Twee infusoriën 1881

Jacob van Rees' "Twee infusoriën" (1881) is a detailed pen and ink drawing of two infusoria, single-celled organisms. The intricate details of the organisms, particularly the delicate hairs and internal structures, showcase van Rees' skillful hand and his meticulous observation of the microscopic world. Infusoria are common in freshwater environments, and this drawing provides a valuable glimpse into the beauty of microscopic life.
