Researches on the Visual Organs of the Trilobites

"Researches on the Visual Organs of the Trilobites" by Gustaf Lindström is a scientific book from the late 1800s, which looks closely at the eyes and related body parts like the hypostoma of trilobites, an extinct group of sea creatures. The book tries to teach more about these old arthropods and how their vision developed, beginning by talking about the research collaboration between Lindström and G. Liljevall, along with the not-well-understood hypostoma, and previous publications, explaining how the current study wants to clear up how trilobites saw the world. To get there, the writer shares plans to carefully examine and then share information about the visual organs of lots of different trilobite types, and expresses a wish to correct past mistakes that scientists made when discussing their anatomy.
