[3] In 1621 Theophilus Müller and Giovanni Faber performed the first documented dissection of a rat.
Their pregnant specimen appeared to have a penis and testes as well as a uterus, so they described it as a hermaphrodite.
In fact the supposed penis was a clitoris, and the testes were vaginal glands.
[4] Federico Cesi had purchased the unpublished papers of the Fransicso Hernández expedition, part-edited by Nardo Antonio Recchi, containing a compendium of New World plants.
There was a Lincean project to send Müller to Mexico to complete the necessary research for the publication,[5] but nothing appears to have come of it.
