By assuming periodic discrete electronic spectra, the properties of small metal particles are analyzed. The canonical partition function is obtained exactly. The heat capacity and the electronic magnetic susceptibility are calculated in the presence of a static magnetic field. These results are an extension of the calculations for an equally spaced spectrum. Preliminary considerations of the statistical theory of spectra are included.
