In the article “Politics by other means: Justus von Liebig and the German translation of John Stuart Mill's Logic” by Pat Munday, published in our December 1998 number, an unfortunate proof reading error occurred on p. 403. The third sentence should have read “Chemical methods, popular and professional publications about chemistry, technological applications, promoting the careers of former students and even politics – all were central concerns stemming from Liebig's notion of chemistry as the central science.” We apologize to Professor Munday for this error.
