Moving from publication to another, the same text by Nerval sometimes shows unexpected variations that are not always easy to interpret. Is it a error that must be attributed to the distraction of the author or printer? Or is it a modification wanted by one of them? If it is deliberate, for what purpose? Among embarrassing cases, the article examines herboriseur / herborisateur, aigles éployé(e)s / déployés, and automne.
