Lettres sur la certitude des signes de la mort où l'on rassure les citoyens de la crainte d'être enterrés vivans ; avec des observations et des expériences sur les noyés.

In this work in the pathophysiology of drowning, resuscitation and the legal diagnosis of death Louis sought to reassure the public that the risk of being buried alive was very low. He rejected a proposal for late burials (three days after the diagnosis of death) because of the risk of infection. He claimed that flaccid and soft character of the eyes is a characteristic, unmistakable sign of death, and that this occurred "in a few hours".  Louis also carried out many experiments to explain the mechanism of drowning. He demonstrated for the first time that water is introduced into the bronchi, and not into the stomach, during drownings. He also studied methods of resuscitation and warned of the dangers of pouring spirits into the mouth of an unconscious drowned person. At the end of his book Louis republished Winslow's thesis (No. 11407) on the uncertainty of the signs of death, with its French translation on the opposite pages.
