In 1881 he studied Kelvin's investigation of the law of distribution of electricity in equilibrium on an uninfluenced spherical bowl and made the addition of finding the potential at any point of space in zonal harmonics.

||1851: Lorenz Oken dies ... German naturalist who offered early evolutionary ideas and stimulated comparative anatomy. He theorized (incorrectly) that the skull was a modified vertebra, but formed some fundamental concepts which stimulated further thought from later scientists. In Die Zeugung, he discussed “the infusoria”—elementary units of living organisms—into which all flesh can be broken down. Higher animals, he proposed, consisted of constituent animalcules. Entities, whether plants or animals, became organisms by the fusion of these primal animals. Those elements lose all individuality and create a higher unity. Lorenz Oken wrote many books on natural history for students and adults, founded a scholarly journal (contributing most of its articles), and organized scientific congresses. Pic.
