- Letter from H. Mark to LP RE: Written in German. Thanks LP for his letter and the congratulations on his second boy. States that his work suffers due to the economic depression and that they had to abandon their visit to Dr. Wierl in Pasadena. Is pleased that LP also works in the electron reflection field. Will send LP a reprint of his and Wierl's results from their electron reflections. Complements LP on his research-always bringing chemistry and physics together.
