The images below (embryos of crustaceans) are intended as illustrations for articles on Embryons desséchés, a piano composition by Eric Satie - but they might as well be used in taxonomy or Darwinism related articles.
In early Darwinism these crustaceans (and notably also their embryos) were studied by Fritz Müller, in his book Facts and Arguments for Darwin, published in German in 1863, and available in English in 1869. The images below are taken from the Project Gutenberg publication of that book (E-text N° 6475).
