In his studies of the origin, nature and destiny of the adenomyomata of the female sexual apparatus, Leopold Landau, Berlin, has developed some new knowledge of an old subject. The new matter has for the most part been accumulated within the last five years, and is so complete that the story of the origin, construction and treatment of these neoplasms may now be told in a purely pragmatic and sequential way.
