This is a vintage scientific illustration from Ernst Haeckel's 'Anthropogenie' or 'The History of Development of Man'. It depicts four different primates in a comparative manner, labeled in German. **1. Chimpanse (Chimpanzee):** A young chimpanzee is shown seated, with its arms crossed and looking directly at the viewer. It has a dark coat and a relatively flat face. **2. Gorilla:** A gorilla is depicted in a seated position, with a more pronounced brow ridge and a slightly grim expression. It appears larger and more muscular than the chimpanzee. **3. Orang:** A young orangutan is shown seated with its arms raised and hands clasped. It has a reddish-brown coat and a more rounded face. **4. Neger (Negro/African Person):** A young African person is depicted seated with legs crossed and looking towards the left. The depiction is dated and carries problematic racial terminology. The illustration is done in a detailed, realistic style with fine lines and shading. The primates are positioned around a central point, suggesting a comparative study of their anatomy and features. The background is plain, emphasizing the subjects. The image is labeled with German text identifying each primate and the volume number (Vol. XI) in the upper right corner. The bottom of the image includes the publisher's information: 'Lith. Anst. v. C. Giltzsch, Jena'. **Important Note:** The term 'Neger' used in the illustration is an outdated and offensive racial slur. It's crucial to acknowledge this problematic terminology when discussing this historical image and understand its context within the history of scientific racism.
