The purpose of this investigation was to study the temperature dependence of electrical resistivity of thorium and titanium and to determine whether or not the slope of the resistance versus temperature curve of these metals exhibit anomalous discontinuities. Iron was also studied in an attempt to reproduce previously reported results on discontinuities in the slope of the resistance versus temperature curve for this metal.
