Leipzig, and Fehling at Stuttgart. At Munich he met 

 Pettenkofer and Buchner, but above all Liebig, the 

 latter, unless we except Wohler, the chief chemical 

 figure in Europe. At Berlin he met Eilhard Mitscher- 

 lich, known by his discoveries in isomorphism, and the 

 highly accomplished analytical chemist, Heinrich Rose, 

 both, like his great teacher, pupils of Berzeliiis, one of 

 the founders of modern chemistry. To this brilliant 

 group of scientists should be added Christian Friedrich 

 Schonbein, the chemical physicist and discoverer of 

 gun-cotton and ozone, Gustav Magnus, August Wil- 

 helm Hofmann, Rammelsberg, and the French chem- 

 ist, Henri Sainte-Claire Deville. These he met, and 

 many other scientific workers, and by all was cordially 

 received, his investigations and discoveries in organic 

 chemistry having already made his name familiar to 

 them.
