Isis, oder encyclopädische Zeitung (verzüglich für Naturgeschichte, vergleichende Anatomie und Physiologie), VON OKEN. 41 vols.

Lorenz Oken, a leading light in the Nature-Philosophical School in Germany, produced important work in the field of biology. He founded the journal Isis, which published articles of great value; its incursion into the field of German politics led to a demand for the resignation of Oken from his professorship or the suppression of his journal. Oken resigned and continued to publish Isis.
