The important studies on human embryos, originated by His, were carried on by his pupils, Keibel and Mall. This classic work written by American and German experts “has not yet been superseded” (D.S.B., late 20th century). The set was published "simultaneously" in German and English, though the German edition of the second volume was dated 1911. J. Playfair McMurrich translated the chapters written in German into English for the English language edition while Franz Keibel translated the chapters written in English into German for the German edition.
