founded his famous " Mineralogisches-geologisclies Institiit". Here 

 during the foUowing twenty-eight years he attracted successive 

 generations of enthusiastic students from all countries, perfecting his 

 methods and applying them in a number of petrographical memoirs, 

 but doing still more important work by his example and influence on 

 the labours of liis devoted followers. 



In 1906, upon reaching the age of 70, Rosenbusch retired from his 

 professorship, the event being made the occasion of the publication of 

 a ' Festschrift ', in which his students from all pai ts of the world 

 published original memoirs devoted tq the science they had learned 

 from their gi'eat master. On January 20, 1914, Rosenhusch passed 

 away, after a short and severe illness, leaving a widow but no 

 children. 



No notice of Rosenhusch would be complete without a reference to 

 the amiability and charm of liis personality. He was a born teacher 

 and inspired tlie strongest feelings of affection in his pupils. They 

 loyed to dwell in after years on his conversations as he made the 

 round of his laboratory, his enthusiasm when, witli lighted cigar, he 

 demonstrated the existence of carbon dioxide in cavities of quiirtz, and 

 his constant insistence that no determination of a mineral should be 

 considered settled till every optical test had been applied. Ey his 

 scientific contemporaries in all countries he was e(]ually esteemed and 

 loved. Ever ready to exchange specimens, sections, and ideas, he 

 ■was modest and gentle in expressing dissentient views, and friendly 

 and generous in agreement and appreciation of the work of others. 

 Rosenhusch has left a great and enduring mark upon the geological 

 science of the nineteenth century.
