than this.
