First edition, illustrating Bouchut's ground-breaking technique of "cerebroscopy", now called ophthalmoscopy, used for examining the interior of the eye for diagnosis of brain disorders such as meningitis. He also invented a device, a set of tubes (Bouchut's tubes), for use in intubation of the trachea, as an alternative to tracheotomy in cases of diphtheria, preceding Macewen's first successful endotracheal intubation at the end of the 19th century.
