Hermann Kopp (1817 1892) is best remembered today as a historian of chemistry, but during his lifetime he was one of the most eminent chemists of his day, and one of the earliest pioneers of physical chemistry. Late in his career he wrote an endearing fantasy about personified molecules. Published in 1882, Aus der Molecular-Welt (From the Molecular World) portrayed the intimate details of what might actually be happening in the sub-microscopic world; the atoms and molecules we meet there have agency, personalities, sometimes even dialog. Filled with appealing tropes, humor, and whimsical asides, Kopp s short book provided an examination of the chemistry and physics of his day that was always light-hearted on the surface, but often surprisingly profound. Properly interpreted, the book provides a revealing tour of nineteenth-century debates concerning chemical theory. It is here translated into English, richly annotated, and equipped with an illuminating preface by a leading historian of chemistry. It provides entertaining reading to practicing chemists, as well as new insights to historians of science."

Bei der Ausarbeitung der vorliegenden Schrift leiteten mich verschiedene Zwecke. Ich strebte, die Anfangsgrunde der Krystallographie leichtf&8slich darzulegen, zur practischen An- wendung der so erlangten theoretischen Kenntnisse oder zur Bestimmung wirklicher Krysta.lle anzuleiten und anzuregen, und ein Rulfsmittel zu geben, mitte1st dessen der Anfanger sich uber die Krysta.llform der wichtigsten Substanzen unter- richten koenne. Ausserdem wollte ich versuchen, fur die Er- werbung krystallographischer Kenntnisse ein Publikum etwas mehr zu gewinnen, welches sich im Ganzen bis jetzt nur wenig damit beschaftigt hat: das chemische. Dieselben Zwecke leiteten mich bei den Vortragen, welche ich seit sechs Jahren an der hiesigen Universitat vor Zuhoerern halte, deren Hauptstudium meistens die Chemie ist. Die Vor- kenntnisse, welche ich hier durchschnittlich vorgefunden habe, setzte ich auch bei der Ausarbeitung dieses Buches voraus; ich muss deutlicher sagen, dass ich sehr weIiig voraussetze. Die Art der Darstellung, nach welcher bei diesen Vortragen die krystallographischen Gesetze am klarsten wurden, ist die auch hier befolgte. Dass ich sehr wenig Vorkenntnisse voraussetze, mag ent- schuldigen und rechtfertigen, wenn die Darstellung durchgangig sehr elementar -und manchmal etwas weitlaufig erscheint. Auch VI Vorrede zur ersten Auflage. Wiederholungen waren mitunter nicht zu vermeiden, wollte ich duroh oefteres Erinnern an Einzelnes die Wichtigkeit des- selben dem Anfanger um so deutlicher hervortreten lassen.
