Of the 98 pages of the monograph on icterus gravis neonatorum, 14 are devoted to a historical review. It is stated that since the discovery of the Rh factor, no attention has been given anywhere to the question of whether a pathogenetic relationship exists between Rh-conditioned and other forms of icterus neonatorum which clinically may be very similar or identical. The author utilizes 17 cases of familial icterus gravis neonatorum, of which he was able to observe 7 personally.
