Two reports are presented. 1 The ideal ice lattice without defects would show neither dipole orientation polarization nor conduction. In real ice crystals the author distinguished seven relaxation spectra in the frequency range between 100,000 and 0.008 Hz. The paper re-examines the experimental evidence and tentatively assigns molecular processes to the spectra. 2 After a short discussion of Ice Chemistry, the authors focus on the specific question Is Ice Ih a proton semiconductor. A critical analysis of the original experiments by Eigen, De Maeyer and Spatz on multicrystalline samples and new experiments on single crystals lead to a negative answer. Author
