Third Edition. The author, a Norwegian ophthalmologist, was an early campaigner for mandatory vision tests for ships' pilots and railway engineers. He published this pamphlet in the wake of Holmgren's De la cécité des couleurs dans ses rapports avec les chemins de fer et la marine (1877) on colour blindness, following a fatal train collision in Sweden that had prompted major concerns about vision and public safety. Ex-library with stamps and early ownership markings on front pastedown and title-page.
