Poggendorff I, 992. Schelenz 564. Ferguson I, 358. NDB VII, 473. Hein-Schwarz I, 241. – First edition. "Already revered in his lifetime as a 'Patron of Protection of German Pharmacy' (Martius), Hagen has in fact decisively promoted the emancipation of the art of pharmacists into an independent, scientific discipline: once through his 53 years of teaching ... On the other hand, through his particularly methodological works, of which two have exerted the greatest influence for more than half a century: his 'Lehrbuch der Apothekerkunst', which is distributed in eight editions and translated into several languages... also his 'Grundrisse der Experimentalchemie', also published several times, which Kant - to whose round table H. belonged - as 'a logical masterpiece" (Hein-Schwarz I, 240). – A corner with a slight water edge, occasionally small patchy. All in all a nice specimen.
