Abstract
Morrison and Pfirsch derived expressions for plasma wave energy using the formalism of Van Kampen modes, apparently unaware of earlier work of Best on the same subject by the same method. It is stressed in this Comment that energy density, rather than total energy, is the relevant physical quantity.Keywords
